PROSPECTUS SUMMARY

About BIO-key International, Inc.

BIO-key International, Inc. (the "Company," "BIO-key," "we" or "us") is in the business of delivering advanced identification solutions and information services to law enforcement departments, public safety agencies and other government and private sector customers. Our mobile wireless technology provides first responders with critical, reliable, real-time data and images from local, state, and national databases. More than 2,500 police, fire and emergency services departments in North America currently utilize the our solutions, making us a leading supplier of mobile and wireless solutions for public safety.

Our scalable biometric finger identification technology identifies and authenticates users of wireless and enterprise data to improve security, convenience and privacy as well as reducing identity theft. Biometrics is the science of analyzing specific human characteristics which are unique to an individual in order to identify a specific individual from a broader population. Our technology scans a person's fingerprint and identifies that person within seconds without using a password, key card, personal identification number or any other identifying data. Fingerprint analysis is an accurate and reliable method to distinguish one individual from another and is generally viewed as less intrusive than many other biometric identification methods. We believe our technology and products will have a broad range of applications relating to protecting access to information and assets in both electronic and physical environments, including:

•: Delivering mission critical centralized enterprise information to field personnel graphically and wirelessly through standard off-the-shelf hardware devices;
•: Securing access to logical networks and applications;
•: Securing access to buildings and restricted areas; and
•: Prevention of identity and data theft.

Our technology provides a reliable and secure user identification/authentication system for public and private computer networks. WEB-key™ is designed to secure access to proprietary information residing on remote servers which is transmitted via the Internet. It is compatible with Oracle server software and new security features in Microsoft's Internet Explorer Versions 5.5 SP2 and 6.0. Network authentication is typically accomplished by using passwords. Since passwords can be lost, transferred, stolen or forgotten, we believe our WEB-key™ biometric solution is a more secure method for verifying the identity of remote users and eliminates the substantial administrative costs associated with tracking and reissuing new passwords.

On March 30, 2004, we acquired Public Safety Group, Inc. ("PSG"), a privately held leader in wireless solutions for law enforcement and public safety markets. PSG's primary technology is a software solution that provides police officers and other security personnel instantaneous access to criminal, civil and private database information in a wireless environment. PocketCop© is a handheld application that allows law enforcement officers to access state and federal databases over the wireless network for PalmOS, Windows CE and PocketPC. With the use of a portable wireless handheld device and PocketCop© application software, an authorized user can access suspect information such as wanted status, warrant status, vehicle registration and driver license status. With our acquisition of PSG, we believe there is a substantial market opportunity to integrate our VST™ and WEB-key™ biometric technologies with the PSG mobile solution.

On September 30, 2004, we acquired the Mobile Government Division ("Aether Mobil Government") of Aether Systems, Inc. ("Aether"). Pursuant to the Asset Purchase Agreement dated as of August 16, 2004 by and among the Company, Aether, Cerulean Technology, Inc. and SunPro, Inc., we paid Aether a purchase price of $10,000,000 in cash, subject to post-closing adjustments to reflect

changes in Aether Mobile Government's working capital and cash flows since June 30, 2004. In connection with this acquisition, we also issued a subordinated secured promissory note to Aether in the face amount of $6,884,588 (the "Aether Note"). The Aether Note evidences a contingent reimbursement obligation of the Company to Aether and a surety fee payable by the Company to Aether, in each case with respect to a letter of credit maintained by Aether for the Company's benefit in connection with the acquisition. Our obligations under the Aether Note are secured by a security interest granted to Aether in all or substantially all of our assets, subordinate to the security interests described in the "Convertible Debt Financing Transactions" section of this prospectus below.

Aether Mobile Government provides wireless data solutions for use by public safety organizations, primarily state and local police, fire and rescue and emergency medical services organizations, that enable such organizations to access law enforcement databases to validate identities and obtain suspect information. Its public safety solutions are integrated into fifty (50) different state databases, as well as local and federal databases, and its products deliver real-time information in seconds, without the need for human dispatchers or other resources.

Although biometric based solutions currently compete with more traditional security methods such as keys, cards, personal identification numbers and security personnel, biometric technology is becoming an acceptable approach to physical and logical security. Our current business plan is to:

•: License our core technology "VST" to original equipment manufacturers, systems integrators and application developers to develop and market products and applications which can then be sold to end users;
•: License WEB-key™, our web-based biometric authentication solution; and
•: Provide for "device independent" finger identification matching for virtually any application utilizing the latest advances in scanning technology.
•: License our wireless software solutions for law enforcement and public safety markets.

We have evolved from a development stage company to a revenue generating company, but we have sustained substantial losses to date. We completed a private placement equity offering in March 2004 that resulted in approximately $12,000,000 in gross proceeds to the Company and a private placement convertible debt offering in September 2004 that resulted in approximately $10,000,000 in gross proceeds to the Company (a portion of which was used to finance the acquisition of Aether Mobile Government), and management believes that we now have sufficient funds to meet our working capital requirements for at least the next twenty-four (24) months. To the extent that we will require additional capital to support our operations, expand our marketing and sales efforts and to execute our business plan, we may need to obtain additional financing.

Our principal executive offices are located at 1285 Corporate Center Drive, Suite 175, Eagan, Minnesota 55121 and our telephone number is (651) 687-0414.

RISK FACTORS

An investment in our common stock involves a high degree of risk. You should carefully consider the following information about certain of the risks of investing in our common stock, together with other information contained in this prospectus, before you decide to purchase our common stock.

Business and Financial Risks

Since our formation, we have historically generated minimal revenue and have sustained substantial operating losses.

From inception through December 31, 2003, we accumulated a deficit of approximately $27,676,000 and negative cash flow from operations of approximately $19,038,000. As of December 31, 2003, we had positive working capital of approximately $1,085,000, but a stockholders' deficit of approximately $9,136,000. Since our inception, we have focused almost exclusively on developing our core technology and have not generated any significant historical revenue. In order to generate revenue, we have developed a direct sales force and anticipate the need to retain additional sales, marketing and technical support personnel and incur substantial expenses. We cannot assure you that we will be able to secure these necessary resources, that a significant market for our technology will develop or that we will be able to achieve our targeted revenue.

Our technology has yet to gain widespread market acceptance and we do not know how large of a market will develop for our technology.

Biometric technology has received only limited market acceptance, particularly in the private sector. Our technology represents a novel security solution and we have not generated any significant sales. Although recent security concerns relating to identification of individuals has increased interest in biometrics generally, it remains an undeveloped, evolving market. Biometric based solutions compete with more traditional security methods including keys, cards, personal identification numbers and security personnel. Acceptance of biometrics as an alternative to such traditional methods depends upon a number of factors including:

•: the reliability of biometric solutions,
•: public perception regarding privacy concerns,
•: costs involved in adopting and integrating biometric solutions.

For these reasons, we are uncertain whether our technology will gain widespread acceptance in any commercial markets or that demand will be sufficient to create a market large enough to produce significant revenue or earnings. Our future success depends upon business customers adopting biometrics generally, and our solution specifically.

Biometric technology is a new approach to internet security which must be accepted in order for our WEB-key™ solution to generate significant revenue.

Our WEB-key™ authentication initiative represents a new approach to Internet security which has been adopted on a limited basis by companies which distribute goods, content or software applications over the Internet. The implementation of our WEB-key™ solution requires the distribution and use of a finger scanning device and integration of database and server side software. Although we believe our solution provides a higher level of security for information transmitted over the Internet than existing traditional methods, unless business and consumer markets embrace the use of a scanning device and believe the benefits of increased accuracy outweigh implementation costs, our solution will not gain market acceptance.

Our software may contain defects which will make it more difficult for us to establish and maintain customers.

Although we have completed the development of our core technology, it has only been used by a limited number of business customers. Despite extensive testing during development, our software may contain undetected design faults and software errors, or "bugs," that are discovered only after it has been installed and used by customers. Any such default or error in new or existing software or applications could cause delays in delivering our technology or require design modifications. These could adversely affect our competitive position and cause us to lose potential customers or opportunities. Since our technology is intended to be utilized to secure physical and electronic access, the effect of any such bugs or delays will likely have a detrimental impact on us. In addition, given that biometric technology generally, and our technology specifically, has yet to gain widespread acceptance in the market, any delays would likely have a more detrimental impact on our business than if we were a more established company.

While we have commenced a significant sales and marketing effort, we have only developed a limited distribution channel and may not have the resources or ability to sustain these efforts or generate any meaningful sales.

In order to generate revenue, we are dependent upon independent original equipment manufacturers, system integrators and application developers which we do not control. As a result, it may be more difficult to generate sales.

We market our technology through licensing arrangements with:

•: Original equipment manufacturers, system integrators and application developers which develop and market products and applications which can then be sold to end users; and
•: Companies which distribute goods, services or software applications over the Internet.

As a technology licensing company, our success will depend upon the ability of these manufacturers and developers to effectively integrate our technology into products and services which they market and sell. We have no control over these licensees and cannot assure you that they have the financial, marketing or technical resources to successfully develop and distribute products or applications acceptable to end users or generate any meaningful revenue for us. These third parties may also offer the products of our competitors to end users.

We face intense competition and may not have the financial and human resources necessary to keep up with rapid technological changes which may result in our technology becoming obsolete.

The Internet, facility access control and information security markets are subject to rapid technological change and intense competition. We compete with both established biometric companies and a significant number of startup enterprises as well as providers of more traditional methods of access control. Most of our competitors have substantially greater financial and marketing resources than we do and may independently develop superior technologies which may result in our technology becoming less competitive or obsolete. We may not be able to keep pace with this change. If we are unable to develop new applications or enhance our existing technology in a timely manner in response to technological changes, we will be unable to compete in our chosen markets. In addition, if one or more other biometric technologies such as voice, face, iris, hand geometry or blood vessel recognition is widely adopted, it would significantly reduce the potential market for our fingerprint identification technology.

We depend on our chairman of the board and chief executive officer and need additional marketing and technical personnel to successfully market our technology. We cannot assure you that we will be able to retain or attract such persons.

A loss of our current Chairman of the Board of Directors or Chief Executive Officer could severely and negatively impact our operations. We have an employment contract with Michael W. DePasquale, our Chief Executive Officer. Although the contract does not prevent him from resigning, it does contain confidentiality and non-compete clauses which are intended to prevent him from working for a competitor within one year after leaving our Company. We continue to retain additional employees with expertise in developing, marketing and selling software solutions. In order to successfully market our technology, we will need to retain additional engineering, technical support and marketing personnel. The market for such persons remains highly competitive and our limited financial resources will make it more difficult for us to recruit and retain qualified persons.

We cannot assure you that the limited intellectual property protection for our core technology provides a meaningful competitive advantage or barrier to entry against our competitors.

Our success and ability to compete is dependent in part upon proprietary rights to our technology. We rely primarily on a combination of patent, copyright and trademark laws, trade secrets and technical measures to protect our propriety rights. We have filed a patent application relating to both the optic technology and biometrics solution components of our technology wherein several claims have been allowed. More recently, we filed a patent application with respect to our VST™ (Vector Segment Technology), the core algorithm of our biometric identification solution. We cannot assure you that any patents will be issued, or that, if issued, that we will have the resources to protect any patent from infringement. Although we believe our technology does not currently infringe upon patents held by others, we cannot assure you that such infringements do not exist or will not exist in the future, particularly as the number of products and competitors in the biometric industry segment grows.

We may need to obtain additional financing to execute our business plan which may not be available. If we are unable to raise additional capital or generate significant revenue, we may not be able to continue operations.

Since our inception, we have not generated any significant revenue and have experienced substantial losses, including approximately $3,826,000 during 2003. We also have a stockholders' deficit as of December 31, 2003. In March 2004, we completed a private placement equity offering that resulted in approximately $12,000,000 in gross proceeds to the Company and a private placement convertible debt offering in September 2004 that resulted in approximately $10,000,000 in gross proceeds to the Company (a portion of which was used to finance the acquisition of Aether Mobile Government), and management now believes that we have sufficient funds to meet our working capital requirements for at least the next twenty-four (24) months. To the extent that we will require additional capital to support our operations, expand our marketing and sales efforts and to execute our business plan to substantially increase revenue, we may need to obtain additional financing through the issuance of debt or equity securities. We have not and cannot assure you that we will ever be able to secure any such financing on terms acceptable to us. If we cannot obtain such financing or generate such revenues, we may not be able to execute our business plan or continue operations.

We may not be able to successfully integrate recent acquisitions into our operations.

On September 30, 2004, we completed our transaction with Aether to purchase Aether Mobil Government based in Marlborough, Massachusetts, a provider of wireless data solutions for use by public safety organizations, as described further in the "Acquisition of Aether Mobile Government"

section of this prospectus. The integration of Aether Mobile Government into our operations involves a number of risks, including:

•: difficulty integrating operations and personnel;
•: diversion of management attention;
•: potential disruption of ongoing business;
•: inability to retain key personnel;
•: inability to successfully incorporate the acquired products and services into our product and service offerings and to develop new products and services; and
•: impairment of relationships with employees, customers or vendors.

Failure to overcome these risks or any other problems encountered in connection with the acquisition of Aether Mobile Government could slow our growth or lower the quality of our services, which could reduce customer demand. The result could be an adverse effect on our financial results.

We may not achieve profitability with respect to our law enforcement and public safety division if we are unable to maintain, improve and develop the wireless data services we offer.

We believe that our future business prospects depend in part on our ability to maintain and improve our current services and to develop new ones on a timely basis. Our services will have to achieve market acceptance, maintain technological competitiveness and meet an expanding range of customer requirements. As a result of the complexities inherent in our service offerings, major new wireless data services and service enhancements require long development and testing periods. We may experience difficulties that could delay or prevent the successful development, introduction or marketing of new services and service enhancements. Additionally, our new services and service enhancements may not achieve market acceptance. If we cannot effectively develop and improve services we may not be able to recover our fixed costs or otherwise become profitable.

Our law enforcement and public safety division depends upon wireless networks owned and controlled by others.

If we do not have continued access to sufficient capacity on reliable networks, we may be unable to deliver services and our sales could decrease. Our ability to grow and achieve profitability partly depends on our ability to buy sufficient capacity on the networks of wireless carriers such as Verizon Wireless, Bell South Corporation, Metrocall, Motient and AT&T Wireless and on the reliability and security of their systems. All of our services are delivered using airtime purchased from third parties. We depend on these companies to provide uninterrupted and bug free service and would not be able to satisfy our customers' needs if they failed to provide the required capacity or needed level of service. In addition, our expenses would increase and our profitability could be materially adversely affected if wireless carriers were to increase the prices of their services. Our existing agreements with the wireless carriers generally have one-year terms. Some of these wireless carriers are, or could become, our competitors and if they compete with us they may refuse to provide us with their services.

New laws and regulations that impact our law enforcement and public safety division could increase our costs or reduce our opportunities to earn revenue.

We are not currently subject to direct regulation by the Federal Communications Commission or any other governmental agency, other than regulations applicable to businesses in general. However, in the future, we may become subject to regulation by the FCC or another regulatory agency. In addition, the wireless carriers who supply us airtime and certain of our hardware suppliers are subject to

regulation by the FCC and regulations that affect them could increase our costs or reduce our ability to continue selling and supporting our services.

We granted a blanket security interest in all of our assets to the holders of our secured debt. If we are unable to make our required monthly payments on such debt, or any other event of default occurs, it could have a material adverse effect on our business and operations, and the debt holders may foreclose on our assets.

As part of our recent secured convertible debt financing transactions, we granted to Laurus Master Fund, Ltd. and another holder of such secured debt a blanket security interest in all of our assets, including assets of our subsidiary. See the "Convertible Debt Financing Transactions" section of this prospectus. In the event we default in payment on such debt, or any other event of default occurs under the relevant financing documents, 120% of the outstanding principal amount of the secured notes, plus accrued interest and fees will accelerate and be due and payable in full. See the "Convertible Debt Financing Transactions" section of this prospectus for a list of such potential events of default.

The cash required to pay such accelerated amounts on the secured notes following an event of default would most likely come out of our working capital. As we rely on our working capital for our day to day operations, such a default could have a material adverse effect on our business, operating results, or financial condition to such extent that we are forced to restructure, file for bankruptcy, sell assets or cease operations. In addition, upon an event of default, the holder of the secured debt could foreclose on our assets or exercise any other remedies available to them. If our assets were foreclosed upon, we were forced to file for bankruptcy or cease operations, stockholders may not receive any proceeds from disposition of our assets and may lose their entire investment in our stock.

Our obligations under our recently issued debt securities may adversely affect our ability to enter into potential significant transactions with other parties.

As a result of our recent debt financing transactions with Laurus Master Fund, Ltd., The Shaar Fund, Ltd. and other institutional and accredited investors, we incurred significant repayment obligations and we agreed to certain restrictive covenants. In particular, for so long as 25% of the aggregate principal amount of the convertible term notes remains outstanding, we will need the consent of the holders of such notes before we can take certain actions, including the following:

•: pay any dividends;
•: merge, effect a material reorganization, liquidate or dissolve;
•: materially change the scope of our business; or
•: create, incur or assume any debt (other than certain trade debt, equipment financings and debt for the purchase of assets in the ordinary course of business).

Accordingly, unless we obtain the noteholders' consent, we may not be able to enter into certain transactions. In addition, in connection with any potential significant transaction (such as a merger, sale of substantially all our assets, joint venture, or similar transaction), it is likely that we would have to pay off such debt obligations and have the applicable security interests released. Although we have the right at any time to prepay our debt obligations, we can only do so upon payment of 110% of the then principal balance, plus all other amounts owing under the notes. See the "Convertible Debt Financing Transactions" section of this prospectus. Based on an aggregate principal balance of $10 million, a complete prepayment would require a cash payment of $11 million. These provisions could have the practical effect of increasing the costs of any potential significant transaction, and restrict our ability to enter into any such transaction.

Our obligations to the holders of our outstanding preferred stock may further affect our ability to enter into potential significant transactions with other parties.

We will need to obtain the consent of the holders of a majority of the then outstanding shares of our Series C preferred stock before we can take certain actions, including the following:

•: a sale or other disposition of any material assets;
•: an acquisition of a material amount of assets;
•: engaging in a merger, reorganization or consolidation; or
•: incur or guaranty any indebtedness in excess of $50,000.

Accordingly, unless we obtain such consent, we may not be able to enter into certain transactions.

Risks Related To Our Common Stock

We have issued a substantial number of securities convertible into shares of our common stock which will result in substantial dilution to the ownership interests of our existing shareholders.

As of October 28, 2004, approximately 34,113,323 shares of our common stock were reserved for issuance upon exercise or conversion of the following securities:

•: 8,946,933 shares upon conversion of outstanding convertible term notes;
•: 14,737,915 shares upon exercise of outstanding stock options and warrants;
•: 804,208 shares upon exercise of options available for future grant under our existing option plans; and
•: 9,624,267 shares or more upon conversion of our outstanding shares of Series C convertible preferred stock.

The exercise or conversion of these securities will result in a significant increase in the number of outstanding shares and substantially dilute the ownership interests of our existing shareholders.

A substantial number of our convertible securities are convertible into shares of common stock at a conversion price of $.75 per share. Most of these shares are eligible for public resale. The trading price of our common stock and our ability to raise additional financing may be adversely effected by the influx into the market of such a substantial number of shares.

Our outstanding convertible preferred stock is convertible into 9,624,267 shares of common stock at a per share conversion price of $.75 which is substantially less than the current trading price of our shares. Although many of the shares issuable upon conversion of our convertible preferred stock are eligible for public resale under Securities and Exchange Commission Rule 144, we have agreed to file a registration statement to cover the public resale of all of these shares. This significant increase in the number of shares available for public sale may have a negative impact on the trading price of our shares and substantially dilute the ownership interests of our existing shareholders. In the event that our stock trades below $.75 per share, in order to raise additional financing we would likely be required to issue additional shares of common stock or securities convertible into common stock at a purchase or conversion price, as applicable, of less than $.75 per share. Any issuance of shares at a purchase price of less than $.75 per share would reduce the conversion price of our Series C preferred shares to such lower price. This would require us to issue additional shares upon conversion of our Series C preferred shares and further dilute the ownership interests of our existing shareholders. To the extent these factors are viewed negatively by the market, it may provide an incentive for persons to execute short sales of our common stock that could adversely affect the trading price of our common stock.

Applicable Securities and Exchange Commission rules governing the trading of "penny stocks" limits the trading and liquidity of our common stock which may affect the trading price of our common stock.

Our common stock currently trades on the OTC Bulletin Board. Because our common stock continues to trade below $5.00 per share, our common stock is considered a "penny stock" and is subject to Securities and Exchange Commission rules and regulations which impose limitations upon the manner in which our shares can be publicly traded. These regulations require the delivery, prior to any transaction involving a penny stock, of a disclosure schedule explaining the penny stock market and the associated risks. Under these regulations, certain brokers who recommend such securities to persons other than established customers or certain accredited investors must make a special written suitability determination regarding such a purchaser and receive such purchaser's written agreement to a transaction prior to sale. These regulations have the effect of limiting the trading activity of our common stock and reducing the liquidity of an investment in our common stock.

We do not intend to pay dividends in the foreseeable future.

We have never declared or paid a dividend on our common stock. In addition, the terms of our outstanding Series C preferred shares preclude us from declaring or paying a dividend on our common stock unless a dividend is also declared or paid, as applicable, on our Series C preferred shares. We intend to retain earnings, if any, for use in the operation and expansion of our business and, therefore, do not anticipate paying any dividends on our common stock in the foreseeable future.

The trading price of our common stock may be volatile.

The trading price of our shares has from time to time fluctuated widely and in the future may be subject to similar fluctuations. The trading price may be affected by a number of factors including the risk factors set forth in this prospectus as well as our operating results, financial condition, announcements of innovations or new products by us or our competitors, general conditions in the biometrics and access control industries, and other events or factors. Although we believe that approximately fifteen (15) registered broker dealers currently make a market in our common stock, we cannot assure you that any of these firms will continue to serve as market makers or have the financial capability to stabilize or support our common stock. A reduction in the number of market makers or the financial capability of any of these market makers could also result in a decrease in the trading volume of, and price of, our shares. In recent years, broad stock market indices, in general, and the securities of technology companies, in particular, have experienced substantial price fluctuations. Such broad market fluctuations may adversely affect the future trading price of our common stock.

Minnesota anti-takeover law and certain provisions of our articles of incorporation may discourage attempts to effect a change in control of our company, which may adversely affect the value of our common stock.

We are governed by the provisions of Section 302A.673 of the Minnesota Business Corporation Act ("MBCA"). In general, the law prohibits a public Minnesota corporation from engaging in a "business combination" (with an "interested shareholder") for a period of four years after the date of the transaction in which the person became an interested shareholder, unless the business combination is approved in a prescribed manner. A "business combination" includes mergers, share exchanges, asset sales, plan or proposal of liquidation or dissolution, recapitalization, issuance and transfers of shares in excess of five percent (5%) or more of the Company's shares. An "interested shareholder" means any person who owns directly or indirectly ten percent (10%) or more of a public corporation's outstanding voting stock or an affiliate or associate of a public corporation which owns, or within four years did own, ten percent (10%) or more of the public corporation's outstanding voting stock. These provisions regarding certain business combinations under the MBCA could have the effect of delaying, deferring,

or preventing a change in control of the company or the removal of existing management. We have no control over, and therefore cannot predict, what effect these impediments to the ability of third parties to acquire control of us might have on the market price of our common stock. In addition, we are authorized to issue 5,000,000 shares of preferred stock which may be issued by our Board of Directors on such terms and with such rights, preferences and designations as the Board may determine. Depending upon the rights, preferences and designations assigned to it, issuance of shares of preferred stock could delay, deter or prevent a change in control of our company to the detriment of our shareholders.

The selling security holders intend to sell their shares of common stock in the market, which sales may cause our stock price to decline.

The selling stockholders named in this prospectus intend to sell in the public market 10,996,925 shares of our common stock being registered in this offering. That means that up to 10,996,925 shares may be sold pursuant to this registration statement. Such sales may cause our stock price to decline. Our officers and directors and those shareholders who are significant shareholders as defined by the Securities and Exchange Commission will continue to be subject to the provisions of various insider trading and Rule 144 regulations.

The timing, amount and form of dividends, if any, will depend on, among other things, our results of operations, financial condition, cash requirements and other factors deemed relevant by our Board of Directors.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

This Management's Discussion and Analysis of Financial Condition and Results of Operations and other parts of this prospectus contain forward-looking statements that involve risks and uncertainties. All forward-looking statements included in this prospectus are based on information available to us on the date hereof, and we assume no obligation to update any such forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of a number of factors, including those set forth in the section captioned "RISK FACTORS" and elsewhere in this prospectus. The following should be read in conjunction with our audited financial statements included elsewhere herein.

Overview

The following should be read in conjunction with the consolidated financial statements of the Company included elsewhere herein.

We develop and market proprietary fingerprint identification biometric technology and software solutions. We pioneered the development of automated, finger identification technology that can be used without the aid of non-automated methods of identification such as a personal identification, password, token, smart card, ID card, credit card, passport, driver license or other form of possession or knowledge based identification. This advanced BIO-key™ identification technology improves both the accuracy and speed of finger-based biometrics and is the only finger identification algorithm that has been certified by the International Computer Security Association (ICSA).

Since our inception in 1993, we have spent substantial time and effort in completing the development of what we believe is the most discriminating and effective finger biometric technology available. During the past two years, our focus has shifted to marketing and licensing this technology. We have built a direct sales force of professionals with substantial experience in selling technology solutions to government and corporate customers. We expect to continue to add additional qualified personnel in 2004.

During 2003 and the first two quarters of 2004, we entered into a number of licensing and development agreements. Certain of these arrangements have resulted in our technology being used in commercial applications on a run time basis and we are beginning to generate recurring revenue. We will continue to focus a substantial amount of resources on our sales and marketing efforts and expect revenues to increase substantially during 2004. Our primary objective in 2004 is to generate revenue and increase the recognition, use and acceptance of our technology in the market. To accomplish this, all sales efforts are focused on moving evaluation and development relationships to run time license arrangements as quickly as possible. We continue to see increases in qualified leads resulting in evaluation licenses and run time licenses. Our biggest challenge is obtaining financial and human resources to pursue and follow up on all opportunities available to us.

Although recent security concerns relating to the identification of individuals has increased interest in biometrics generally, it has yet to gain widespread commercial acceptance. We continue to see increasing acceptance of biometric technology, however, and believe the market for our technology is large enough for us to become a successful revenue generating company. Continued concerns regarding security and increased corporate spending on technology are key external conditions which may affect our ability to execute our business plan.

On March 30, 2004, we acquired all of the outstanding capital stock of PSG, a privately-held provider of wireless solutions for law enforcement and public safety markets based in Winter Park, Florida, in exchange for an aggregate of 2,422,108 shares of our common stock, $500,000 in cash, and our assumption of $600,000 in aggregate net liabilities of PSG. The acquisition was completed pursuant

to the terms of an agreement and plan of merger by and among the Company, BIO-Key Acquisition Corp., a wholly-owned subsidiary of the Company, PSG and all of the shareholders of PSG. As a result of this transaction, PSG became a wholly-owned subsidiary of the Company and now constitutes a division of our business specializing in the law enforcement and public safety markets.

On March 31, 2004, we completed a private placement equity offering that resulted in approximately $12,000,000 in gross proceeds to the Company. Based on available cash resources, existing funding obligations and projected revenue, we believe our existing financial resources will now be sufficient to sustain operations for at least the next twenty-four (24) months. Our long-term viability and growth will depend upon the successful commercialization of our technologies and our ability to obtain adequate financing, among other matters, as to which there can be no assurances.

As more fully described in our Proxy Statement filed on July 21, 2004 with the Securities and Exchange Commission, we are actively pursuing strategic acquisitions that are expected to be accretive to operating results. To enable us to respond rapidly to acquisition opportunities, and to meet other future needs that could arise, we have obtained shareholder approval to raise the number of shares of common stock that we are authorized to issue from 60 million to 85 million. In that regard, on September 30, 2004, we completed our previously announced acquisition of Aether Mobile Government from Aether. Pursuant to the Asset Purchase Agreement dated as of August 16, 2004 by and among the Company, Aether, Cerulean Technology, Inc. and SunPro, Inc., the Company paid Aether a purchase price of $10,000,000 in cash, subject to post-closing adjustments to reflect changes in Aether Mobile Government's working capital and cash flows since June 30, 2004. In connection with this acquisition, the Company issued a subordinated secured promissory note to Aether in the face amount of $6,884,588 (the "Aether Note"). The Aether Note evidences a contingent reimbursement obligation of the Company to Aether and a surety fee payable by the Company to Aether, in each case with respect to a letter of credit maintained by Aether for the Company's benefit in connection with the acquisition. The Company's obligations under the Aether Note are secured by a security interest granted to Aether in all or substantially all of the Company's assets, subordinate to the security interest described in the "Convertible Debt Financing Transactions" section of this prospectus below.

On September 29, 2004, we entered into a securities purchase agreement with certain institutional and accredited investors. Under this agreement, the Company issued secured convertible term notes in the aggregate principal amount of $5,050,000, convertible into common stock of the Company in certain circumstances at $1.35 per share, and issued warrants to purchase an aggregate of 1,122,222 shares of our common stock at an exercise price of $1.55 per share. The Company's obligations under these financing documents are secured by a security interest in all or substantially all of the Company's assets. Also on September 29, 2004, we entered into a separate securities purchase agreement with existing shareholders of the Company and other accredited investors. Under this agreement, the Company issued unsecured convertible term notes in the aggregate principal amount of $4,768,000, convertible into common stock of the Company in certain circumstances at $1.35 per share, and issued warrants to purchase an aggregate of 1,059,553 shares of our common stock at an exercise price of $1.55 per share. The proceeds from each of these transactions were used in part to finance a portion of the Company's acquisition of Aether Mobile Government and will be used in part for working capital purposes.

Results of Operations

On March 30, 2004, we completed the acquisition of PSG, which now operates as our Law Enforcement and Public Safety division. The discussion below regarding our results of operations for the three and six months ended June 30, 2004 reflects the combined operations of our historic biometric technology licensing business and our new Law Enforcement and Public Safety division, whereas the corresponding periods in 2003 include only the operations of our historic biometric business. In order to present the following discussion in a manner to provide a more meaningful comparison between the two periods, where possible, we have quantified the material changes in our results of operations which are attributable to the operations of each of our businesses.

Three Months and Six Months Ended June 30, 2004 As Compared To Three Months and Six Months Ended June 30, 2003

Revenue:

We generated revenue of approximately $519,000 during the three month period ended June 30, 2004 as compared to approximately $13,000 during the corresponding period in 2003. Of this amount, approximately $128,000 was generated by our biometric technology business, representing an approximate $115,000 increase over the corresponding period in 2003. This increase was due to an increased number of licensing arrangements, some of which have moved from evaluation to recurring run time licenses. PSG, our law enforcement and public safety division which we acquired on March 30, 2004, accounted for approximately $391,000 of the remaining revenue during the three month period ended June 30, 2004.

We generated revenue of approximately $831,000 during the six month period ended June 30, 2004 as compared to approximately $41,000 during the corresponding period in 2003. Of this amount, approximately $253,000 was generated by our biometric technology business, representing an approximate $212,000 increase over the corresponding period in 2003. This increase was due to an increased number of licensing arrangements, some of which have moved from evaluation to recurring run time licenses. Our law enforcement and public safety division accounted for approximately $578,000 of the remaining revenue during the six month period ended June 30, 2004.

Consolidated revenue during the six month period ended June 30, 2004 consisted of approximately $580,000 from license fees, approximately $120,000 from product sales and approximately $131,000 from technical support services. We expect to continue to generate a majority of our revenue form license fees and the balance from technical support and product sales. As our evaluation customers move to run time licensing arrangements, we expect technical support fees to comprise a larger percentage of our consolidated revenue and provide increased recurring monthly revenue. We continue to expand our sales and marketing departments and expect to continue to add customers and increase revenue during 2004 in both our biometric and public safety divisions. We expect the majority of our consolidated revenue through the remainder of 2004 to continue to be generated by our public safety division.

Costs and Other Expenses

Cost of Products and Services Sold. Cost of products and services sold were approximately $95,000 during the three month period ended June 30, 2004 as compared to approximately $3,000 during the corresponding period in 2003. Of this amount, approximately $31,000 was attributed to sales by our biometric technology business, representing an approximate $28,000 increase from the corresponding period. Approximately $64,000 of the remaining cost of products sold, was attributed to our law enforcement and public safety division. As our revenue and customer base continues to grow, we expect these costs to continue to increase. Most initial sales by our law enforcement and public safety division involve the sale of a PDA, and most initial sales by our biometrics business involve the sale of a

scanner. We expect cost of products on a consolidated basis to continue to increase and be split approximately equally between our public safety and biometric technology businesses. Although we generate a margin on such sales, our future earnings, if any, will depend primarily upon licensing and technical support fees.

Cost of products and services sold were approximately $101,000 during the six month period ended June 30, 2004 as compared to approximately $6,000 during the corresponding period in 2003. Of this amount, approximately $37,000 was attributed to sales by our biometric technology business, representing an approximate $31,000 increase from the corresponding period. Approximately $64,000 of the remaining cost of products sold, was attributed to our law enforcement and public safety division.

Selling, general and administrative expenses. Selling, general and administrative expenses increased approximately $877,000 to approximately $1,346,000 during the three months ended June 30, 2004 as compared to approximately $469,000 during the corresponding period in 2003. Of this amount, approximately $878,000 was incurred by our biometric technology business, representing approximately a $409,000 increase over the corresponding period in 2003. Approximately $468,000 of the remaining selling, general and administrative expenses were incurred by our law enforcement and public safety division.

Of the approximately $877,000 increase in selling, general and administrative expenses during the three months ended June 30, 2004, approximately $312,000 was related to increased sales and marketing activity, approximately $169,000 was related to an increase in general administrative costs, approximately $106,000 was related to an increase in costs for administrative personnel, and approximately $290,000 was related to an increase in professional services incurred in connection with additional SEC filings and the audit of PSG. Although we continue to closely monitor expenses, we retained 5 additional employees in connection with our recent acquisition of PSG, and have expanded both our direct sales force, marketing and technology support departments. We expect continued increases in these functions during 2004 as we continue to focus on generating additional revenue and supporting our growing customer base. Accordingly, we expect selling, general and administrative expenses to continue to increase during 2004.

Selling, general and administrative expenses increased approximately $1,130,000 to approximately $2,167,000 during the six months ended June 30, 2004 as compared to approximately $1,037,000 for the corresponding period in 2003. Of this amount, approximately $1,699,000 was incurred by our biometric technology business, representing an approximate $662,000 increase over the corresponding period in 2003. The remaining increase approximately $468,000 was incurred by our law enforcement and public safety division.

Of the approximate $1,130,000 increase in selling, general and administrative expenses during the six months period ended June 30, 2004, approximately $257,000 was due to an increase in sales and marketing costs as we continue to focus substantial resources to generating revenue, approximately $141,000 was due to an increase in executive personnel costs, approximately $356,000 was due to an increase in general administrative costs and approximately $376,000 was related to an increase in professional services incurred in connection with additional SEC filings and the audit of PSG.

Research and Development. Research, development and engineering expenses increased approximately $98,000 to approximately $352,000 during the three months ended June 30, 2004 as compared to approximately $254,000 during the corresponding period in 2003. Of this amount, approximately $276,000 was incurred by our biometric technology business, representing an approximate $22,000 increase over the corresponding period in 2003. The remaining increase of approximately $76,000 was incurred by our law enforcement and public safety division. Of the approximate $98,000 increase in research, development and engineering expenses approximately $60,000 was related to an increase in general development expense, and approximately $38,000 related to an increase in personnel costs. Having completed the development of our core technology, research and

development expenses in 2004 will consist of enhancing existing software and reacting to customer feedback. We expect research and development costs to stabilize during 2004 and be incurred primarily by our biometrics business.

Research, development and engineering expenses increased approximately $140,000 to approximately $615,000 during the six months ended June 30, 2004 as compared to approximately $475,000 during the corresponding period in 2003. Of this amount, approximately $539,000 was incurred by our biometric technology business, representing an approximate $64,000 increase over the corresponding period in 2003. Approximately $76,000 of the remaining increase was incurred by our law enforcement and public safety division. Of the approximate $140,000 increase in research, development and engineering expenses approximately $35,000 was related to an increase in general development expense, and approximately $105,000 related to an increase in personnel costs.

Interest Expense. Interest expense was approximately $1,000 and $137,000 during the three and six month periods ended June 30, 2004, respectively, as compared to approximately $303,000 and $594,000 during the corresponding periods in 2003, respectively. Substantially all of the interest expense was incurred by our biometric technology business. The decrease in interest expense during the three and six months ended June 30, 2004 was due to the decrease in long-term obligations. As of the date of this prospectus, all term indebtedness has been converted into equity.

Year Ended December 31, 2003 As Compared To Year Ended December 31, 2002:

Revenues

We generated revenues of approximately $524,000 during 2003 as compared to approximately $155,000 during 2002. Our 2003 revenues consisted of approximately $411,000 from license fees and approximately $113,000 from products and services as compared to approximately $131,000 from license fees and approximately $24,000 from sales of products and services during 2002. We expect ninety percent (90%) of our future revenues to be generated from license fees and the balance from product sales. We expect revenues to continue to increase during 2004, as we enter into new licensing arrangements and our existing arrangements lead to recurring run time licenses.

Costs and Other Expenses

Selling, general and administrative expenses. Selling, general and administrative expenses increased approximately $192,000 to approximately $2,118,000 during 2003 as compared to approximately $1,926,000 in 2002. Of the increase, approximately $182,000 was related to increased sales and marketing activity, approximately $137,000 was related to an increase in general administrative costs, approximately $266,000 was related to an increase in costs for administrative personnel, and approximately $76,000 was related to an increase in professional services. These amounts were offset by a decrease in marketing consulting costs of approximately $469,000 in 2003. Although we continue to closely monitor expenses, we expect marketing, sales and technical support expenses to increase in 2004 as we continue to focus on generating revenue and supporting our growing customer base. Accordingly, we expect selling, general and administrative expenses to increase during 2004.

Research and Development. Research, development and engineering expenses decreased approximately $47,000 to approximately $1,037,000 in 2003 as compared to approximately $1,084,000 in 2002. Of the decrease, approximately $58,000 was related to a decrease in general development expense, and approximately $44,000 was related to a decrease for services of outside programming sub-contractors. This was offset by an approximate $55,000 increase in personnel costs. Having completed the development of our core technology, research and development expenses in 2004 will consist of enhancing existing software and reacting to customer feedback. We expect research and development costs to stabilize during 2004.

Interest Expense. Interest expense decreased approximately $53,000 to approximately $1,110,000 in 2003 as compared to approximately $1,163,000 in 2002. The decrease was due to a net decrease during 2003 of the amortization of discounts applicable to convertible debt issued during 2001 arising from the warrants issued with such convertible debt and the beneficial conversion features of such debt. We recently converted $6.5 million of long term debt and accrued interest into convertible preferred stock. Unless we are required to raise any necessary financing through issuance of debt securities, we expect interest expenses to decrease substantially in 2004.

Net Operating Loss Carryforwards

As of December 31, 2003, we had federal and Minnesota net operating loss carryforwards of approximately $24,504,000 and $12,406,000, respectively. Such carryforwards expire between 2011 and 2023 and will be limited in the future due to a change in ownership of the Company as defined in the Internal Revenue Code.

Liquidity and Capital Resources

Net cash used in operating activities during the six months ended June 30, 2004 was approximately $2,307,000 compared to approximately $1,307,000 during the six months ended June 30, 2003. The primary use of cash for both years was to fund the net losses. Net cash used in investing activities for the six months ended June 30, 2004 was approximately $6,541,000 compared to net cash used in investing activities of approximately $8,000 for the corresponding period in 2003 and consisted primarily of $5,887,500 invested in government bonds, $498,937 invested in the acquisition of PSG, $50,000 invested in Classifeye, and $79,089 invested in capital equipment additions. Net cash provided by financing activities during the six months ended June 30, 2004 was approximately $11,673,000 compared to approximately $1,553,000 in the corresponding period in 2003 and consisted primarily of $11,249,000 from sales of our common stock and approximately $1,000,000 from long term borrowings. These amounts were offset approximately $400,000 for a note repayment, approximately $100,000 for repurchasing warrants, approximately 44,000 in repayment of advances from a shareholder, and approximately $32,000 for other items.

Working capital increased approximately $3,161,000 during the six months ended June 30, 2004 to approximately $4,246,000 compared to approximately $1,085,000 as of December 31, 2003. This increase was due to an approximate $11,249,000 increase in cash as a result of the completion of our recent private placements of our equity securities. This amount was offset by the purchase of approximately $5,888,000 of marketable debt securities classified as held-to-maturity securities. Pursuant to an available credit facility, we can access an amount equal to up to 90% of the current market value of such marketable debt securities at a cost of funds equal to or less then the effective interest earned on such securities.

Since January 7, 1993 (date of inception), our capital needs have been principally met through proceeds from the sale of equity and debt securities. We do not currently maintain a line of credit or term loan with any commercial bank or other financial institution except as described in the immediate preceding paragraph.

On October 31, 2003, we entered into an amendment to the January 27, 2003 note purchase agreement with The Shaar Fund Ltd. ("Investor") to provide up to $2,500,000 of additional financing pursuant to the terms of a secured promissory note (the "Secured Note"). Of this amount, $600,000 was advanced at closing and $1,900,000 was funded between December 3, 2003 and March 29, 2004. The Secured Note was due October 1, 2005, secured by substantially all of our assets including our intellectual property, accrued interest at the rate of 7% per annum payable on maturity, and may be prepaid without penalty. The principal amount and accrued interest was convertible at the option of the Investor into either shares of our common stock at a conversion price of $.75 per share or shares of

our Series C preferred stock (the "Series C Shares") at a conversion price of $100 per share. The Secured Note also provided that in the event we completed a private placement of our equity securities resulting in gross proceeds in excess of $5,000,000 on or before June 30, 2004, some or all of the principal and accrued interest shall, at the option of the Investor, be either converted into such equity securities at a conversion price equal to the sale price of such securities or repaid in cash. Upon the closing of our recent private placement equity offering, the Investor elected to convert $347,500 of the principal amount of the Secured Note into shares of our common stock and warrants to purchase shares of our common stock, each issued to the Investor in connection with such private placement.

Pursuant to a recapitalization transaction completed on March 3, 2004, all existing promissory notes payable to the Investor, other than the Secured Note, together with all accrued and unpaid interest due thereon (approximately $6,500,000) were cancelled and converted into 65,000 Series C Shares. Series C Shares are convertible into common stock at a conversion price of $.75 per share. In the event that the average closing bid price of our common stock is less than $1.00 per share for thirty (30) consecutive days at any time after March 3, 2007, we will be required to redeem the Series C Shares at a redemption price of $100 per share plus all accrued and unpaid dividends due thereon. In connection with the recapitalization transaction, the Investor sold $375,000 of the principal amount of the Secured Note to Thomas J. Colatosti, our Chairman of the Board of Directors.

On March 30, 2004, the Investor elected to convert $1,827,463 of principal and accrued interest due under the Secured Note into 18,275 Series C Shares. Also on March 30, 2004, the Investor elected to exchange all of the issued and outstanding shares of our series B preferred stock and accrued and unpaid dividends thereon and all accrued and unpaid interest on such dividends into 5,257 additional Series C Shares. On April 29, 2004, Mr. Colatosti elected to convert $375,000 of the principal amount of the Secured Note into 3,750 Series C Shares. As a result of these conversions, as of the date of this report, we have no outstanding indebtedness other than as described in the "Convertible Debt Financing Transactions" section of this prospectus and current liabilities.

Between April 7, 2004 and June 21, 2004, we issued an aggregate of 2,237,198 shares of common stock upon conversion of 16,600 shares of the Company's Series C 7% Convertible Preferred Stock and $17,898 of dividends due theron to the Shaar Fund.

On March 31, 2004, we entered into a securities purchase agreement with certain institutional and accredited investors pursuant to which we issued and sold an aggregate of 8,888,928 shares of our common stock and warrants (the "Warrants") to purchase an aggregate of 4,444,464 shares of our common stock. The investors paid an aggregate purchase price of $1.35 for each share of common stock and Warrant to purchase 0.5 of a share of common stock, resulting in gross proceeds to of approximately $12,000,000.

On March 30, 2004, we completed the acquisition of PSG in exchange for an aggregate of 2,416,108 shares of our common stock, $500,000 in cash, and our assumption of $600,000 in net liabilities of PSG. Any liability or obligation of PSG in excess of such $600,000 limitation will be solely the responsibility of the former shareholders of PSG. In connection with this acquisition, we also issued 6,000 shares of our common stock to Harward Investments, Inc. ("Harward") pursuant to an arrangement involving the discharge of certain outstanding debt obligations of PSG to Harward as of March 30, 2004.

Additional earnout consideration, determined as a proportion of qualified revenues, as defined, attained by the acquired business during fiscal years 2004 and 2005, may be paid to the former shareholders of PSG. During 2004, earnout consideration, if any, will be paid at the following rates: Five percent (5%) of all 2004 Qualifying Revenue less than $2 million, less the Accounts Receivable Holdback; as defined; Ten percent (10%) of all 2004 Qualifying Revenue equal to or greater than $2 million but less than $4 million; Twenty percent (20%) of all 2004 Qualifying Revenue equal to or greater than $4 million but less than $7 million; and Thirty percent (30%) of all 2004 Qualifying

Revenue equal to or greater than $7 million. During 2005, earnout consideration, if any, will be paid at the following rates: Ten percent (10%) of all 2005 Qualifying Revenue equal to or greater than $7 million but less than $10 million; and Twenty percent (20%) of all 2005 Qualifying Revenue equal to or greater than $10 million. We will make payments of such additional consideration on the last day of the month following each month in which the acquired business achieves specified revenue milestones during fiscal years 2004 and 2005. Such payments will be made in cash, unless the aggregate amount of earnout consideration exceeds sixty percent (60%) of the aggregate consideration we paid in the merger transaction. Any such excess amounts will be paid in shares of our common stock priced as of two (2) days prior to the date on which any earnout payment becomes due.

We have announced our intention to actively pursue strategic acquisitions that are expected to be accretive to operating results. We believe that an active acquisition strategy is timely because (i) companies with synergistic technology and/or market channels can combine to respond to the need in the homeland security market for complete technology solutions and to create operating efficiencies and (ii) there are many companies in the technology sector that have over-invested in the development stage and now lack sufficient financial resources to invest in the sales and marketing capabilities necessary for growth. To enable us to respond rapidly to acquisition opportunities, and to meet other future needs that could arise, we obtained shareholder approval to increase the number of shares we are authorized to issue from 60 million to 85 million. While some of these newly authorized shares could be used as currency for acquisitions, we may raise the additional capital required for acquisitions through the issuance of convertible instruments that would not be immediately convertible into common stock.

On September 30, 2004, we completed our acquisition of Aether Mobil Government. Pursuant to the Asset Purchase Agreement dated as of August 16, 2004 by and among the Company, Aether, Cerulean Technology, Inc. and SunPro, Inc., the Company paid Aether a purchase price of $10,000,000 in cash, subject to post-closing adjustments to reflect changes in Aether Mobile Government's working capital since June 30, 2004. In connection with this acquisition, the Company issued a Subordinated Secured Promissory Note to Aether in the face amount of $6,884,588 (the "Aether Note"). The Aether Note evidences a contingent reimbursement obligation of the Company to Aether and a surety fee payable by the Company to Aether, in each case with respect to a letter of credit maintained by Aether for the Company's benefit in connection with the acquisition. The Company's obligations under the Aether Note are secured by a security interest granted to Aether in all or substantially all of the Company's assets, subordinate to the security interest described in the "Convertible Debt Financing Transactions" section of this prospectus below.

On September 29, 2004, we entered into a Securities Purchase Agreement (the "Senior Purchase Agreement") with Laurus Master Fund, Ltd. ("Laurus") and certain other institutional and accredited investors (together with Laurus, the "Senior Investors"). Under the Senior Purchase Agreement, the Company issued secured convertible term notes (the "Senior Convertible Notes") in the aggregate principal amount of $5,050,000, convertible into common stock of the Company in certain circumstances at $1.35 per share, and issued warrants (the "Senior Warrants") to purchase an aggregate of 1,122,222 shares of our common stock at an exercise price of $1.55 per share. The proceeds from this transaction were used to finance in part the Company's acquisition of Aether Mobile Government. The Company's obligations under the Senior Purchase Agreement, the Senior Convertible Notes and the Senior Warrants are secured by a security interest in all or substantially all of the Company's assets.

Also on September 29, 2004, we entered into a Securities Purchase Agreement (the "Subordinated Purchase Agreement") with the Investor and other existing shareholders of the Company and accredited investors (collectively, the "Subordinated Investors"). Under the Subordinated Purchase Agreement, the Company issued unsecured convertible term notes (the "Subordinated Convertible Notes") in the aggregate principal amount of $4,768,000, convertible into common stock of the Company in certain circumstances at $1.35 per share, and issued warrants (the "Subordinated

Warrants") to purchase an aggregate of 1,059,553 shares of our common stock at an exercise price of $1.55 per share. The proceeds from this transaction were used in part to finance a portion of the Company's acquisition of Aether Mobile Government and will be used in part for working capital purposes. Please see the "Convertible Debt Financing Transactions" section of this prospectus for a more complete description of the transactions consummated in connection with the Senior Purchase Agreement and the Subordinated Purchase Agreement.

Our future liquidity and capital requirements will depend upon numerous factors, including:

•: our ability to license our technology to original equipment manufacturers, systems integrators and application developers;
•: our ability to successfully integrate PSG's and Aether Mobile Government's technology and customer relationships into our current business plan;
•: the costs and timing of product development efforts and the success of these efforts;
•: our ability to maintain and grow quality customer base; and
•: biometric technology market developments.

As of the date of this prospectus, we had cash resources of approximately $3,200,000 and no debt other than as described in the "Convertible Debt Financing Transactions" section of this prospectus and current liabilities. We currently require approximately $400,000 per month to conduct our operations. During the first two quarters of 2004, we generated approximately $831,000 of revenue and expect to continue to generate increasing revenue from existing and new relationships during 2004.

We now believe our current cash resources and anticipated cash flow from current operations will enable us to maintain operations at current levels for at least the next twenty-four (24) months. We may need to obtain additional funding to (i) conduct the sales, marketing and technical support necessary to execute our plan to substantially grow operations, increase revenue and serve a significant customer base; and (ii) pursue our acquisition strategy. While anticipated revenues are expected to defray operating expenses and reduce the need for additional financing, they are not expected to be sufficient for us to significantly expand operations. To the extent that we would require such additional funding, no assurance can be given that any form of additional financing will be available on terms acceptable to us, that adequate financing will be obtained to meet our needs, or that such financing would not be dilutive to existing stockholders. If available financing is insufficient or unavailable or we fail to continue to generate meaningful revenue, we may be required to further reduce operating expenses, delay the expansion of operations, or be unable to pursue merger or acquisition candidates.

DESCRIPTION OF THE BUSINESS

Overview

The Company was formed in 1993 and is in the business of delivering advanced identification solutions and information services to law enforcement departments, public safety agencies and other government and private sector customers. Our mobile wireless technology provides first responders with critical, reliable, real-time data and images from local, state, and national databases. More than 2,500 police, fire and emergency services departments in North America currently utilize the our solutions, making us a leading supplier of mobile and wireless solutions for public safety. Our scalable biometric finger identification technology identifies and authenticates users of wireless and enterprise data to improve security, convenience and privacy as well as reducing identity theft. Biometric technology, the science of analyzing specific human characteristics which are unique to each individual in order to identify a specific person from a broader population, is an emerging technology. Fingerprint analysis is an accurate and reliable method to distinguish one individual from another and is viewed as less intrusive than many other biometric identification methods. As a result, fingerprint analysis has gained the most widespread use for biometric identification. Biometric technology represents a novel and accurate approach to identity verification and authentication which is now being used in limited applications and is gaining acceptance in the government, commercial and consumer markets.

We have pioneered the development of high performance automated finger identification technology that can be used without the aid of non-automated methods of identification such as a personal identification number (PIN), password, token, smart card, ID card, credit card, passport, driver license or other form of possession based or knowledge based identification.

Our advanced BIO-key™ identification technology improves both the accuracy and speed of finger-based biometrics and is the only finger identification algorithm that has been certified by the International Computer Security Association. Our proprietary biometric technology scans a person's fingerprint and identifies a person, typically within a few seconds, without the use of any other identifying data. We believe our fingerprint identification technology will have a broad range of possible applications relating to information security and access control, including:

•: Securing Internet sites and electronic transactions
•: Securing access to logical networks and applications
•: Securing access to buildings and restricted areas
•: Securing mobile devices such as cell phones and PDA's

In addition to these technologies, on March 30, 2004, we acquired Public Safety Group, Inc. ("PSG"), a privately held leader in wireless solutions for law enforcement and public safety markets. PSG's primary technology, PocketCop©, is a software solution that provides police officers and other security personnel instantaneous access to important criminal, civil and private database information in a wireless environment. PocketCop© is the first and only copyrighted handheld application that allows law enforcement officers to access state and federal databases over the wireless network for PalmOS, Windows CE and PocketPC. With the use of a portable wireless handheld device and PocketCop© application software, an authorized user can access suspect information such as wanted status, warrant status, vehicle registration and driver license status. PSG has deployed its technology in numerous police departments in the United States, including the statewide deployment for the Massachusetts State Police and has developed a number of important strategic marketing partnerships including Hewlett Packard.

On September 30, 2004, we completed a transaction with Aether Systems, Inc. to purchase its Mobil Government division ("Aether Mobil Government"). Aether Mobile Government provides wireless data solutions for use by public safety organizations, primarily state and local police, fire and

rescue and emergency medical services organizations. Its public safety solutions are integrated into fifty (50) different state databases, as well as local and federal databases, and its products deliver real-time information in seconds, without the need for human dispatchers or other resources. Together with PSG, Aether Mobile Government now comprises the Law Enforcement and Public Safety Division of our business.

Our current business plan is to:

•: License our core technology "VST" to original equipment manufacturers, systems integrators and application developers to develop products and applications which utilize our core technology.
•: License WEB-key™, our web-based biometric authentication solution.
•: Provide for "device independent" finger identification matching for virtually any application utilizing the latest advances in scanning technology.
•: License our wireless software solutions for law enforcement and public safety markets.

We actively market and sell our technology principally to biometric system integrators and value added resellers focused on the security and logical access markets. A number of our customers have begun to deploy our technology on a run-time basis which is generating recurring quarterly revenues. After years of technology and product development, we have evolved from a development stage company to a revenue generating company.

Market Overview

Recent concerns relating to Homeland Security and the need for identification of individuals has resulted in an increased interest in biometrics. Biometric based solutions currently compete with more traditional security methods such as keys, cards, personal identification numbers and security personnel, as well as competing biometric technologies including voice, face, iris and hand geometry. The market for business-to-business and business-to-consumer transactions is substantial and continues to grow. Such transactions are subject to fraud resulting in unauthorized individuals gaining access to confidential information. Identity theft is one of the most pressing issues facing corporations today. We believe our biometric technology provides a more reliable method for confirming the identity of persons in local or remote locations than existing traditional methods.

Additionally, law enforcement and public safety are large and growing markets. The ability to quickly and accurately collect data from a variety of database sources and formats and deliver it to first responders opens a new framework to bring real time intelligence to security officers deployed in the field. With our acquisition of PSG, we believe there is a substantial market opportunity to integrate our VST™ and WEB-key™ biometric technologies with the PSG mobile solution.

Biometric technology is becoming an acceptable approach to physical and logical security. Acceptance of biometrics as an alternative to traditional security methods depends upon a number of factors including:

•: The reliability of biometric solutions
•: Public perception regarding privacy concerns
•: Costs involved in adopting and integrating biometric solutions

Commercial markets have been slow to accept biometrics as a viable alternative to current security methods. As a result, the primary competition for biometric technology has been the traditional security methods described above. With respect to competing biometrics, each has its strength and weaknesses and none has emerged as a market leader. Fingerprint identification is generally viewed as inexpensive

and non-intrusive. Iris scanning is viewed as accurate, but also as inconvenient to use and expensive. Facial recognition has recently received substantial attention, however, it suffers from accuracy limitations. In summary, the market for biometric technology is evolving.

We market and sell our wireless data solutions primarily to state and local law enforcement agencies throughout the United Sates. We are establishing a strong customer base and expect continued growth in this division particularly in the current environment of heightened security concerns. We believe there is a substantial market opportunity to integrate our VST™ and WEB-key™ biometric technologies with the PSG mobile solution and the Aether Mobile Government solution. The integration will provide us with the ability to offer a unique wireless solution and the opportunity to provide a meaningful upgrade to all existing customers of PSG and Aether Mobile Government. We expect to complete the integration of the PSG-related technologies during the third quarter of 2004, and will continue to integrate the Aether Mobile Government-related technologies over the course of the next several quarters.

Technology

We have developed proprietary fingerprint identification technology consisting of:

•: VST™ (Vector Segment Technology), our patent pending core algorithm which creates a mathematical representation of a fingerprint based on its particular characteristics.
•: Software which translates and standardizes the image of the fingerprint for computer analysis ("Biometric Solution").
•: SDK (Developers Tool Kit), a biometric application development tool which facilitates integration of our technology for vertical market applications.

Utilizing these technologies, we continue to develop identification products and software solutions which are designed to assure that only individuals comprising an approved fingerprint in an online or embedded database are allowed access to an application through real time authentication.

Vector Segment Technology. Our information technology security solutions are built around our patent pending VST™ (Vector Segment Technology) which processes features of a live fingerprint. These features are reduced to a mathematical representation unique to the individual. When a person seeking access to a computer network or restricted area places his or her finger on a reader, a new mathematical representation is generated which is compared to an on-line database to determine whether it matches any mathematical representation on file. If there is a match, the person is identified and given access to the application, computer network, Web Site or restricted area. This can be accomplished without the use of a key, password, user-Id, card, PIN or token. The actual fingerprint is not typically stored in the database for commercial applications. For a more complete description of VST, see "Current Offerings" below.

De-coupling of Technologies. Over the years we have modified our core Vector Segment Technology by de-coupling the core identification algorithm from the reader technology. Our finger identification technology is hardware independent and can be integrated with virtually any finger reading devise. Enrollments or capture of an individual's biometric identification can be done on one type of scanner and looked-up or identified for a match on another type of scanner. This capability is unique in the biometric market and allows our software to be used and integrated with almost any finger scanning hardware.

Identification Verses Verification Technology. We believe our Vector Segment Technology is superior to similar technologies utilized by our competitors. Unlike many of the biometric technologies currently available, our technology identifies the fingerprint of an unknown person by searching a database to determine whether the current scanned mathematical representation matches any

previously stored mathematical representation. Most of our fingerprint competitors simply verify that the fingerprint image of a known person matches a previously stored copy or model of that individual's fingerprint. By their very nature, such verification systems require an additional item of data such as a PIN or access card to initially identify the user. Verification systems do not eliminate the need for cumbersome access cards, keys or PIN numbers and the administrative costs associated with the distribution and replacement of such data. By contrast, our identification technology typically does not require any identifying data other than a person's fingerprint. We believe this provides us with a meaningful competitive advantage in the marketplace.

Current Offerings

The following is a description of the status of each of our current offerings.

VST (Vector Segment Technology) SDK (Systems Developer Kit). Our SDK is a means of delivering our patent-pending finger identification algorithm, called Vector Segment Technology (VST), as an integrated software into existing and new applications. The VST SDK is a software kit licensed to original equipment manufacturers, systems integrators and application developers for the purpose of permitting them to develop biometric applications for distribution to their respective customers.

The VST SDK improves both the accuracy and speed of fingerprint-based security systems. Traditional fingerprint analysis classifies fingerprints by mapping their Minutiae Reference Points—distinct features in specific locations. Most automated fingerprint identification systems create a template of these minutiae reference points and uses it as the basis for comparison and verification. However, strictly minutiae-based templates cannot achieve a high level of differentiation, making them unsuitable for real-time identification applications. To achieve rapid verification, they often compromise on detail, supplementing the fingerprint template with a user ID or password. This enables quick one-to-one matching, but not true identification. VST transcends the conflict between differentiation and speed by mapping the fingerprint in an entirely new way. Instead of focusing on minutiae point coordinates, VST also analyzes the vector segment relationships in the entire fingerprint pattern. The result is a highly informative representation of the finger packaged as a mathematical model.

Unlike other algorithms, VST processes hundreds of data relationships for each element in the finger model. Because this data is concisely expressed, VST makes it possible to rapidly identify people based on their finger alone, without a user ID, password or smart card. This allows for the true identification of users, not just verifying the identity of a known user. No security system can achieve total security as long as a user's identifying data can be stolen or duplicated. Whereas a user ID, a password or even a scanned fingerprint image can be stolen, the mathematical model produced by VST cannot. Once a finger is scanned and converted to a VST mathematical model, the scanned image is destroyed. All that remains is a mathematical model that cannot be decoded to obtain the original fingerprint image.

WEB-key™. WEB-key™ is a biometric identification/authentication software solution designed to secure Web based applications through the use of a Web based browser plug-in and a server side plug-in. WEB-key™ is designed to provide security and identification assuring that a remote user is in fact who they say they are without the need of other identifying data. WEB-key™ protects personal information such as credit card information, addresses, account numbers and other private data by only disseminating such information upon the authorization of the owner of such information as determined by such person's fingerprint.

WEB-key™ is an Internet ready three-tiered Internet application architecture software security solution. We license WEB-key™ as an integrated solution of our VST algorithm for securing e-commerce, e-business, and web-based transaction applications. All WEB-key™ communication is triple-encrypted to prevent secure information from being intercepted over the Internet. Using WEB-key™'s browser plug-in, users enroll finger identification at a WEB-key™ enabled Web site from their own PC.

After enrollment, WEB-key™ requests finger identification every time a user begins a secure session. WEB-key™'s interface guides users through the few steps necessary to gain an accurate finger identification. The entire identification process takes less time than typing a user ID and password.

The Web based server authentication application is an integrated solution involving the distribution of readers and the licensing of client and server based software to provide for reliable and cost effective user authentication in connection with the processing of transactions over the Internet. This solution is intended to secure other Internet applications such as restricting access to specific Web pages, specific information contained on a Web-site or specific applications. We believe we have the opportunity to be the first supplier of a reliable electronic identification and authorization solution which operates effectively without the aid of a personal identification number or password supplied by the user.

Architecture. WEB-key™ provides an easy-to-use and secure method for granting users access via the Internet to proprietary information residing on remote servers.

WEB-key™ consists of three basic components:

•: finger print scanner
•: Vector Segment Technology processing software tightly and securely integrated with a web browser
•: identification database residing on a web server

The user simply logs-on a computer or application residing on a computer using their fingerprint. WEB-key™ processes a raster scan image which is enhanced using WEB- key™ software integrated into the web browser. The image enhancing employs a variety of proprietary techniques to improve accuracy and protect against spoofing. The WEB-key™ software then converts the enhanced image into a unique mathematical representation of the fingerprint using Vector Segment Technology. An encrypted print model is generated for transmission across the Internet to the central WEB-key™ registry. The WEB-key™ web server de-encrypts the mathematical model which operates as an index key for searching the database for a match. The web server matches the Vector Segment Technology BIO-key against a database of registered users to obtain a match. If a match is found, the user is allowed access to the protected content on a connected web server.

WEB-key™ provides a reliable and secure user authentication solution. WEB-key™ takes advantage of new security features in Microsoft's Internet Explorer versions 5.5 SP2 and 6.0, in addition to 1024 bit enhanced encryption capabilities integrated with public/private key pairs. WEB-key™ has also been integrated with Oracle9iRAC and 10g which offers advanced speed, scalability, and reliance to WEB-key™'s database tier. Additional tools and software based on VST technology are under development.

We do not currently manufacture any hardware and do not intend to in the future. We rely on OEMs, systems integrators and other licensees of our software to supply the necessary hardware, including optical readers. We have relationships with hardware manufacturers which enable us to supply readers as an integrated solution when necessary. Our technology includes proprietary open architecture communication software which allows virtually any reader to be integrated with our technology. Our software has been integrated with readers manufactured by Polaroid, Authentec, Ethentica, CrossMatch, ST Micro, Secugen, Fujitsu, TesTec, Silex, StarTek, Targus, and other independent manufactures.

PocketCop©. PocketCop© is a software solution that provides police officers and other security personnel instantaneous access to important criminal, civil and private database information in a wireless environment. PocketCop© is the first and only copyrighted handheld application that allows law enforcement officers to access state and federal databases over the wireless network for PalmOS,

Windows CE and PocketPC. With the use of a portable wireless handheld device and PocketCop© application software, an authorized user can access suspect information such as wanted status, warrant status, vehicle registration and driver license status. The highest available encryption methods are implemented to provide secured transactions between the handheld device and the local agency's server meeting and exceeding state and federal certification standards.

Aether Mobile Government. On September 30, 2004, we completed our acquisition of Aether Mobil Government. Aether Mobile Government provides wireless data solutions for use by public safety organizations, primarily state and local police, fire and rescue and emergency medical services organizations, that enable such organizations to access law enforcement databases to validate identities and obtain suspect information. Its public safety solutions are integrated into fifty (50) different state databases, as well as local and federal databases, and its products deliver real-time information in seconds, without the need for human dispatchers or other resources. Upon completing the purchase of Aether Mobile Government, we acquired its principal products, which are:

•: The PacketCluster® family of products, which are open, standards-based wireless information software products that provide police officers in the field with direct access to motor vehicle and warrant information and other critical information;
•: The handheld version of PacketCluster® Patrol™ (called PocketBlue™), which is a handheld application for mobile law enforcement that is part of a fully integrated mobile data system, providing criminal database queries, secure messaging and alarm capabilities for all connected mobile users;
•: PacketWriter™, which is a mobile field reporting solution that allows for mobile data collection, data sharing with PacketCluster® and work-flow management;
•: The FireRMS™ family of products for fire and rescue companies, which are compliant incident reporting products specifically developed to cut report completion time for front-line emergency response personnel; and
•: Handheld applications for fire and rescue companies (PocketFD™ and PocketCluster Rescue™), which allow fire services personnel to wirelessly access and update records in the field and extends computer aided dispatch, fire records management systems and other in-house data sources to a mobile environment.

Potential Market

The growth of electronic fingerprint identification will be driven by the need for secure access to private applications and proprietary databases residing on both private and public network infrastructures. The scope of these opportunities include:

•: corporations that increasingly rely upon the exchange and distribution of proprietary information among staff using intranet or other private networks
•: business-to-business e-commerce among trading partners which share confidential information on a secure basis
•: business-to-consumer e-commerce where the e-commerce service provider wants to restrict access to paying subscribers
•: Government Regulations such as HIPPA and Gramm Leach Bliley which are forcing the secure management of user identities
•: Application software providers that require secure access to applications such as Single Sign On, HR, ERP, Point of Sale, Check Cashing, and Medical Records

Although electronic commerce has many benefits, the geographical separation of buyers from sellers creates a significant problem arising from the opportunity for fraud. Firewall and encryption software address important aspects of security but do not address the fraud problem inherent in the potential anonymity of a remote user. Corporate intranets are an equally attractive and compelling market. Corporations increasingly rely upon intranet infrastructure for the dissemination of proprietary business data throughout an organization. Since access rights to different classes of data vary among employees, password identification and authorization is integral to all corporate networks.

The current solution to these issues is the association of passwords and PIN numbers with individuals. This solution requires employees or users to remember or retain a growing number of keys cards, passwords and PIN numbers and employers or Internet companies to periodically change passwords and PIN numbers to maintain their integrity. Since such information can be stolen or shared, they provide no assurance that the user is actually who they claim to be. WEB-key™ has been designed to address each of these concerns. We believe that augmenting or replacing traditional passwords presents a substantial market opportunity. Our technology could virtually replace and eliminate the need for passwords and the associated administrative costs while providing a higher assurance of identity security and user convenience. Government, aviation/transportation and enterprise security present significant additional opportunities.

We believe that our law enforcement and public safety division is well-positioned to help government agencies address certain aspects of ongoing homeland security concerns. The estimated potential includes nearly one million officers, supported by hundreds of thousands of vehicles across 18,000 agencies in the United States alone. Additionally the market opportunity for fire departments and EMS services is approximately 31,000 agencies and 75,000 vehicles. The Company's strategic partnerships with HP, Oracle, ChoicePoint, AutoDesk and Netegrity will extend the market reach of the combined companies after our anticipated acquisition of Aether Mobile Government.

Marketing and Distribution

Our marketing and distribution efforts consist of:

•: Developing strategic alliances with technology leaders such as Oracle, Netegrity, Hewlett Packard, Autodesk and others
•: Promoting biometric technology and our offerings through industry trade shows, public speaking engagements, press activities and partner marketing programs
•: Directing licensing efforts to, among others, original equipment manufacturers ("OEMs"), application developers and system integrators.
•: Building a reseller, integrator, partner network and a direct sales team

Direct Selling Efforts. Our current selling efforts are conducted primarily through our expanded direct sales organization. Our sales team consists of our vice president of sales, three area sales directors, a business integration manager to support sales efforts with partners, ISV's, OEM's and the indirect channel, and a senior sales support representative to support all direct and indirect sales campaigns.

Strategic Alliances and Partnerships. We attend and actively participate in various product conferences and conventions in the technology and security industries to generate market awareness of biometric technology generally, and our offerings specifically. During the past year, we have strengthened our alliance with Oracle having been recognized as Certified Partner in the Oracle Partner Network. We support the Oracle e-business suite of applications and provide the biometric enabler for the Oracle Single Sign on product. We are a development partner with Oracle which provides the underlying database used for true user identification and "on demand" alias checking. As

a development partner, we participate in Oracle Trade Shows such as Oracle Open World and Oracle Apps World.

We have formed alliances with other industry leaders. We are a Premier Partner of Netegrity, a leader in the identity management, whose Identity technology is used by over 800 corporate accounts with over 2.5 million users. We have developed a biometric interface allowing users of Netegrity to enhance the traditional methods of user identification, which we intend to aggressively market through the Netegrity Partner and Integrator Network. We are also working with Choicepoint, a leader in civil identification and background checks, to thwart identity theft in the commercial marketplace. One solution being deployed is a check cashing application where individuals would use fingerprint biometrics to truly verify that they are the individual carrying the credentials and authorized to conduct the transaction. Other solutions utilizing the strength of Choicepoint products and services are currently being developed.

We also have established, through PSG, a strategic marketing partnership with Hewlett Packard to provide PSG's technology to the Massachusetts State Police on a statewide basis.

Public and Private Sector. The events of September 11, 2001 have heightened the need for securing data dissemination throughout and between government agencies and automating the positive identification of personnel. We believe our finger identification technology coupled with the capabilities of our wireless data solutions and our alliance partners are the most advanced solutions capable of meeting these needs. In this regard, we were recently awarded a contract to ensure the secure access, transmission and retrieval of critical government and public sector information. We are also working with the National Sheriff's Association and the Pegasus Research Foundation to provide biometric authentication for secure sharing of critical data to Sheriff's offices and first responders across the country. We expect the initial rollout to grow from the initial 220 Sheriff's locations.

Licensing. We target both Internet infrastructure companies and large portal providers as licensees of our WEB-key solution. On the Internet infrastructure side, we seek to partner with Internet server manufacturers, providers of database and data warehouse engine software, horizontally positioned application engines, firewall solution providers and peripheral equipment manufacturers. On the portal side, we are targeting financial service providers such as credit and debit card authorization and issuing institutions, Internet retailers, business-to-business application service providers (ASPs) and corporate intranets. During 2003, we commenced a direct selling effort of WEB-key™ and VST and entered into license agreements with OEMs and system integrators to develop applications for distribution to their respective customers. We expect to continue to generate revenue during the remainder of 2004 from existing and new customer relationships.

We are also addressing the security needs of application providers in the following vertical markets:

•: Government: Northup Grumann has deployed a pilot within the Department of Defense to cross credential visitors and contractors to certain military bases using our technology.
•: Education: Educational Biometrics has incorporated our technology to enable school children to pay for school lunch programs and checkout library books using their fingerprints. VST technology enabled Educational Biometrics to easily enroll these children and reduce the time students spend in lunch line and administrative costs of managing passwords and collecting payments.
•: Healthcare: Biometric Technologies, a licensee in South Africa, is utilizing our technology to minimize fraud for health service providers. The integration of our biometric solution to truly identify individuals presenting insurance cards will reduce losses due to identity fraud.

•: Financial: We are working with several partners focusing on financial applications such as check cashing, point of sale systems and employee trusted identification cards, as well as customer facing applications over the internet.

Competition

The markets for our products and technologies are developing and are characterized by intense competition and rapid technological change. No assurance can be given that our competitors will not develop new or enhanced technologies that will offer superior price, performance or function features or render our products or technologies obsolete.

In addition to existing commonplace methods of restricting access to facilities such as pass cards, PIN numbers, passwords, locks and keys, there are numerous companies involved in the development, manufacture and marketing of fingerprint biometrics products to government, law enforcement and prison markets. These companies include, but are not limited to, PRINTRAK International, IDENTIX, and Bioscript.

Most current automated fingerprint identification product sales have been for government and law enforcement applications, which are typically priced higher than our products and licensing arrangements. Although most companies targeting consumer application markets have completed the development of their products, biometric products and technologies have not been widely accepted in the commercial markets. Most companies competing for commercial opportunities are in the business of selling scanning devices and tie their algorithm to a specific device. We have created a "device independent" algorithm that provides for flexibility in choosing the correct device, optical or tactile sense to fit the application served.

With current non-biometric technologies, the user must typically possess a key, card, or bit of information such as a PIN number or password. These systems are easily defeated by obtaining possession of the key, card, or password, or by counterfeiting the key or card. The Company's biometric technology is intended to replace such systems and substantially reduce the related security breaches. Although biometric based "verification" systems can identify a person and prevent unauthorized persons from entering into a restricted area, such systems do not eliminate the need for PIN numbers, cards, keys or tokens. By contrast, our identification technology typically does not require the use of any such additional identifier other than the person's fingerprint and "identifies" rather than "verifies" the subject. We believe that such end-user convenience creates a meaningful competitive advantage for the Company. There can be no assurance, however, that our competitors will not develop similar or superior "identification" technology, which could have a material adverse effect on our financial condition and results of operation. We will also be competing for market share with other biometric technologies including hand geometry, iris scanning, retinal scanning, and signature verification, as well as existing lock/security/card technology.

Our current and potential competitors for the products and services we currently offer through our Law Enforcement and Public Safety division, and those products that we plan to offer in the future, include mobile and/or wireless software companies such as Sybase, Inc., Motorola, Inc., Qualcomm, Inc., Minor Planet Systems USA Inc., and Terrion. Some of our existing and potential competitors have substantially greater financial, technical, marketing and distribution resources than we do. Furthermore, these competitors may be able to adopt more aggressive pricing policies and offer customers more attractive terms than we can.

Intellectual Property Rights

Our technology consists of knowledge and information relating to computer software and methods, which is used to create an automated process of capturing, processing, analysis and matching of a fingerprint for authorization purposes. Matching can be performed against existing databases or

individual samples. We have patent application claims on our algorithm technologies, called Vector Segment Technology, our authentication solutions security framework, called WEB-key™, our trusted device communication methodologies, and our secure template processes. There can be no assurance that any patents will be issued, or that, if issued, we will have the resources to protect any such issued patent infringement. Although we believe that its technology does not infringe upon patents held by others, no assurance can be given that such infringements do not exist.

Our technology consists of software. We take measures to ensure copyright and license protection for our software releases prior to distribution. Where possible, the software is licensed in an attempt to ensure that only licensed and activated software functions to its full potential. This provides a mechanism to combat cloning of products.

We believe we have developed common law trademark rights in the terms SACman™, SACcat™, SACremote™, BIO-key™, True User Identification™, WEB-key™ and PocketCop™ and have filed federal trademark applications. We do not claim any additional trademarks at this time. Pursuant to our purchase of Aether Mobile Government as described above, we have acquired the following additional trademarks that have been registered or published with or allowed by the Unites States Patent and Trademark Office: PacketWriter™, PacketCluster®, PacketCluster® Patrol™, Cerulean™ and Cerulean Design.

Research and Development

During fiscal years ended December 31, 2002 and 2003, we spent approximately $1,085,000 and approximately $1,037,000, respectively, on research and development. Our limited customer base did not directly bear these costs, which were principally funded through outside sources of equity and debt financing.

Although we believe that our identification technology is one of the most advanced and discriminating fingerprint technologies available on the market today, the markets in which we compete are characterized by rapid technological change and evolving standards. In order to maintain our position in the market, we will continue to upgrade and refine our existing technologies. During 2004, our research and development effort will be focused on the continued evolution of our Web based authentication solution, furthering the VST algorithm, SDK and Web-key. Our goal is to provide a full identification solution enabling the identification of individuals with a single finger scan, to a population of 1,000,000 prints on a standard Oracle platform in less than five seconds.

Government Regulation

We are not currently subject to direct regulation by any government agency, other than regulations generally applicable to businesses. However, in the event of any international sales, we would likely be subject to various domestic and foreign laws regulating such exports and export activities.

Environmental Regulation

As of the date of this prospectus, we have not incurred any material expenses relating to the compliance with federal, state or local environmental laws and do not expect to incur any material expenses in the foreseeable future.

Employees and Consultants

We currently employ one hundred fifteen (115) individuals on a full-time basis; seventy-one (71) in engineering, research and development, eleven (11) in finance and administration and thirty-three (33) in sales and marketing. We also utilize four (4) consultants who provide engineering and technical services and one (1) who provides financial consulting services. We anticipate retaining additional sales and marketing personnel within the next twelve (12) months to execute our business plan.

DESCRIPTION OF PROPERTY

We do not own any real estate. We conduct operations from the following leased premises:

•: Approximately 6,000 square feet of space located at 1285 Corporate Center Drive, Suite 175, Eagan, Minnesota, which is leased under a four-year lease, which terminates in August 2007 and currently provides for monthly rent of $2,842.

LEGAL PROCEEDINGS

Except as disclosed below, we are not a party to any material pending legal proceeding nor are we aware of any proceeding contemplated by any governmental authority involving the Company. In June 2003, PSG was named as a defendant in a civil action initiated in the Superior Court Department in Hampden County, Commonwealth of Massachusetts by The Vince Group, Inc. ("TVG"). The case has since been removed to the United States District Court for the District of Massachusetts at the request of the parties. The complaint claims that PSG is obligated to pay a percentage of certain of its revenues to TVG in consideration for a strategic business introduction allegedly made by an agent of TVG. PSG has denied the allegations and filed an answer in the litigation, and as of the date of this prospectus, the outcome of the litigation is pending. The claim is for an unspecified amount including actual damages, interest, and attorney's fees. Management believes that the claim is without merit and will be settled out of court for an amount that will not have a material adverse affect on our business, financial condition or operating results. In addition, the merger agreement pursuant to which we acquired PSG provides that any liability or payment obligation arising from this litigation will be solely the responsibility of the former shareholders of PSG.

The employment agreement also provides for an annual bonus of options to purchase up to 500,000 shares of Company common stock payable at the discretion of the Board of Directors.

The base salary has been adjusted to $216,000 for 2004. The quarterly performance bonus benchmarks for 2004 have also been adjusted to provide for payment of the $37,500 quarterly bonus upon achieving gross revenue of: $500,000, $750,000, $1,000,000 and $1,250,000 during the first, second, third and fourth calendar quarters of 2004, respectively. Additional performance bonuses of $50,000 upon achieving annual gross revenue of at least $4,000,000 and $50,000 upon the Company reporting operating profit during 2004 have also been included for 2004.

The employment agreement contains standard and customary confidentiality, non-solicitation and "work made for hire" provisions as well as a covenant not to compete which prohibits Mr. DePasquale from doing business with any current or prospective customer of the Company or engaging in a business competitive with that of the Company during the term of his employment and for the one year period thereafter. The agreement may be terminated by the Company at any time with or without cause. In the event of termination without cause, Mr. DePasquale shall continue to be paid his then current base salary

for the greater of six (6) months from the date of such termination or the number of months remaining until the end of the term of the employment agreement.

Harlan Plumley

In connection with his pending appointment as Chief Financial Officer of the Company as of November 1, 2004, we entered into a one (1) year employment agreement with Harlan Plumley. The employment agreement provides for an annual base salary of $190,000 and a performance bonus payable at the sole discretion of the Company. Unless terminated at least 30 days prior to the end of the term, the employment agreement automatically renews for successive one year terms. In the event that Mr. Plumley is terminated without cause, Mr. Plumley will receive severance payment equal to his base salary for the greater of 6 months and that number of months prior to the end of the term. The employment agreement contains standard and customary confidentiality, non-compete and work made for hire provisions.

Upon execution of the employment agreement, we issued Mr. Plumley a stock option to purchase 200,000 shares of our common stock at an exercise price of $1.05 per share, the last sale price of our common stock as reported on the OTC Bulletin Board on the date of grant. The option has a term of seven (7) years and vests in three equal annual installments commencing on September 15, 2005.

Kenneth S. Souza

In connection with his appointment as Senior Vice President and Chief Technology Officer of the Company on October 4, 2004, we entered into a one (1) year employment agreement with Kenneth S. Souza. The employment agreement provides for an annual base salary of $200,000 and a performance bonus in the amount of up to $76,000 payable upon achievement of certain performance criteria. Unless notice of non-renewal is provided to Mr. Souza at least two months prior to the end of the term, the employment agreement automatically renews for successive one year terms. In the event that Mr. Souza is terminated without cause, Mr. Souza will receive severance payment equal to his base salary for the greater of 6 months and that number of months remaining until the end of the term. The employment agreement contains standard and customary confidentiality, non-compete and work made for hire provisions.

Change in Control Provisions

The Company's 1996 Stock Option Plan (as amended to date, the "1996 Plan") and 1999 Stock Option Plan (the "1999 Plan" and together with the 1996 Plan, the "Plans")) each provide for the acceleration of the vesting of unvested options upon a "Change in Control" of the Company. A Change in Control is defined in the Plans to include (i) a sale or transfer of substantially all of the Company's assets; (ii) the dissolution or liquidation of the Company; (iii) a merger or consolidation to which the Company is a party and after which the prior shareholders of the Company hold less than fifty percent (50%) of the combined voting power of the surviving corporation's outstanding securities; (iv) the incumbent directors cease to constitute at least a majority of the Board of Directors; or (v) a change in control of the Company which would otherwise be reportable under Section 13 or 15(d) of the Exchange Act.

In the event of a "Change In Control" both Plans provide for the immediate vesting of all options issued thereunder. The 1999 Plan provides for the Company to deliver written notice to each optionee under the 1999 Plan fifteen (15) days prior to the occurrence of a Change In Control during which all options issued under the 1999 Plan may be exercised. Thereafter, all options issued under the 1999 Plan which are neither assumed nor substituted in connection with such transaction, automatically expire unless otherwise determined by the Board. The 1996 Plan provides for all options to remain exercisable for the remainder of their respective terms and permits the Company to make a cash payment to any or all optionees equal to the difference between the exercise price of any or all such options and the fair market value of the Company's common stock immediately prior to the Change In Control.

Options issued to executive officers outside of the Plans contain change in control provisions substantially similar to those contained in the 1999 Plan.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Employment Arrangements

The Company has entered into the employment agreements described above in the "EXECUTIVE COMPENSATION—Employment Agreements" section of this prospectus.

Options Granted to Executive Officers and Directors

During 2002, the Company issued options to purchase 200,000 shares of common stock to Thomas J. Colatosti upon his appointment as a director of the Company. During 2003, the Company issued options to purchase an aggregate of 2,180,000 shares of common stock to its officers and directors. The options were issued at exercise prices equal to the last sales price of the Company's common stock as reported on the OTC Bulletin Board on the date of grant, have terms of three (3) to seven (7) years, and vest over a one to three year period.

Consulting Arrangement with Thomas J. Colatosti

In connection with his appointment to the Board of Directors in September 2002, the Company entered into a consulting arrangement with Thomas J. Colatosti. Under the arrangement, the Company paid Mr. Colatosti $4,000 per month through December 2003 and issued him options to purchase 150,000 shares of common stock at an exercise price of $.33 per share, the closing price of the Company's common stock on the date of grant. In December 2003, a committee of independent directors renewed this arrangement through December 31, 2004. The committee also issued options to Mr. Colatosti to purchase 150,000 shares of common stock at an exercise price of $1.32 per share, the closing price of the Company's common stock on the date of grant, for serving as Chairman. Mr. Colatosti has substantial experience in the biometric industry and in addition to his role as the Chairman of the Board of Directors of the Company, provides extensive service to the Company in the areas of strategic planning and corporate finance.

In March 2004, Mr. Colatosti entered into a three-year consulting arrangement with The Shaar Fund Ltd., a principal creditor of the Company. Under the terms of the arrangement, The Shaar Fund transferred $375,000 principal amount of our secured convertible notes due October 1, 2005 to Mr. Colatosti. On April 29, 2004, Mr. Colatosti elected to convert the $375,000 principal amount of such note into 3,750 Series C Shares.

Consulting Agreement with Jeffry R. Brown

During the previous two fiscal years, Mr. Brown was the chief architect of the Company's strategic plan and the principal person involved in establishing and developing relationships with the Company's alliance partners, potential customers and other industry contacts which were important to the continued execution of the Company's business plan. In recognition of his continued service to the Company, the termination date of options to purchase 400,000 shares of common stock at $.20 per share previously issued to Mr. Brown was extended from March 31, 2003 until December 31, 2003.

The Company's 1999 Stock Option Plan (the "1999 Plan") was adopted by the Board of Directors of the Company on or about August 31, 1999. The material terms of the 1999 Plan are summarized below.

The 1999 Plan is currently administered by the Board of Directors of the Company (the "Plan Administrator"). The Plan Administrator is authorized to construe the 1999 Plan and any option issued under the 1999 Plan, select the persons to whom options may be granted, and determine the number of shares to be covered by any option, the exercise price, vesting schedule and other material terms of such option.

The 1999 Plan provides for the issuance of options to purchase up to 2,000,000 shares of common stock to officers, employees, directors and consultants of the Company at exercise prices not less than 85% of the last sale price of the Company's common stock as reported on the OTC Bulletin Board on the date of grant. Options have terms of not more than ten (10) years from the date of grant, are subject to vesting as determined by the Plan Administrator and are not transferable without the permission of the Company except by will or the laws of descent and distribution or pursuant to a domestic relations order. Options terminate three (3) months after termination of employment or other association with the Company or one (1) year after termination due to disability, death or retirement. In the event that termination of employment or association is for a cause, as that term is defined in the 1999 Plan, options terminate immediately upon such termination. The Plan Administrator has the discretion to extend options for up to three years from the date of termination or disassociation with the Company.

The 1999 Plan provides for the immediate vesting of all options in the event of a "Change In Control" of the Company. In the event of a Change In Control, the Company is required to deliver written notice to each optionee under the 1999 Plan fifteen (15) days prior to the occurrence of a Change in Control, during which time all options issued under 1999 Plan may be exercised. Thereafter, all options issued under the 1999 Plan which are neither assumed or substituted in connection with such transaction, automatically expire, unless otherwise determined by the Board. Under the 1999 Plan, a "Change In Control" is defined to include (i) a sale or transfer of substantially all of the Company's assets; (ii) the dissolution or liquidation of the Company; (iii) a merger or consolidation to which the Company is a party and after which the prior shareholders of the Company hold less than 50% of the combined voting power of the surviving corporation's outstanding securities; (iv) the incumbent directors cease to constitute at least a majority of the Board of Directors; or (v) a change in control of the Company which would otherwise be reportable under Section 13 or 15(d) of the Exchange Act.

As of December 31, 2003, there were outstanding options under the 1999 Plan to purchase 1,176,669 shares of common stock, and options to purchase an aggregate of 629,588 shares were available for future grants.

In addition to options issued under the 1999 Plan, the Company has issued options and warrants to employees, officers, directors and consultants to purchase an aggregate of 4,951,312 shares of common stock. The terms of these options are substantially similar to the provisions of the 1999 Plan and options issued thereunder.

DESCRIPTION OF SECURITIES

Common Stock

The Company is authorized to issue 85,000,000 shares of common stock, $.01 par value per share, of which 38,962,281 were outstanding as of October 25, 2004.

Holders of common stock have equal rights to receive dividends when, as and if declared by the Board of Directors, out of funds legally available therefor. Holders of common stock have one vote for each share held of record and do not have cumulative voting rights.

Holders of common stock are entitled, upon liquidation of the Company, to share ratably in the net assets available for distribution, subject to the rights, if any, of holders of any preferred stock then outstanding. Shares of common stock are not redeemable and have no preemptive or similar rights. All outstanding shares of common stock are fully paid and nonassessable.

Preferred Stock

Within the limits and restrictions provided in the Company's Articles of Incorporation, the Board of Directors has the authority, without further action by the shareholders, to issue up to 5,000,000 shares of preferred stock, $.01 par value per share, in one or more series, and to fix, as to any such series, any dividend rate, redemption price, preference on liquidation or dissolution, sinking fund terms, conversion rights, voting rights, and any other preference or special rights and qualifications.

Series B Convertible Preferred Stock. The Board of Directors has authorized the designation of 50,000 shares of preferred stock as Series B Convertible Preferred Stock (the "Series B Shares"), of which no shares are issued and outstanding. The material provisions of the Series B Shares are more fully set forth in the Certificate of Designation on file with the Minnesota Secretary of State.

Series C Convertible Preferred Stock. In March 2004, we designated 100,000 shares of preferred stock as Series C Convertible Preferred Stock (the "Series C Shares"), of which 72,182 are issued and outstanding. The following describes the material provisions of the Series C Shares which are more fully set forth in the Certificate of Designation on file with the Minnesota Secretary of State.

The Series C Shares accrue a cumulative annual dividend of 7% on the $100 face amount of such shares payable June 15 and December 15 each year in shares of common stock. In the event of a liquidation, dissolution or winding up of the Company, the Series C shares have a liquidation preference of $100 per share (plus all accrued and unpaid dividends thereon) prior to any payment or distribution to holders of our common stock. The Series C Shares are convertible into common stock at a conversion price of $.75 per share. The conversion price is subject to proportional adjustment in the event of stock splits, stock dividends or reclassifications. Subject to certain exceptions, in the event we issue additional shares of common stock at a purchase price less than the conversion price of the Series C Shares, the conversion price shall be lowered to such lesser price. In the event that the average closing bid price of our common stock is less than $1.00 per share for thirty (30) consecutive trading days at any time after March 3, 2007, we will be required to redeem the Series C Shares by payment of $100 per share plus all accrued and unpaid dividends due thereon.

We are required to obtain the consent of the holders of a majority of the Series C Shares in order to, among other things, issue any shares of preferred stock that are equal to or have a preference over the Series C shares or issue any shares of preferred stock, rights, options, warrants, or any other securities convertible into common stock of the Company, other than those issued to employees of the Company in the ordinary course of their employment or to consultants or other persons providing services to the Company so long as such issuances do not exceed 500,000 shares of common stock. We are also required to obtain such consent in order to, among other things, complete a sale or other

disposition of any material assets, complete an acquisition of a material amount of assets, engage in a merger, reorganization or consolidation, or incur or guaranty any indebtedness in excess of $50,000.

Dividend Policy

The Company has never paid cash dividends on its common stock. The Board of Directors does not anticipate paying cash dividends in the foreseeable future as it intends to retain future earnings, if any, to finance the growth of the business. The payment of future dividends will depend on such factors as earnings levels, anticipated capital requirements, the operating and financial condition of the Company and other factors deemed relevant by the Board of Directors.

Anti-Takeover Provisions of the Company's Articles of Incorporation

As described above, the Board of Directors is authorized without further stockholder action, to designate any number of series of preferred stock with such rights, preferences and designations as determined by the Board. Shares of preferred stock issued by the Board of Directors could be utilized, under certain circumstances, to make an attempt to gain control of the Company more difficult or time consuming. For example, shares of preferred stock could be issued with certain rights that might have the effect of diluting the percentage of common stock owned by a significant stockholder or issued to purchasers who might side with management in opposing a takeover bid that the Board of Directors determines is not in the best interest of the Company and its stockholders. The existence of the preferred stock may, therefore, be viewed as having possible anti-takeover effects.

Transfer Agent

The transfer agent for the Company's common stock is StockTrans, Inc., 44 West Lancaster Avenue, Ardmore, Pennsylvania 19003, (610) 649-7300.

ACQUISITION OF AETHER MOBILE GOVERNMENT

On September 30, 2004, we completed our acquisition from Aether of its Mobile Government Division. Pursuant to the Asset Purchase Agreement dated as of August 16, 2004 by and among the Company, Aether, Cerulean Technology, Inc. and SunPro, Inc., the Company paid Aether a purchase price of $10,000,000 in cash, subject to post-closing adjustments to reflect changes in Aether Mobile Government's working capital since June 30, 2004. In connection with this acquisition, the Company issued a Subordinated Secured Promissory Note to Aether in the face amount of $6,884,588 (the "Aether Note"). The Aether Note evidences a contingent reimbursement obligation of the Company to Aether and a surety fee payable by the Company to Aether, in each case with respect to a letter of credit maintained by Aether for the Company's benefit in connection with the acquisition. The Company's obligations under the Aether Note are secured by a security interest granted to Aether in all or substantially all of the Company's assets, subordinate to the security interest described in the "Convertible Debt Financing Transactions" section of this prospectus below.

•: The PacketCluster® family of products, which are open, standards-based wireless information software products that provide police officers in the field with direct access to motor vehicle and warrant information and other critical information;

•: The handheld version of PacketCluster® Patrol™ (called PocketBlue™), which is a handheld application for mobile law enforcement that is part of a fully integrated mobile data system, providing criminal database queries, secure messaging and alarm capabilities for all connected mobile users;

CONVERTIBLE DEBT FINANCING TRANSACTIONS

Secured Debt Financing

On September 29, 2004, we entered into a Securities Purchase Agreement (the "Senior Purchase Agreement") with Laurus Master Fund, Ltd. ("Laurus") and certain other institutional and accredited investors (together with Laurus, the "Senior Investors"). Under the Senior Purchase Agreement, the Company issued secured convertible term notes (the "Senior Convertible Notes") in the aggregate principal amount of $5,050,000, convertible into common stock of the Company in certain circumstances at $1.35 per share, and issued warrants (the "Senior Warrants") to purchase an aggregate of 1,122,222 shares of our common stock at an exercise price of $1.55 per share. The proceeds from this transaction were used in part to finance the Company's acquisition of Aether Mobile Government (the "Aether Acquisition"). The Company's obligations under the Senior Purchase Agreement, the Senior Convertible Notes and the Senior Warrants are secured by a security interest in all or substantially all of the Company's assets.

Under the terms of the Senior Convertible Notes, we are required to make monthly payments of accrued interest only beginning on November 1, 2004. In addition, the Senior Convertible Notes provide for monthly payments of principal in equal ¹/32 increments thereof, plus accrued interest, commencing February 1, 2005. The Senior Convertible Notes bear interest at an initial rate equal to the prime rate plus two percent (2%), subject to a six percent (6%) floor. The interest rate on the Senior Convertible Notes is subject to reduction on a month-by-month basis if specified conditions are met. In particular, if (a) we register the common stock underlying the Senior Convertible Notes and Senior Warrants on a registration statement declared effective by the Securities and Exchange Commission and (b) our common stock is trading at a 25% or greater premium to the note conversion price, then the interest rate will be adjusted downward by 2.0% for each incremental 25% increase over the note conversion price. Alternatively, if (x) we have not registered such common stock under an effective registration statement, but (y) our common stock is trading at a 25% or greater premium to the note conversion price, then the interest rate will be adjusted downward by 1.0% for each incremental 25% increase over the note conversion price.

For any cash payments we make on the Senior Convertible Notes (e.g., any amounts due that are not converted into common stock), we are required to pay an amount equal to 102% of the principal amount due. In addition, we can prepay the note at any time upon payment of an amount equal to 110% of the then outstanding principal balance, plus accrued and unpaid interest.

The Senior Investors have the option at any time to convert any or all of the outstanding principal and accrued and unpaid interest on the Senior Convertible Notes into shares of our common stock at a

conversion price of $1.35 per share. In addition, for each monthly payment under the note, the Senior Investors will be obligated to convert a portion of the monthly payment into common stock at the applicable conversion price, so long as:

•: the average closing price of our common stock (for the five trading days immediately preceding the payment date) is greater than $1.48 l per share (which represents 110% of the note conversion price, based on the initial conversion price of $1.35),
•: such amount being converted does not exceed 25% of the aggregate dollar trading volume for such immediately preceding twenty-two trading days, and
•: the shares of common stock underlying the note are registered under an effective registration statement with the Securities and Exchange Commission.

The terms of the Senior Convertible Notes and Senior Warrants prohibit conversion of the notes or exercise of the warrants to the extent that conversion of the notes and exercise of the warrants would result in any holder thereof, together with its affiliates, beneficially owning in excess of 4.99% of our outstanding shares of common stock. A holder may waive the 4.99% limitation upon 75 days' prior written notice to us. Also, this limitation does not preclude the holder from converting or exercising the note or warrant and selling shares underlying the note or warrant in stages over time where each stage does not cause the holder and its affiliates to beneficially own shares in excess of the limitation amount.

As security for our obligations to the Senior Investors, we, along with our wholly-owned subsidiary Public Safety Group, Inc. ("PSG"), granted to the Senior Investors a blanket security interest in all of our assets, and we entered into a stock pledge with the Senior Investors for the capital stock in PSG. If an event of default occurs under the Senior Convertible Notes or the other related investment agreements, 120% of the unpaid principal balance on the Senior Convertible Notes, plus accrued interest and fees, shall become immediately due and the Senior Investors shall be entitled to payment of a default interest rate of 1.5% per month on all amounts due under the Senior Convertible Notes. Such events of default include the following:

•: a failure to pay interest and principal payments under the Senior Convertible Notes within three days of when due;
•: a breach by us of any material covenant or term or condition of the Senior Convertible Notes or in any of the investment agreements, if not cured within 30 days of such breach;
•: a breach by us of any material representation or warranty made in the Senior Convertible Notes or in any of the investment agreements;
•: if we make an assignment for the benefit of our creditors, or a receiver or trustee is appointed for us, or any form of bankruptcy or insolvency proceeding is instituted by us, or any involuntary proceeding is instituted against us if not vacated within 60 days;
•: the filing of any money judgment or similar final process against us for more than $50,000, which remains unvacated, unbonded or unstayed for a period of 30 days;
•: if our common stock is suspended for five consecutive days or for five days during any ten consecutive days from a principal market or pursuant to a Securities and Exchange Commission stop order; and
•: a failure by us to timely deliver shares of common stock when due upon conversions of the Senior Convertible Notes.

Upon an event of default, the Senior Lenders will be entitled to specified remedies, including remedies under the Uniform Commercial Code.

We have agreed to register with the Securities and Exchange Commission for resale the shares of common stock that are issuable upon conversion of the Senior Convertible Notes and upon exercise of the Senior Warrants. Under the registration rights agreement, we are obligated to file a registration statement with the Securities and Exchange Commission on or before October 29, 2004, and to use reasonable commercial efforts to have the registration statement declared effective not later than December 28, 2004. The resale registration statement of which this prospectus is a part was filed with the Securities and Exchange Commission on October 29, 2004 for the shares underlying the Senior Convertible Notes and Senior Warrants. If we fail to comply with our registration obligations, the Senior Investors will be entitled to certain specified remedies, including monetary liquidated damages. In particular, for each 30 days (or such pro rated number of days) that we are out of compliance with our registration obligations, we will be subject to a liquidated damage assessment of 2% of the then outstanding principal amount of the Senior Convertible Notes.

Each Senior Investor has agreed, pursuant to the Senior Purchase Agreement, that neither it nor any of its affiliates and investment partners will (and will not cause any other person or entity, directly or indirectly, to) engage in "short sales" of our common stock for as long as any Senior Convertible Notes held by it remain outstanding. "Short sales" are contracts for the sale of shares of stock that the seller does not own, or certificates which are not within the seller's control, so as to be available for delivery at the time when, under applicable rules, delivery must be made.

Subordinated Debt Financing

On September 29, 2004, we entered into a Securities Purchase Agreement (the "Subordinated Purchase Agreement") with The Shaar Fund, Ltd. ("Shaar") and other existing shareholders of the Company and accredited investors (collectively, the "Subordinated Investors"). Under the Subordinated Purchase Agreement, the Company issued unsecured convertible term notes (the "Subordinated Convertible Notes") in the aggregate principal amount of $4,768,000, convertible into common stock of the Company in certain circumstances at $1.35 per share, and issued warrants (the "Subordinated Warrants") to purchase an aggregate of 1,059,553 shares of our common stock at an exercise price of $1.55 per share. The proceeds from this transaction were used in part to finance a portion of the Aether Acquisition and will be used in part for working capital purposes.

Under the terms of the Subordinated Convertible Notes, we are required to make monthly payments of accrued interest only beginning on November 1, 2004. In addition, the Subordinated Convertible Notes provide for monthly payments of principal in equal ¹/32 increments thereof, plus accrued interest, commencing February 1, 2005, which payments may be made in shares of common stock at the option of each noteholder. The Subordinated Convertible Notes bear interest at an initial rate equal to the prime rate plus seven and one-half percent (7.5%), subject to an eleven percent (11%) floor.

We may prepay the Subordinated Convertible Notes at any time upon payment of an amount equal to 110% of the then outstanding principal balance, plus accrued and unpaid interest. Upon any such prepayment, the Senior Convertible Notes must also be prepaid. The Subordinated Investors have the option at any time to convert any or all of the outstanding principal and accrued and unpaid interest on the Subordinated Convertible Notes into shares of our common stock at a conversion price of $1.35 per share.

The terms of the Subordinated Convertible Notes and Subordinated Warrants prohibit conversion of the notes or exercise of the warrants to the extent that conversion of the notes and exercise of the warrants would result in any holder thereof, together with its affiliates, beneficially owning in excess of 4.99% of our outstanding shares of common stock. A holder may waive the 4.99% limitation upon 75 days' prior written notice to us. Also, this limitation does not preclude the holder from converting or exercising the note or warrant and selling shares underlying the note or warrant in stages over time

where each stage does not cause the holder and its affiliates to beneficially own shares in excess of the limitation amount.

If an event of default occurs under the Subordinated Convertible Notes or the other related investment agreements, the unpaid principal balance on the Subordinated Convertible Notes, plus accrued interest, shall, at the noteholder's option, become immediately due and the Subordinated Investors shall be entitled to payment of additional default interest at the rate of 2.0% per month on all amounts due under the Subordinated Convertible Notes. Such events of default include the following:

•: failure to pay interest and principal payments under the Subordinated Convertible Notes within three days of when due;
•: a breach by us of any covenant, term or condition in any material respect of the Subordinated Convertible Notes or in any of the investment agreements, if not cured within 30 days of such breach;
•: any representation or warranty made in the Subordinated Convertible Notes or in any of the investment agreements being false or misleading in any material respect;
•: if we make an assignment for the benefit of our creditors, or a receiver or trustee is appointed for us, or any form of bankruptcy or insolvency proceeding is instituted by us, or any involuntary proceeding is instituted against us;
•: the filing of any money judgment or similar final process against us for more than $50,000, which remains unvacated, unbonded or unstayed for a period of 30 days;
•: if our common stock is suspended for five consecutive days or for five days during any ten consecutive days from a principal market or pursuant to a Securities and Exchange Commission stop order;
•: a failure by us to timely deliver shares of common stock when due upon conversions of the Subordinated Convertible Notes; and
•: a change in our controlling ownership.

Upon an event of default, the rights and remedies of the Subordinated Investors will be subordinate to those of the Senior Investors pursuant to a Subordination and Intercreditor Agreement dated as of September 30, 2004 by and among Laurus, as Collateral Agent, Shaar, as Purchaser Agent, Aether Systems, Inc., PSG and the Company

We have agreed to register with the Securities and Exchange Commission for resale the shares of common stock that are issuable upon conversion of the Subordinated Convertible Notes and upon exercise of the Subordinated Warrants. Under the registration rights agreement, we are obligated to file a registration statement with the Securities and Exchange Commission on or before October 29, 2004, and to use reasonable commercial efforts to have the registration statement declared effective not later than December 28, 2004. The resale registration statement of which this prospectus is a part was filed with the Securities and Exchange Commission on October 29, 2004 for the shares underlying the Subordinated Convertible Notes and Subordinated Warrants. If we fail to comply with our registration obligations, the Subordinated Investors will be entitled to certain specified remedies, including monetary liquidated damages. In particular, for each 30 days (or such pro rated number of days) that we are out of compliance with our registration obligations, we will be subject to a liquidated damage assessment of 2% of the then outstanding principal amount of the Subordinated Convertible Notes.

Each Subordinated Investor has agreed, pursuant to the Subordinated Purchase Agreement, that neither it nor any of its affiliates and investment partners will (and will not cause any other person or entity, directly or indirectly, to) engage in "short sales" of our common stock for as long as any Subordinated Convertible Notes held by it remain outstanding.

PLAN OF DISTRIBUTION

The selling security holders may, from time to time after the registration statement which includes this prospectus becomes effective, sell any or all of their shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These sales may be at fixed or negotiated prices. The selling security holders may use any one or more of the following methods when selling shares:

•: ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
•: block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;
•: purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
•: an exchange distribution in accordance with the rules of the applicable exchange;
•: privately negotiated transactions;
•: broker-dealers may agree with the selling security holders to sell a specified number of such shares at a stipulated price per share;
•: a combination of any such methods of sale; and
•: any other method permitted pursuant to applicable law.

The selling security holders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.

Laurus Master Fund, Ltd., The Shaar Fund Ltd. and the other selling security holders offering shares of our common stock under this prospectus upon conversion of our convertible term notes and accompanying warrants have each agreed, pursuant to the applicable securities purchase agreement with us, that neither it nor any of its affiliates and investment partners will (and will not cause any other person or entity, directly or indirectly, to) engage in "short sales" of our common stock for as long as such notes held by it remain outstanding. "Short sales" are contracts for the sale of shares of stock that the seller does not own, or certificates which are not within the seller's control, so as to be available for delivery at the time when, under applicable rules, delivery must be made.

Broker-dealers engaged by the selling security holders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The selling security holders do not expect these commissions and discounts to exceed what is customary in the types of transactions involved. Any profits on the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, attributable to the sale of shares will be borne by a selling security holder. The selling security holders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on that person under the Securities Act.

In order to comply with the securities laws of certain states, if applicable, the shares being offered hereby must be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states such shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and there has been compliance thereof.

The selling security holders may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock

from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling security holders to include the pledgee, transferee or other successors in interest as selling security holders under this prospectus.

The selling security holders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus and may sell the shares of common stock from time to time under this prospectus after we have filed an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling security holders to include the pledgee, transferee or other successors in interest as selling security holders under this prospectus.

The selling security holders and any broker-dealers or agents that are involved in selling the shares of common stock may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares of common stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We are required to pay all fees and expenses incident to the registration of the shares of common stock. We have agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. The selling security holders will be responsible, however, for all selling commissions applicable to the sale of shares pursuant to this prospectus.

Each selling security holder that is an affiliate of a registered broker-dealer has represented to us that it purchased our securities for its own account for investment only and that at the time of such purchase, such selling security holder had no agreements, plans or understandings, directly or indirectly, with any person to distribute such securities.

The selling security holders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their shares of common stock, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares of common stock by any selling security holder. If we are notified by any selling security holder that any material arrangement has been entered into with a broker-dealer for the sale of shares of common stock, if required, we will file a supplement to this prospectus. If the selling security holders use this prospectus for any sale of the shares of common stock, they will be subject to the prospectus delivery requirements of the Securities Act.

The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of our common stock and activities of the selling security holders. We have informed the selling security holders that, during such time as they may be engaged in a distribution of any of the shares we are registering by this registration statement, they are required to comply with Regulation M, and the selling security holders have agreed, and will cause each of their affiliates and investment partners, to comply with Regulation M in all respects during such time. In general, Regulation M precludes any selling security holder, any affiliated purchasers and any broker-dealer or other person who participates in a distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase, any security which is the subject of the distribution until the entire distribution is complete. Regulation M defines a "distribution" as an offering of securities that is distinguished from ordinary trading activities by the magnitude of the offering and the presence of special selling efforts and selling methods. Regulation M also defines a "distribution participant" as an underwriter, prospective underwriter, broker, dealer or other person who has agreed to participate or who is participating in a distribution.

Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security, except as specifically permitted by Rule 104 of Regulation M. These stabilizing transactions may cause the price of our common stock to be more than it would otherwise be in the absence of these transactions. We have informed the selling security holders that stabilizing transactions permitted by Regulation M allow bids to purchase our common stock if the stabilizing bids do not exceed a specified maximum, and the selling security holders have agreed, and will cause each of their affiliates and investment partners, to comply with Regulation M in all respects during such time as they may be engaged in a distribution of any of the shares we are registering by this registration statement. Regulation M specifically prohibits stabilizing that is the result of fraudulent, manipulative or deceptive practices. Selling security holders and distribution participants are required to consult with their own legal counsel to ensure compliance with Regulation M.

DISCLOSURE OF COMMISSION POSITION OF INDEMNIFICATION
FOR SECURITIES ACT LIABILITIES

The Company's Articles of Incorporation limit the personal liability of the Company's officers and directors for monetary damages for breach of their fiduciary duty as directors, except for liability that cannot be eliminated under the Minnesota Business Corporation Act (the "MBCA"). The Company's Bylaws also provide for the Company to indemnify directors and officers to the fullest extent permitted by the MBCA.

The indemnification provisions described above would provide coverage for claims arising under the Securities Act and the Exchange Act. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the Company's Articles of Incorporation, Bylaws, the MBCA, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Report of Independent Certified Public Accountants

Board of Directors and Stockholders
BIO-key International, Inc.

We have audited the accompanying balance sheet of BIO-key International, Inc. as of December 31, 2003 and the related statements of operations, stockholders' equity (deficit) and cash flows for each of the two years in the two year period ended December 31, 2003. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of BIO-key International, Inc. as of December 31, 2003, and the results of its operations and its cash flows for each of the two years in the two year period ended December 31, 2003, in conformity with accounting principles generally accepted in the United States.

In our previous audit report on these financial statements dated March 25, 2004, we referred to several issues that raised substantial doubt about the Company's ability to continue as a going concern. However, as disclosed in Note A, the Company has entered into a significant financing arrangement which removed the substantial doubt about the Company's ability to continue as a going concern.

NOTES TO THE FINANCIAL STATEMENTS

December 31, 2002 and 2003

NOTE A—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Change in name of Company

In February 2002, the Company's shareholders approved the change in the Company's name from SAC Technologies, Inc. to BIO-key International, Inc.

Nature of Business

BIO-key International, Inc. (the Company) incorporated on January 7, 1993 with operations in Minneapolis, Minnesota. The Company's goal is to develop and market advanced biometric fingerprint technology solutions that provide fast, easy and highly secure personal identification for online access to computers and networks. The Company's fingerprint identification techniques can be used without the aid of a personal identification number. The Company's target market includes Internet application service providers, Internet based retailers and other operators of private networks, and entities where security and identification applications are required.

On March 30, 2004, the Company acquired all of the outstanding capital stock of Public Safety Group, Inc. (PSG), a privately-held company based in Winter Park, Florida. The acquisition was completed pursuant to the terms of an Agreement and Plan of Merger (the Merger Agreement) by and among the Company, BIO-key Acquisition Corp., a wholly-owned subsidiary of the Company, PSG and all of the shareholders of PSG. As a result of this transaction, PSG became a wholly-owned subsidiary of the Company and now constitutes a division of our business specializing in the law enforcement and public safety markets (the Public Safety Division).

Basis of Presentation

Broad commercial acceptance of the Company's technology is critical to the Company's success and ability to generate revenues. The Company has had no significant revenues to date, and has accumulated losses during the past two years of approximately $7,846,000, of which approximately $3,826,000 was incurred during 2003. As of December 31, 2003, there was a stockholders' deficit of approximately $9,136,000.

As of December 31, 2003, the Company was in need of substantial additional capital. The Company was considering various alternatives related to raising additional capital including continued funding from an investment group and new funding from other sources. No assurance could be given at that date that any form of additional funding would be available on terms acceptable to the Company, that adequate funding would be obtained to meet its needs, or that such funding would not be dilutive to existing stockholders.

On March 31, 2004, substantial doubt about the Company's ability to continue as a going concern was alleviated when 8,888,928 shares of the Company's common stock were sold for approximately $12,000,000 in gross proceeds.

The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States, which contemplate continuation of the Company as a going concern. The matter described in the preceding paragraph removed substantial doubt about the Company's ability to continue as a going concern.

Summary of Significant Accounting Policies

A summary of the significant accounting policies consistently applied in the preparation of the accompanying financial statements follows:

1. Revenue Recognition

Revenue from software licensing is recognized in accordance with Statement of Position (SOP) No. 97-2, Software Revenue Recognition, as amended by SOP No. 98-9. Accordingly, revenue from software licensing is recognized when all of the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is probable.

The Company intends to enter into arrangements with end users for items which may include software license fees, usage fees and services or various combinations thereof. For each arrangement, revenue will be recognized when evidence of an agreement has been documented, the fee is fixed or determinable, collection is probable, delivery of the product has occurred and no other significant obligation remains.

Multiple-Element Arrangements: For multiple-element arrangements, each element of the arrangement will be analyzed and the Company will allocate a portion of the total fee under the arrangement to the elements using vendor specific objective evidence of fair value of the element, regardless of any separate prices stated within the contract for each element. Vendor specific objective evidence is based on the price the customer is required to pay when the element is sold separately (i.e., software license fees charged when consulting or other services are not provided, hourly rates charged for consulting services when sold separately from a software license or usage fees). If vendor specific objective evidence of fair value does not exist for any undelivered elements, all revenue is deferred and recognized ratably over the service period if the undelivered element is services, or until sufficient objective evidence of fair value exists or all elements have been delivered.

License Revenue: Amounts allocated to license revenues is recognized at the time of delivery of the software and all other revenue recognition criteria discussed above have been met.

Service Revenue: Revenue from services is comprised of consulting and implementation services. Consulting services are generally sold on a time-and-materials basis and include a range of services including installation of software and assisting in the design of interfaces to allow the software to operate in customized environments. Services are generally separable from other elements under the arrangement since performance of the services are not essential to the functionality of any other element of the transaction and are described in the contract such that the total price of the arrangement would be expected to vary as the result of the inclusion or exclusion of the services. Revenue from services is generally recognized as the services are performed.

Usage Fee: A usage fee is charged on certain applications based on the customer's volume of use. Usage fees are recognized based on the actual level of use by the customer or, in the case of fixed-fee arrangements, ratably over the arranged time period.

F-8

The Company provides customers, free of charge or at a minimal cost, testing kits which potential licensing customers may use to test compatibility/acceptance of the Company's technology with the customer's intended applications.

2. Cash and Cash Equivalents

Cash equivalents consist of certificates of deposit and all other liquid investments with original maturities of three months or less. The Company maintains its cash balances in a financial institution in Nevada. These balances are insured by the Federal Deposit Insurance Corporation up to $100,000.

3. Accounts Receivable

Accounts receivable are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer's financial condition, credit history, and current economic conditions. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received.

4. Equipment, Furniture and Fixtures

Equipment, furniture and fixtures are stated at cost. Depreciation is provided for in amounts sufficient to relate the cost of depreciable assets to operations over their estimated services lives of three and five years using the straight-line method. Equipment, furniture and fixtures consisted of the following:

Equipment	$	66,543
Furniture and fixtures		36,550

		103,093
Less accumulated depreciation		42,936

	$	60,157

5. Long-lived Assets

The Company periodically evaluates the net realizable value of long-lived assets, including equipment, furniture and fixtures relying on a number of factors including operating results, business plans and economic projections and anticipated future cash flows. An impairment in the carrying value of an asset is recognized when the fair value of the asset is less than its carrying value. There was no impairment of long-lived assets during 2003 or 2002.

6. Advertising Expense

The Company expenses the costs of advertising as incurred. Advertising expense for the years ended December 31, 2002 and 2003 was approximately $6,000 and $18,000, respectively.

F-9

7. Research and Development Expenditures

All costs related to development of new products are charged to expense as incurred. Such costs are required to be expensed until technological feasibility and proven marketability of the product are established.

8. Basic and Diluted Loss per Common Share

Basic and diluted loss per common share for all periods presented is computed using the weighted average number of common shares outstanding. Basic weighted average shares outstanding include only outstanding common shares. Shares reserved for outstanding warrants, stock options or convertible preferred stock are not considered because the impact of the incremental shares is antidilutive.

9. Income Taxes

The Company provides for income taxes based on income reported for financial reporting purposes. Certain charges to earnings differ as to timing from those deducted for tax purposes; these relate primarily to net operating loss carryforwards. The tax effect of these differences is recorded as deferred income taxes.

10. Accounting for Stock-Based Compensation

In December 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure. SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 requires expanded and more prominent disclosure in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported results.

The Company has not adopted a method under SFAS No. 148 to expense stock options but rather continues to apply the recognition and measurement provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for those plans. No stock-based employee compensation expense for options is reflected in net income for the fiscal years presented as all options granted under those plans had an exercise price equal to the market value of the underlying common stock at the date of grant. A pro forma effect table is presented in the Pro Forma Compensation Disclosure section of Note K, which assumes the fair value recognition provisions of SFAS No. 123 would have been adopted for all options granted.

In the future, if employees exercise certain nonstatutory stock options, the Company may realize a tax benefit equal to the tax effect on the difference between the strike price of the option and the fair market value of the stock on the day of exercise. Tax benefits realized, if any, by the Company will be credited to additional paid-in capital. Similar accounting treatment is also given to any tax benefits the Company may realize arising from employees making disqualifying dispositions of incentive stock options.

F-10

11. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues and expenses during the reporting period, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Significant estimates are made for such items as valuation of deferred income taxes, conversion features of convertible debentures and preferred stock, and stock options and warrants outstanding.

NOTE B—PREPAID EXPENSES

Prepaid expenses consisted of the following:

Consulting fees	$	90,000
Insurance		42,181
Other		33,748

	$	165,929

In October 2003, the Company entered into a consulting agreement with a financial advisory services company. The terms of the agreement required $108,000 to be paid in fees. The prepaid fees were charged to operations during the first quarter of 2004 when the consulting services were provided in full.

NOTE C—OTHER ASSETS

Other assets consisted of the following:

Deferred offering costs	$	81,900
Patents pending		68,306

	$	150,206

Deferred Offering Costs

In March 2002, the Company engaged an investment banking firm to advise the Company regarding raising additional capital through the potential future issuance of the Company's equity, debt or convertible securities. The Company paid a nonrefundable retainer fee of $50,000, out of pocket expenses of $14,900 and granted a four year warrant to purchase 25,000 shares of the Company's common stock at an exercise price of $1.00 per share. The estimated value of the warrant at date of grant was $17,000. These deferred costs were charged to operations in the quarter ending March 31, 2004, when this engagement terminated.

F-11

NOTE D—ACCRUED LIABILITIES

Accrued liabilities consisted of the following:

Compensation	$	167,859
Other		5,877

	$	173,736

NOTE E—LONG-TERM OBLIGATIONS

Long-term obligations consisted of the following:

10% secured convertible note issued in 2001	$	3,617,920
10% secured convertible notes issued in 2002		1,080,000

7% secured convertible notes issued in 2003		3,852,250
Accrued interest		1,131,053

	$	10,431,223

A summary of the Company's long-term notes and debentures are as follows:

•: 10% Secured Convertible Note Issued in 2001: During 2001, the Company had unsecured short-term notes from the Investor in the aggregate principal amount of $2,770,000. The Investor converted this amount and associated accrued interest of $257,920 together with additional financing of $1,065,000 into a convertible note in the principal amount of $4,092,920 (the Convertible Note). During 2003, the Investor converted $475,000 of this note along with accrued interest of $98,465 into 764,620 shares of the Company's common stock at the stipulated per share conversion price of $0.75 per share. The Convertible Note, as amended, is due October 1, 2005 along with accrued interest at 10% per annum. The note is collateralized by substantially all of the Company's assets.

During the first quarter ending March 31, 2004, the Investor converted $2,063,938 of this note into shares of the Company's common stock at the stipulated per share conversion price of $0.75 per share.

During March 2004, the Company entered into a securities exchange agreement (the Agreement) with the Investor. Pursuant to the Agreement, the Investor converted the remaining $1,553,982 of this note into shares of the Company's series C convertible preferred stock at the stipulated per share conversion price of $100 per share.

In conjunction with the issuance of the Convertible Note, the Company issued a warrant to the Investor to purchase 4,000,000 shares of common stock at $1.00 per share through November 26, 2006. The Convertible Note was recorded net of a $1,016,000 discount assigned to the fair value of the warrant. The value assigned to the warrant was amortized as interest expense over the twenty-two month life of the Convertible Note. The fair value assigned to the warrant was estimated on the grant date using the Black-Scholes pricing model. The assumptions used to determine the fair value of the grant included the following assumptions: risk-free interest rate

F-12

of 3.5%, expected life of three years, stock price volatility of 175%, and expected dividends of zero.

•: Zero Interest Convertible Debenture: During 2000 and 2001, the Company had accrued penalties under a previous registration rights agreement with the Investor in the amount of $1,300,250. In 2001, the Investor agreed to reduce the penalty by $300,250 and converted the balance into a convertible debenture in the principal amount of $1,000,000. During 2003, the Investor converted this debenture into 1,333,333 shares of the Company's common stock at the stipulated per share conversion price of $0.75 per share.
•: 5% Convertible Note: During 2001, a convertible note in the principal amount of $539,625 was issued in exchange for the cancellation of an outstanding 5% debenture in the principal amount of $418,000 plus accrued interest of $121,625. During 2001 and 2002 this note was converted into shares of the Company's common stock at the stipulated per share conversion price equal to a 22% discount to the average of the closing price of the common stock for the five days preceding conversion. This convertible note was recorded net of a $113,000 discount assigned to the fair value of the beneficial conversion feature. This discount was amortized as interest expense when the debt was converted to common stock.
•: 10% Secured Convertible Notes Issued in 2002: As part of a recapitalization transaction, the Investor agreed to provide additional financing in incremental monthly installments during the six-month period commencing March 1, 2002, subject to certain conditions. As of December 31, 2002, the Company has received $1,080,000 and issued notes payable to the Investor. The notes, as amended, are due October 1, 2005 along with accrued interest at 10% per annum. The notes are convertible into shares of the Company's common stock at a conversion price of $0.75 per share. The notes are collateralized by substantially all of the Company's assets.

Pursuant to the Agreement entered into on March 31, 2004, the Investor converted $1,080,000 of this note into shares of the Company's series C convertible preferred stock at the stipulated per share conversion price of $100 per share.

•: 7% Convertible Notes Issued in 2002: As part of an August 2002 bridge note agreement with the Investor, the Investor has provided a total of $750,000 of additional financing in incremental monthly installments during the four-month period commencing August 2002, and issued the corresponding notes payable to the Investor. The note, as amended, is due October 1, 2005 along with accrued interest at 7% per annum. The bridge notes are convertible at the option of the Investor into shares of the Company's common stock at a conversion price of $0.75 per share or into shares of the Company's series B preferred stock at a conversion price of $100 per share. The note is collateralized by substantially all of the Company's assets.

Pursuant to the Agreement entered into on March 31, 2004, the Investor converted $750,000 of this note into shares of the Company's series C convertible preferred stock at the stipulated per share conversion price of $100 per share.

•: 7% Secured Convertible Notes Issued in 2003: In January 2003, the Investor agreed to provide up to $2,350,000 of new debt financing. The agreement was amended in October 2003 to provide for up to $2,500,000 of additional funding. As of December 31, 2003, the Company had received

F-13

advances totaling $3,852,250. Pursuant to this agreement, the Investor shall provide the additional monthly borrowings during 2004, subject to certain conditions. The terms of the notes, as amended December 31, 2003, require the principal and accrued interest at 7% to be repaid on October 1, 2005. In the event that the Company completes a private placement of equity securities resulting in gross proceeds of at least $5,000,000 on or before June 30, 2004 the principal amount and accrued interest due under the note is convertible, at the option of the Investor, into the securities sold in such transaction at a conversion price equal to the sale price of such securities. Upon completion of such an equity transaction, the Investor also has the right to request repayment of the note. The Investor may, at any time, elect to convert some or all of the notes into shares of the Company's common stock at a conversion price of $0.75 per share or into shares of the Company's series B preferred stock at a conversion price of $100 per share. The notes are collateralized by substantially all of the Company's assets. The terms of a Registration Rights Agreement with the Investor, as amended, require the Company to file a registration statement with the SEC covering the resale of any shares of common stock issuable upon any conversion of these notes. This registration statement shall be required to be filed sixty days after the date on which the Investor provides written notice to the Company of its demand that such a registration be filed.

In March 2004, at the request of the Investor, the Company issued Thomas J. Colatosti, the chairman of the Board, a $375,000 note and the Investor (collectively the Investors) a $2,125,000 note in exchange for the October 31, 2003, $2,500,000 7% Secured Convertible Promissory Note due the Investor. The terms of the notes require the principal and accrued interest at 7% to be repaid on October 1, 2005. In the event that the Company completes a private placement of equity securities resulting in gross proceeds of at least $5,000,000 on or before June 30, 2004 the principal amount and accrued interest due under the notes are convertible, at the option of the Investors, into the securities sold in such transaction at a conversion price equal to the sale price of such securities. Upon completion of such an equity transaction, the Investors also have the right to request repayment of the note. The Investors may, at any time, elect to convert some or all of the notes into shares of the Company's common stock at a conversion price of $0.75 per share or into shares of the Company's series C preferred stock at a conversion price of $100 per share.

Pursuant to the Agreement entered into on March 31, 2004, the Investor converted $2,352,250 of this note into shares of the Company's series C convertible preferred stock at the stipulated per share conversion price of $100 per share.

NOTE G—STOCKHOLDERS' EQUITY

Increase in Authorized Shares of Common Stock

In February 2002, the Company's shareholders approved amendments to its articles of incorporation which increased the number of authorized shares of common stock from 20,000,000 to 60,000,000.

Series B 9% Convertible Preferred Stock

The Series B Preferred Stock accrues dividends of 9% payable semi-annually on June 15, December 15, and on such date that the preferred stockholder elects to convert preferred stock to common stock, in cash, or at the option of the Company, in additional shares of its common stock. As of December 31, 2003, cumulative dividends in arrears were approximately $86,000. The Series B shares are redeemable at the option of the Company, so long as the Company's common stock is eligible for quotation on the OTC Bulletin Board and the shares issuable upon conversion are subject to an effective registration statement. The Series B shares are convertible into shares of the Company's common stock at a per share conversion price equal to the lesser of $0.75 or a 22% discount to the average closing price of the common stock during the five trading days preceding conversion. The Series B shares have no voting rights.

Series C 7% Convertible Preferred Stock

In March 2004, we designated 100,000 shares of preferred stock as Series C Convertible Preferred Stock (the "Series C Shares"). The Series C Shares accrue a cumulative annual dividend of 7% on the $100 face amount of such shares payable June 15 and December 15 each year in shares of common stock. In the event of a liquidation, dissolution or winding up of the Company, the Series C shares have a liquidation preference of $100 per share plus all accrued dividends thereon prior to any payment or distribution to holders of our common stock. The Series C Shares are convertible into common stock at a conversion price of $.75 per share. The conversion price is subject to proportional adjustment in the event of stock splits, stock dividends or reclassifications. Subject to certain exceptions, in the event we issue additional shares of common stock at a purchase price less than the conversion price of the Series C Shares, the conversion price shall be lowered to such lesser price. In the event that the trading price of our common stock is less than $1.00 per share for thirty (30) consecutive trading days at any time after March 3, 2007, we will be required to redeem the Series C shares by payment of $100 per share plus all accrued and unpaid dividends due thereon. We are required to obtain the consent of the holders of a majority of the Series C Shares in order to among other things, issue any shares of preferred stock, rights, options, warrants, or any other securities convertible into common stock of the Company, other than those issued to employees of the Company in the ordinary course of their employment or to consultants or other persons providing services to the Company so long as such issuances do not exceed 500,000 shares of common stock.

NOTE H—STOCK-BASED COMPENSATION

1996 Stock Option Plan

The fair value of each option grant is estimated as of the date of the grant using the Black-Scholes option-pricing model utilizing the same assumptions presented in the proforma compensation disclosure section below.

Options were granted to consultants and strategic partners during 2002 and 2003 totaling 350,000 and 5,000 shares, respectively. The estimated fair value of the options granted to consultants and strategic partners which vested in 2003 and 2002 were $0 and $100,000, respectively.

F-18

Proforma Compensation Disclosure

In December 2002, the Financial Accounting Standards Board (FASB) issued SFASB No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure, SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary charge to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 requires expanded and more prominent disclosure in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported results.

The Company has not adopted a method under SFAS No. 148 to expense stock options but rather continues to apply the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock issued to Employees, and related interpretations in accounting for those plans. No stock-based employee compensation expense for options is reflected in net earnings for the fiscal periods presented as all options granted under those plans had an exercise price equal to or higher than the market price of the underlying common stock at the date of grant.

If compensation expense for the stock options granted had been determined based on the fair value at the grant dates consistent with the method of SFAS No. 123, the Company's proforma net loss and proforma loss per share would have been as follows:

		2002			2003
Net loss
	As reported	$	(4,019,974	)	$	(3,826,073	)
	Proforma		(4,166,974	)		(3,962,073	)
Loss applicable to common stockholders
	As reported	$	(4,184,939	)	$	(3,962,828	)
	Proforma		(4,331,939	)		(4,098,828	)
Basic and diluted loss per common share
	As reported	$	(.32	)	$	(.23	)
	Proforma		(.33	)		(.23	)

In determining the proforma compensation cost of the options granted, the fair value of each grant was estimated on the date of grant using the Black-Scholes option pricing model. The assumptions used to determine the fair value of each grant included the following weighted average assumptions:

	2002		2003
Risk free interest rate	2.54	%	1.90	%
Expected life of options (in years)	5.00		3.00
Expected dividends	—		—
Volatility of stock price	154	%	120	%

NOTE I—INCOME TAXES

Deferred taxes are due to income tax credits and net operating loss carryforwards, and to the temporary differences between the carrying values of certain assets and liabilities for financial reporting

F-19

and income tax purposes. Significant components of deferred taxes are as follows at December 31, 2003:

Current asset:
	Accrued compensation	$	20,000
Non-current asset:
	Accrued interest and other		396,000
	Income tax credits		166,000
	Net operating loss carryforwards		9,070,000
Valuation allowances			(9,652,000	)

		$	-

A valuation allowance equal to the full amount of the deferred tax asset has been recorded due to the uncertainty of realization of the deferred tax assets due to operating loss history of the Company. The valuation allowance could be reduced or eliminated based on future earnings and future estimates of taxable income. Similarly, income tax benefits related to stock options exercised have not been recognized in the financial statements.

The Company has federal and Minnesota net operating loss carryforwards of approximately $24,504,000 and $12,406,000, respectively, as of December 31, 2003. These operating losses expire between 2011 and 2023. Net operating loss carryforwards will be subject to the limitations under Section 382 of the Internal Revenue Code due to changes in the equity ownership of the Company.

NOTE J—FAIR VALUES OF FINANCIAL INSTRUMENTS

The Statement of Financial Accounting Standards Board No. 107 "Disclosures about Fair Value of Financial Instruments" (SFAS 107) requires disclosure of the estimated fair value of an entity's financial instruments. Such disclosures, which pertain to the Company's financial instruments, do not purport to represent the aggregate net fair value of the Company. At December 31, 2003, the carrying value of all material financial instruments, for which it is practicable to estimate the fair value, approximated fair value because of the short maturity of those instruments.

NOTES TO FINANCIAL STATEMENTS

December 31, 2003, and June 30, 2004

(Unaudited)

1. Unaudited Statements

The accompanying unaudited interim consolidated financial statements include the accounts of BIO-key International, Inc. and their wholly owned subsidiary (collectively, the Company) and are stated in conformity with accounting principles generally accepted in the United States, pursuant to the rules and regulations of the Securities and Exchange Commission. Pursuant to such rules and regulations, certain financial information and footnote disclosures normally included in the financial statements have been condensed or omitted. Significant intercompany accounts and transactions have been eliminated in consolidation.

In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all necessary adjustments, consisting only of those of a recurring nature, and disclosures to present fairly the financial position and the results of its operations and cash flows for the periods presented. It is suggested that these interim consolidated financial statements are read in conjunction with the financial statements and the related notes thereto included in the Company's Annual Report on Form 10-KSB for the fiscal year ended December 31, 2003.

2. Liquidity and Capital Resource Matters

Broad commercial acceptance of the Company's technology is critical to the Company's success and ability to generate revenues. The Company has accumulated losses during the last two years and through the second quarter of 2004 of approximately ($10,019,000) of which approximately ($2,173,000) was incurred during 2004. As of June 30, 2004 stockholders' equity was approximately $14,970,000.

On March 31, 2004 substantial doubt about the Company's ability to continue as a going concern was alleviated when 8,888,928 shares of the Company's common stock were sold for approximately $12,000,000 in gross proceeds.

The accompanying financial statements have been prepared in conformity with accounting principles generally accepted in the United States, which contemplate continuation of the Company as a going concern. The matters described in the preceding paragraph removed substantial doubt about the Company's ability to continue as a going concern.

3. Loss per Common Share

Basic loss per share is calculated by dividing the net loss attributable to common stockholders by the number of weighted average common shares outstanding. Diluted earnings per share are calculated by dividing the net loss attributable to common stockholders by the weighted average common shares, and when dilutive, by including options, warrants and convertible securities outstanding using the treasury stock method. There was no difference between basic and diluted loss per share for all periods presented, because the impact of including options, warrants and convertible securities would be antidilutive.

4. Marketable Debt Securities

Debt and equity securities designated as available-for-sale, whose fair values are readily determinable, are carried at fair value with unrealized gains or losses included as a component of

F-25

accumulated other comprehensive income, net of applicable taxes. Debt and equity securities classified as trading securities are carried at fair value with unrealized gains or losses included in income. Debt securities that are expected to be held-to-maturity are carried at amortized cost. Individual securities classified as either available-for-sale or held-to-maturity are reduced to net realizable value by a charge to income for other than temporary declines in fair value. Realized gains and losses are determined on the average cost method and are reflected in income. As of June 30, 2004, the Company's investments are all classified as held-to-maturity securities and are carried at amortized cost of $5,887,500. The fair market value of these investments as of June 30, 2004 were $5,734,710, resulting in unrealized losses of $152,790.

5. Acquisition of Public Safety Group, Inc.

On March 30, 2004, we acquired all of the outstanding capital stock of Public Safety Group, Inc. (PSG), a privately-held leader in wireless solutions for law enforcement and public safety markets based in Winter Park, Florida. The acquisition was completed pursuant to the terms of an Agreement and Plan of Merger (the Merger Agreement) by and among the Company, BIO-Key Acquisition Corp., a wholly-owned subsidiary of the Company, PSG and all of the shareholders of PSG. As a result of this transaction PSG became a wholly-owned subsidiary of the Company and now constitutes a division of our business specializing in the law enforcement and public safety markets (the Public Safety Division). The business combination will be accounted for using the purchase method.

Pursuant to the Merger Agreement, we purchased all of the outstanding capital stock of PSG from the former shareholders of PSG in exchange for an aggregate of 2,416,108 shares of our common stock issued to the former shareholders of PSG, 6,000 shares of our common stock issued to Harward Investments, Inc. (Harward) pursuant to an arrangement involving the discharge of certain outstanding debt obligations of PSG to Harward as of March 30, 2004, $500,000 in cash, and our assumption of $600,000 in aggregate net liabilities of PSG. The Merger Agreement provides that any liability or obligation of PSG in Excess of such $600,000 limitation, whether arising before or after the effective date of the merger, will be solely the responsibility of the former shareholders of PSG. Additional earnout consideration, determined as a proportion of revenues attained by the Public Safety Division over fiscal years 2004 and 2005, may be paid to the former shareholders of PSG. The Company will make payments of such additional consideration on the last day of the month following each month in which the Public Safety Division achieves specified revenue milestones during fiscal years 2004 and 2005. Such payments will be made in cash, unless the aggregate amount of earnout consideration exceeds sixty percent (60%) of the aggregate consideration paid by the Company in the merger transaction. Any such excess amounts will be paid in shares of our common stock priced as of two (2) days prior to the date on which any earnout payment becomes due. In connection with this acquisition, three former employees of PSG, who were also shareholders of PSG, entered into two-year employment agreements with the Company to serve within the Public Safety Division.

The 2,416,108 shares issued to the PSG shareholders (the Merger Shares) are subject to escrow provisions contained in the Merger Agreement and a related escrow agreement, which provide for periodic releases of the shares from escrow on a schedule determined by the revenues achieved by the Public Safety Division during fiscal years 2004 and 2005. The owners of such escrowed shares, however,

F-26

will continue to enjoy all the rights and privileges attributable to the shares, including, without limitation, the right to vote and receive dividends. The principal terms of the escrow arrangement are as follows:

•: One-twelfth (¹/12) of the Merger Shares are held in escrow for the purpose of securing certain prior obligations of PSG to Harward and will be released upon the effectiveness of this registration statement to the shareholders of PSG and Harward.
•: The remaining eleven-twelfths (¹¹/12) of the Merger Shares will be released to the former shareholders of PSG at quarterly intervals, on a distribution schedule determined by the revenues achieved by the Public Safety Division during 2004. According to the distribution schedule, all of the Merger Shares will be released as early as June 30, 2006 but no later than December 31, 2007.
•: Of the remaining eleven-twelfths (¹¹/12) of the Merger Shares, those shares owned by former employees of PSG who became our employees by virtue of the merger transaction are subject to repurchase by us under certain circumstances involving the termination of such employee's employment. Shares remaining in escrow may also be used to fund identification obligations of the former PSG shareholders pursuant to the Merger Agreement.

A summary of the estimated fair value of the net assets acquired and liabilities assumed, pertaining to the purchased entity is as follows:

Current assets		$	133,369
Goodwill			2,535,445
Copyrighted software			1,181,429

Deferred Offering Costs

In March 2002, the Company engaged an investment banking firm to advise the Company regarding raising additional capital through the potential future issuance of the Company's equity, debt or convertible securities. The Company paid a nonrefundable retainer fee of $50,000, out of pocket expenses of $14,900 and granted a four year warrant to purchase 25,000 shares of the Company's common stock at an exercise price of $1.00 per share. The estimated value of the warrant is $17,000. These deferred costs were charged to operations in the quarter ended March 31, 2004, when this engagement terminated.

Impairment of Goodwill

The Company has adopted SFAS No. 142. In accordance with the adoption of this standard, the Company has not amortized goodwill. As required under SFAS No. 142, the Company performed an assessment of the carrying value of goodwill using a number of criteria, including the value of the overall enterprise, and as of June 30, 2004, the Company believes no material impairment exists. Future impairment charges from existing operations or other acquisitions, if any, will be reflected as an operating expense in the statement of operations.

10. Note Payable

Pursuant to the Merger Agreement, the Company assumed a maximum of $600,000 in aggregate net liabilities of PSG, which included a note payable of $400,000. This note was subsequently paid off in April 2004.

11. Long-term Obligations

Between January 4, 2004, and March 29, 2004 as part of the Company's January 2003 amended funding transaction with an investor group (the Investor), the Investor has provided additional financing of $1,000,000 (the Funding Agreement) in incremental monthly installments.

On March 30, 2004 the Company issued 18,275 shares of series C convertible preferred stock to the Investor in exchange for the cancellation of $1,770,500 principal amount of outstanding convertible promissory notes and $49,963 of accrued interest due thereunder.

12. Stockholders Equity

Common Stock

On March 31, 2004, the Company entered into a securities purchase agreement with certain institutional and accredited investors pursuant to which the Company issued and sold an aggregate of 8,888,928 shares of common stock and warrants to purchase an aggregate of 4,444,464 shares of common stock. The investors paid an aggregate purchase price of $1.35 for each share of common stock and warrant to purchase 0.5 of a share of common stock, resulting in gross proceeds of approximately $12,000,000. In connection with the securities purchase agreement, the Investor paid for a portion of their purchased stock and warrants by canceling $347,500 of outstanding debt. The remaining aggregate proceeds of $11,248,803, net of offering costs totaling $403,700, were held in escrow until April 2004. During March 2004, additional out of pocket offering costs of $14,397 were accrued by the Company.

The Warrants may be exercised at any time prior to the Fifth anniversary of the effective date of this registration statement at an exercise price of $1.755 per share. Each Warrant contains anti-dilution protection, which provides that if at any time on or prior to March 31, 2005, we issue any of our common stock or rights, options, warrants or other securities or debt bearing a right to acquire our common stock at a price less than the then-applicable exercise price of such Warrant, such exercise price will be automatically reduced to such lower price. Fifty percent (50%) of any unexercised portions of the Warrants are callable by the Company if the volume weighted average trading price per share of our common stock exceeds $4.3875 per share for ten (10) consecutive trading days and the Warrants have not been exercised after forty-five (45) days' prior notice from the Company.

not listed or quoted, or is suspended from trading, on an eligible trading market for a period of three (3) trading days (whether or not consecutive), the Company will be required to pay a cash amount to the investors equal to one percent (1%) of the aggregate purchase price paid by the investors pursuant to the Purchase Agreement for the first month that such event occurs and one percent (1%) for each month thereafter in which such event remains uncured, in each case prorated for any partial month. If the Company fails to make any such payment in a timely manner, such payment shall bear interest at the rate of one percent (1%) per month (prorated for partial months) until paid in full.

Proforma Compensation Disclosure

In December 2002, the Financial Accounting Standards Board (FASB) issued SFASB No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure. SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary charge to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 requires expanded and more prominent disclosure in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported results.

The Company has not adopted a method under SFAS No. 148 to expense stock options but rather continues to apply the recognition and measurement provisions of APB Opinion No.25, Accounting for Stock issued to Employees, and related interpretations in accounting for those plans. No stock-based employee compensation expense for options is reflected in net income for the fiscal periods presented as all options granted under those plans had an exercise price equal to or lower than the market price of the underlying common stock at the date of grant.

13. Legal Proceedings

In June 2003, PSG, our recently-acquired subsidiary, was named as a defendant in a civil action initiated in the Superior Court Department in Hampden County, Commonwealth of Massachusetts by The Vince Group, Inc. ("TVG"). The case has since been removed to the United States District Court for the District of Massachusetts at the request of the Parties. The complaint claims that PSG is obligated to pay a percentage of certain of its revenues to TVG in consideration for a strategic business introduction allegedly made by an agent of TVG. PSG has denied the allegations and filed an answer in the litigation, and as of the date of this report the outcome of the litigation is pending. The claim is for an unspecified amount including actual damages, interest, and attorney's fees. Management believes that the claim is without merit and will be settled out of court for an amount that will not have a material adverse affect on our business, financial condition or operating results.

NOTES TO FINANCIAL STATEMENTS

December 31, 2003 and 2002

NOTE A—THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Public Safety Group, Inc. (the Company) incorporated on March 1, 2000, with operations in Winter Park, Florida. The Company provides wireless solutions for the public safety industry, government agencies and the private sector. The Company's wireless solutions allow law enforcement officers to access State and Federal databases over a wireless network.

Summary of Significant Accounting Policies

A summary of the significant accounting policies consistently applied in the preparation of the accompanying financial statements follows:

1. Revenue Recognition

Revenues from software licensing are recognized in accordance with Statement of Position (SOP) 97-2, Software Revenue Recognition, as amended by SOP No. 98-9. Accordingly, revenue from software licensing is recognized when all of the following criteria are met: persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable, and collectibility is probable.

The Company enters into arrangements with end users for items, which may include software license fees, maintenance fees and services or various combinations thereof. For each arrangement, revenues will be recognized when evidence of an agreement has been documented, the fees are fixed or determinable, collection of fees is probable, delivery of product has occurred and no other significant obligations remain.

Multiple-Element Arrangements: For multiple-element arrangements, each element of the arrangement will be analyzed and the Company will allocate a portion of the total fee under the arrangement to the elements using vendor specific objective evidence within the contract of each element. Vendor specific objective evidence is based on the price the customer is required to pay when the element is sold separately (i.e., software license fees charged when consulting or other services are not provided, hourly rates charged for consulting services when sold separately from a software license or usage fees). If vendor specific objective evidence of fair value does not exist for any undeliverable elements, all revenue will be deferred and recognized ratably over the service period if the undeliverable element is services, or until sufficient objective evidence of fair value exists or all elements have been delivered.

License Revenues: Amounts allocated to license revenues are recognized at the time of delivery of the software and all other revenue recognition criteria discussed above have been met.

Maintenance Revenues: Amounts allocated to maintenance revenues are recognized ratably over the contract period. Maintenance contract periods range from nine months to twenty four months. Maintenance contracts provide customers technical assistance and support and new or revised versions of software.

Service Revenues: Revenues from services are comprised of consulting and implementation services. Services are generally separable from other elements under the arrangement since performance of the services is not essential to the functionality of any other element of the transaction. Revenues from services are generally recognized as the services are performed.

F-41

2. Cash and Cash Equivalents

Cash equivalents consist of certificates of deposit and all other liquid investments with original maturities of three months or less. The Company maintains its cash balances in a financial institution in Florida. These balances are insured by the Federal Deposit Insurance Corporation up to $100,000.

3. Accounts Receivable

4. Equipment, Furniture and Fixtures

Equipment, furniture and fixtures are stated at cost. Depreciation is provided for in amounts sufficient to relate the cost of depreciable assets to operations over their estimated services lives of three to seven years using the straight-line method. Equipment, furniture and fixtures consisted of the following as of December 31:

	2003			2002
Computer equipment	$	4,225		$	1,276
Computer software		3,222			1,187
Furniture		218			—

		7,665			2,463
Less: accumulated depreciation		(2,110	)		(978	)

	$	5,555		$	1,485

5. Advertising Expense

The company expenses the costs of advertising as incurred. Advertising expenses for the years ended December 31, 2003, and 2002, were approximately $3,750 and $1,350, respectively.

6. Research and Development Expenditures

F-42

7. Income Taxes

The Company elected in March 2000, to be taxed under the provisions of Subchapter S of the Internal Revenue Code. Under those provisions, the Company does not pay federal corporate income taxes on its taxable income. Instead, the stockholders are liable for individual federal income taxes on their respective shares of the Company's taxable income.

8. Accounting for Stock-Based Compensation

In December 2002, the Financial Accounting Standards Board (FASB) issued SFAS No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure. SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 requires expanded and more prominent disclosure in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported results.

The Company has not adopted a method under SFAS No. 148 to expense stock options but rather continues to apply the recognition and measurement provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for those plans. No stock-based employee compensation expense for options is reflected in net income for the fiscal years presented as all options granted under those plans had an exercise price equal to the market value of the underlying common stock at the date of grant. A pro forma effect table is presented in the Pro Forma Compensation Disclosure section of Note G, which assumes the fair value recognition provisions of SFAS No. 123 would have been adopted for all options granted.

9. Use of Estimates

NOTE B—ADVANCES TO STOCKHOLDERS

Advances to stockholders are non-interest bearing receivables and are due on demand.

F-43

NOTE C—ACCRUED LIABILITIES

Accrued liabilities consisted of the following as of December 31:

	2003		2002
Interest	$	89,364	$	93,931
Other		11,761		1,381

	$	101,125	$	95,312

NOTE D—NOTES PAYABLE

Notes payable consisted of the following as of December 31:

	2003		2002
Note payable	$	503,836	$	604,778
Due to reseller		—		40,000

	$	503,836	$	644,778

The Company has a note payable with an investment firm. The loan had an original maturity date of June 1, 2003 and was extended by the Company until June 1, 2004, at which time the outstanding principal and all accrued interest is due and payable. Throughout the term of this agreement, the Company is required to make monthly principal payments equal to thirty percent of the Company's actual receipts from license fees during the preceding calendar month. The Company shall also pay all accrued interest on a monthly basis. The note is collateralized by certain personal and intangible property of the Company. Prior to the extension on June 1, 2003, interest accrued at the greater of 4% in excess of the rate established by Bank of America as its "prime rate" from time to time or 10% per annum. Subsequent to June 1, 2003, interest accrues at the rate of 2% in excess of the rate established by Bank of America as its "prime rate" from time to time.

In December 2002, the Company borrowed $40,000, from a reseller agent. The entire amount was repaid in March 2003, along with interest of $500, in full satisfaction of this obligation.

NOTE E—COMMITMENTS AND CONTINGENCIES

In June 2003, the Company was named as a defendant in a civil action initiated in the Superior Court Department in Hampden County, Commonwealth of Massachusetts by The Vince Group, Inc. (TVG). The case has since been removed to the United States District Court for the District of Massachusetts at the request of the Parties. The complaint claims that the Company is obligated to pay a percentage of certain of its revenues to TVG in consideration for a strategic business introduction allegedly made by an agent of TVG. The Company has denied the allegations and filed an answer in the litigation, and as of the date of this report the outcome of the litigation is pending. The claim is for an unspecified amount including actual damages, interest, and attorney's fees. Management believes that the claim is without merit and will be settled out of court for an amount that will not have a material adverse affect on the business, financial condition or operating results of the Company. The Merger Agreement (see Note J) provides that any liability or obligation generated by this litigation will be solely the responsibility of the former shareholders of PSG.

F-44

NOTE F—STOCKHOLDERS' DEFICIT

On September 29, 2003, the Company entered into a settlement agreement with a former employee under which the employee returned 120 shares of common stock outstanding in exchange for the Company's forgiveness of an outstanding employee advance of $7,839.

In January 2002, the Company sold 749,000 shares of common stock for $7,490 ($0.01 per share) to certain officers, employees and consultants of the Company. On February 20, 2002, the Company sold 31,250 shares of common stock to an unrelated party for $50,000 ($1.60 per share).

NOTE G—STOCK-BASED COMPENSATION

Under agreements entered into on June 20, 2003, the Company has granted options to purchase an aggregate of 600,000 shares of common stock to various key employees. These options have an exercise price of $1.60 per share, vested immediately upon grant and have a remaining life of approximately 4.5 years as of December 31, 2003. These options were canceled in connection with the subsequent acquisition of the Company as discussed in Note J.

Summary Option Information

The fair value of options granted to employees during 2003 was $1.14 per share. The fair value of each option is estimated as of the date granted using the Black-Scholes option-pricing model utilizing the same assumptions presented in the pro forma compensation disclosure section below.

Pro Forma Compensation Disclosure

In December 2002, the Financial Accounting Standards Board (FASB) issued SFASB No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure, SFAS No. 148 amends SFAS No. 123, Accounting for Stock-Based Compensation, to provide alternative methods of transition for a voluntary charge to the fair value based method of accounting for stock-based employee compensation. In addition SFAS No. 148 requires expanded and more prominent disclosure in both annual and interim financial statements about the method of accounting for stock-based employee compensation and the effect of the method on reported results.

The Company has not adopted a method under SFAS No. 148 to expense stock options but rather continues to apply the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for those plans. No stock-based employee compensation expense for options is reflected in net earnings for the fiscal periods presented as all options granted under those plans had an exercise price equal to or higher than the market price of the underlying common stock at the date of grant.

If compensation expense for the stock options granted in 2003 had been determined based on the fair value at the grant date consistent with the method of SFAS No. 123, the Company's pro forma net loss and pro forma loss per share for the year ended December 31, 2003, would have been as follows:

Net earnings (loss)
	As reported	$	223,256
	Pro forma		(460,744	)

F-45

In determining the pro forma compensation cost of the options granted, the fair value of each grant was estimated on the date of grant using the Black-Scholes option-pricing model. The assumptions used to determine the fair value of each grant included the following:

Risk free interest rate	1.90	%
Expected life of options (in years)	3
Expected dividends	—
Volatility of stock price	120	%

NOTE H—FAIR VALUES OF FINANCIAL INSTRUMENTS

The Statement of Financial Accounting Standards Board No. 107 "Disclosures about Fair Value of Financial Instruments" (SFAS 107) requires disclosure of the estimated fair value of an entity's financial instruments. Such disclosures, which pertain to the Company's financial instruments, do not purport to represent the aggregate net fair value of the Company. At December 31, 2003 and 2002, the carrying value of all material financial instruments, for which it is practicable to estimate the fair value, approximated fair value because of the short maturity of those instruments and rates available for similar instruments.

BIO-key International, Inc.

INTRODUCTION TO UNAUDITED PRO FORMA FINANCIAL INFORMATION

We are providing the following unaudited pro forma condensed consolidated financial information of BIO-key International, Inc. (BIO-key) and its acquisition of Public Safety Group, Inc. (PSG) to present the results of operations and financial position of BIO-key had the merger been completed at an earlier date.

On March 30, 2004, (the Closing Date) BIO-key entered into and completed an Agreement and Plan of Merger (the Merger Agreement) to acquire all of the issued and outstanding common stock of PSG. PSG has operations in Winter Park, Florida and provides wireless solutions for the public safety industry, government agencies and the private sector. PSG's wireless solutions allow law enforcement officers to access State and Federal databases over a wireless network.

Pursuant to the Merger Agreement, the Company purchased all of the outstanding capital stock of PSG from the former shareholders of PSG in exchange for 2,416,108 shares, at $1.49 per share of our common stock issued to the former shareholders of PSG, 6,000 shares of our common stock issued to Harward Investments, Inc. (Harward) pursuant to an arrangement involving the discharge of certain outstanding debt obligations of PSG to Harward, $500,000 in cash, and the assumption of $600,000 in aggregate net liabilities of PSG. The Merger Agreement provides that any liability or obligation of PSG in excess of such $600,000 limitation will be solely the responsibility of the former shareholders of PSG. Additional earnout consideration, determined as a proportion of qualified revenues, as defined, attained by the Public Safety Division over fiscal years 2004 and 2005, may be paid to the former shareholders of PSG. During 2004, earnout consideration shall be earned at the following rates: Five percent (5%) of all 2004 Qualifying Revenue less than $2 million, less the Accounts Receivable Holdback; as defined; Ten percent (10%) of all 2004 Qualifying Revenue equal to or greater than $2 million but less than $4 million; Twenty percent (20%) of all 2004 Qualifying Revenue equal to or greater than $4 million but less than $7 million; and Thirty percent (30%) of all 2004 Qualifying Revenue equal to or greater than $7 million. During 2005, earnout consideration shall be earned at the following rates: Ten percent (10%) of all 2005 Qualifying Revenue equal to or greater than $7 million but less than $10 million; and Twenty percent (20%) of all 2005 Qualifying Revenue equal to or greater than $10 million. The Company will make payments of such additional consideration on the last day of the month following each month in which the Public Safety Division achieves specified revenue milestones during fiscal years 2004 and 2005. Such payments will be made in cash, unless the aggregate amount of earnout consideration exceeds sixty percent (60%) of the aggregate consideration paid by the Company in the merger transaction. Any such excess amounts will be paid in shares of common stock of the Company priced as of two (2) days prior to the date on which any earnout payment becomes due. In connection with this acquisition, three former employees of PSG, who were also shareholders of PSG, entered into two-year employment agreements with the Company to serve within the Public Safety Division.

The 2,416,108 shares issued to the former PSG shareholders (the Merger Shares) are subject to escrow provisions contained in the Merger Agreement and a related escrow agreement, which provide for periodic releases of the shares from escrow on a schedule determined primarily by the revenue achieved by the Public Safety Division during fiscal year 2004. The owners of such escrowed shares, however, will continue to enjoy all the rights and privileges attributable to the shares, including, without limitation, the right to vote and receive dividends. The principal terms of such escrow arrangement are as follows:

•: One-twelfth (¹/12) of the Merger Shares (the Initial Shares) are being held in escrow for the purpose of securing certain prior obligations of PSG to Harward and will be released upon the effectiveness of this registration statement to Harward and the former shareholders of PSG. Specifically, Harward will receive an amount of Initial Shares that is equal to $110,000 divided

F-47

by the closing price of our common stock as reported by the OT Bulletin Board on such date. The balance of the Initial Shares will be concurrently released to the former shareholders of PSG.

•: An additional one-twelfth (¹/12) of the Merger Shares will be released from the escrow to the former shareholders of PSG on each of June 30, 2004, September 30, 2004 and December 31, 2004.
•: The remaining eight-twelfths (⁸/12) of the Merger Shares (the Remaining Shares) will be released from the escrow to the former shareholders of PSG based on a distribution schedule determined by the license, service and maintenance fee revenue achieved by the Public Safety Division during fiscal year 2004. Specifically, the Remaining Shares will be released according to the following schedule: (i) in the event that such qualifying revenue is less than $2 million, one-twelfth (¹/12) of the Remaining Shares will be released on each of March 31, 2005, June 30, 2005, September 30, 2005, December 31, 2005, March 31, 2006, June 30, 2006, September 30, 2006, December 31, 2006, March 31, 2007, June 30, 2007, September 30, 2007 and December 31, 2007; (ii) in the event that such qualifying revenue is equal to or greater than $2 million, one-eighth (¹/8) of the Remaining Shares will be released on each of March 31, 2005, June 30, 2005, September 30, 2005, December 31, 2005, March 31, 2006, June 30, 2006, September 30, 2006 and December 31, 2006 and (iii) in the event that such qualifying revenue is equal to or greater than $6 million, one-sixth (¹/6) of the Remaining Shares will be released on each of March 31, 2005, June 30, 2005, September 30, 2005, December 31, 2005, March 31, 2006 and June 30, 2006.
•: Of the shares remaining in escrow following the effectiveness of this registration statement, those shares owned by former employees of PSG who became employees of the Company by virtue of the merger transaction are subject to repurchase by the Company under certain circumstances involving the termination of such employee's employment. Shares remaining in escrow may also be used to fund indemnification obligations of the former PSG shareholders pursuant to the Merger Agreement.

The unaudited pro forma condensed consolidated balance sheet of the Company gives effect to the merger as if it had occurred on December 31, 2003 and the unaudited pro forma condensed consolidated statement of operations of the Company gives effect to the merger as if it had occurred on January 1, 2003 for the twelve months ended December 31, 2003.

The acquisition of PSG is accounted for under the purchase method of accounting in accordance with the Statement of Financial Accounting Standards No. 141, Business Combinations ("SFAS 141"). Under the purchase method of accounting, assets acquired and liabilities assumed are recorded at their estimated fair values. Goodwill and other finite intangible assets are created to the extent that the merger consideration, including certain acquisition and closing costs, exceeds the fair value of the net identifiable assets acquired at the date of the merger. Based on the preliminary information currently available, we expect to recognize goodwill and other finite intangible assets of approximately $4,600,000. Upon completion of a formal purchase price allocation there may be a decrease in the amount assigned to goodwill and a corresponding increase in tangible or other intangible assets.

This unaudited pro forma condensed consolidated financial information is based on the estimates and assumptions set forth herein and in the notes thereto. The unaudited pro forma results for the twelve months ended December 31, 2003 have been prepared utilizing (a) the audited financial statements of BIO-key included in Form 10-KSB for the fiscal year ended December 31, 2003; and (b) the audited financial statements of PSG for the twelve months ended December 31, 2003.

F-48

The following unaudited pro forma financial information is presented for informational purposes only and is not necessarily indicative of (i) the results of operations of the Company that actually would have occurred had the Merger Agreement been consummated on the dates indicated or (ii) the results of operations of the Company that may occur or be attained in the future. The following information is qualified in its entirety by reference to and should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," BIO-key's audited consolidated financial statements, including the notes thereto contained in its Annual Report on Form 10-KSB for the year ended December 31, 2003, PSG's audited financial statements, including the notes thereto, for the years ended December 31, 2003 and 2002, and other historical financial information appearing elsewhere herein.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 24. Indemnification of Directors and Officers.

Section 302A.521 of the Minnesota Business Corporation Act ("MBCA") generally provides for the indemnification of directors, officers or employees of a corporation made or threatened to be made a party to a proceeding by reason of the former or present official capacity of the person against judgments, penalties and fines (including attorneys' fees and disbursements) if such person, among other things, has not been indemnified by another organization, acted in good faith, received no improper personal benefit and with respect to any criminal proceeding, had no reasonable cause to believe his conduct was unlawful.

As permitted under the MBCA, the Articles of Incorporation of the Company provide that directors shall have no personal liability to the Company or to its shareholders for monetary damages arising from breach of the director's duty of care in the affairs of the Company. The MBCA does not permit elimination of liability for breach of a director's duty of loyalty to the Company or with respect to certain enumerated matters, including payment of illegal dividends, acts not in good faith and acts resulting in an improper personal benefit to the director. The By-Laws of the Company provide that the Company shall indemnify any person, who was or is a party to a proceeding by reason of the fact that he is or was a director, officer, employee or agent of the Company against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with such proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the Company, in accordance with and to the full extent permitted by, the MBCA.

In addition, the registrant has purchased directors and officers liability insurance.

Item 28. Undertakings.

(a)

The registrant hereby undertakes:

(1): to file, during any period in which offers or sales are being made, a post-effective amendment of this registration statement (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

II-5

(2): for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and
(3): to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
