Biometric Smart Card Technology

Biometric smart cards that drop into the line you already have

On-card fingerprint enrollment and matching — batteryless, hot-lamination-compatible, available as a mill-and-attach drop-in or fully embedded. License the IP or co-develop on Sentry’s ThinTech™ platform.

Where the platform fits

Wherever a credential needs on-card biometric proof of identity — payment, access, MFA, or government ID — Sentry’s encapsulated biometric SiP drops into existing card-manufacturing lines, batteryless and hot-lamination-compatible.

Markets we serve

Biometric payment cards

On-card fingerprint authorization for contactless and contact payments — no PIN, no battery, reader-harvested power.

Government ID & credentials

Tamper-evident credentials aligned with CAC/PIV as a FIDO2 derived-credential solution.

Enterprise access & MFA

One credential for physical access and passwordless multi-factor authentication across every system.

Metal smart cards

Biometrics and secure elements in a metal core — without the RF detuning that plagues conventional metal cards.

Drop-in, by design

Conventional biometric cards fail at the end of a five-step build — pop-out, attach failure, registration loss. Sentry’s encapsulated biometric SiP replaces that with four steps: encapsulated SiP, prelam, standard hot-lam, finished product. The electrical joint carries current, not mechanical load; encapsulation seals the structure. Adopt it as a mill-and-attach drop-in or a fully embedded build. Card manufacturers license the prelaminate core and run it on existing hot-lamination lines — no new equipment, no line changes.

Proven, certified, shipping

Sub-400 ms biometric match, FIDO2-certified (Authenticator, Certification Level 1, v2.0), Infineon SLC39 secure element, ISO 10373 bend and torsion, hot-lamination compatible at 130–150°C, and offline operation — full match-time, certification, and durability data reviewable under NDA.

Built for enterprise and government. Secure, tamper-evident smart cards align with CAC/PIV as a FIDO2 derived-credential solution — one credential for biometric access, MFA, and payment.
