BIO-key provides identity and access management (IAM) software. Its core platform, PortalGuard, offers multi-factor authentication and single sign-on capabilities to secure access to applications and networks. The company distinguishes itself with Identity-Bound Biometrics (IBB), a technology that ties authentication to the individual rather than a hardware device or smartphone. This approach serves industries where mobile devices are restricted or shared, including manufacturing, healthcare, and high-security government and defense settings. BIO-key also manufactures and sells fingerprint scanners designed to work with its software platform. The company operates primarily through a subscription-based business model, selling multi-year software licenses with revenue determined by the number of users or endpoints. Software licenses represent the most profitable portion of the business, supplemented by recurring support services and hardware sales. BIO-key uses a direct sales force in the U.S. and a global network of channel partners for international distribution. Strategy focuses on expanding into international markets, particularly within the defense and financial services sectors, while leveraging partnerships to increase penetration in the U.S. public sector.
