PocketKey NFC Card (dual

The ACS PocketKey NFC Card (AFD02) is a card-format security key for passwordless or multi-factor online sign-in. It supports FIDO U2F and FIDO2 CTAP2.1, providing a physical authentication option for compatible services.

The card communicates through ISO 14443 Type A contactless technology and uses the full-size ISO/IEC 7810 ID1 card format. ACS says FIDO cryptographic keys are stored on the card, with unique keys created for each website.

The manufacturer lists support for Windows, Linux, macOS, iOS and Android, plus Chrome, Safari, Microsoft Edge and Firefox. This makes the card suitable for personal accounts and organizational sign-in where the platform and service support FIDO authentication.
