Layer 03 · Biometric authentication

Match-on-card fingerprint authentication with no biometric database

The fingerprint is enrolled, encrypted and matched entirely inside the badge, so biometric data never touches a network or a server and there is no central repository to breach.

Quick answer

S-Badge uses match-on-card biometric authentication. The cardholder's fingerprint is enrolled on the badge, converted into an encrypted mathematical template, and matched inside the secure element. The template never leaves the card, so the organization holds no biometric database. Scan latency is under 380 ms.

What the biometric layer does

  • Enrollment in under 30 seconds

    The cardholder scans a fingerprint on the badge (three touches per finger, up to two fingers). Standalone enrollment needs no IT administrator and exposes no network credentials.

  • Matching inside the secure element

    Fingerprint templates are enrolled, encrypted and matched entirely inside the secure element. Biometric payloads never transmit over wireless networks or reach remote servers.

  • No central biometric database

    Because the enterprise never collects, stores or transmits biometric files, there is no honeypot database for attackers to target.

  • Liveness check

    A capacitive dermal impedance pulse check resists spoofing methods such as latex casts that defeat optical-only systems.

  • Instant match

    Scan latency is under 380 ms, and a tap unlocks physical doors and logical sessions in less than one second.

  • Patented technology

    GNS lists U.S. patent numbers 15/937,683 and 62/360,444 for S-Badge technology.

Answers

Common questions

Where is my fingerprint stored?

Only inside the secure element of your own badge. It is not sent to, or stored on, any server.

What if the badge is lost or stolen?

The badge stays disabled unless the cardholder's fingerprint matches on the card, so a lost badge cannot be used by someone else.

How is the sensor protected against fake fingerprints?

S-Badge uses a capacitive dermal impedance pulse check for liveness, rather than optical capture alone.
