ACS’s PocketKey NFC Card provides users the experience of secure and swift passwordless online login. It allows individuals, enterprises and government-scaled agencies to substitute passwords with multi-factor authentication or two-factor authentication, reducing reliance on static passwords.

The PocketKey NFC Card is certified by the FIDO Alliance [FIDO®] and is compliant with FIDO U2F and FIDO2 protocols.  The card’s cryptographic security module terminates any likelihood of phishing, password/identity theft and repetitive attacks.  User tracking can also be prevented by storing FIDO cryptographic keys on-device and creating unique keys for each website.

The PocketKey NFC Card is also compatible with operating systems such as Windows®, Linux®, macOS and Android™, and as well as major web browsers: Chrome™, Safari®, Microsoft Edge® and Firefox®.
