Sentry Enterprises is a technology company based in West Chester, Pennsylvania, focused on digital identity, biometric hardware and software, and converged fintech solutions. The company develops products and infrastructure that span physical and digital identity verification, access control, payment, and cryptocurrency storage. Sentry's product portfolio includes biometric smart cards and credentials, such as a batteryless multi-function biometric credential, a biometric cold storage cryptocurrency wallet (certified by a security lab), and the Radiance platform — an OLED-based transaction card illumination system developed using encapsulation technology. Their SentryCard product line supports both logical and physical access control use cases. In 2023, Sentry completed a merger with X-Core Technologies, which brought in patented Prelaminate Core Sheet technology enabling ultra-thin microelectronic manufacturing via hot lamination. This expanded Sentry's in-house card manufacturing capabilities. The company operates under a self-sovereign identity (SSI) framework and targets markets including identity management, payment processing, access control, healthcare, and cryptocurrency. Sentry has established partnerships with companies such as Infineon, IDEMIA, Fingerprint Cards, IDEX Biometrics, Fidesmo, and Konica Minolta, among others. Notable collaborations include a biometric access control and cold storage crypto wallet platform with Infineon, and a partnership with Allegion for biometric protection of virtual security keys. The company also announced a partnership with Global Accountability Corp focused on identity access management.
