NFC

NFC enables intentional, proximate interaction between a Keyra card and readers or phones—supporting tap-to-verify and tap-to-authorize patterns.

Detail

How it fits Keyra

Intentional proximityPhysical presence remains a powerful signal when paired with cryptographic verification.

A secure element provides a hardware root of trust for storing keys and performing cryptographic operations outside ordinary application memory.

Human authorization answers whether a real person approved a specific action—critical when AI agents can act, negotiate, or initiate transactions.

Biometrics help establish that a present human—not only a possessed device—is participating in an authorization.

Keyra’s technology topics connect secure hardware, cryptographic identity, and human authorization into one trust architecture.
