Biometrics refers to methods of recognizing a person based on their unique physical or behavioral characteristics. Iris recognition, fingerprint scanning, and handwriting analysis (signature dynamics or forensic analysis) are all forms of biometrics. A card reader and card system, however, is a token-based access control system. The card is a physical object (token) that the person possesses, and the reader verifies the information stored on the card. The identification is based on possession of the token, not on a unique characteristic of the person themselves.
Biometric identification uses inherent personal characteristics (like iris, fingerprint, voice, face), whereas token-based systems rely on possessing an object (like a card or key).
