More Info

The ATKey.Card NFC packages AuthenTrend’s biometric FIDO2 stack into a credit card form factor. It carries a fingerprint sensor, NFC for tap to authenticate, and MIFARE Type A for badge access dual use. AuthenTrend also sells the ATKey.Badge, a USB-C reader released in 2025 that adds a wired connection for the card.

The card form factor competes with GoTrust IdemCard but with biometrics added. Fingerprint enrolment is performed over the badge accessory or through host platform WebAuthn flows.
