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).

Biometric systems offer a higher level of security than simple token-based systems as biometric characteristics are difficult to forge or transfer. However, they also raise privacy concerns. Access control systems can be purely token-based, purely biometric, or use a combination of methods (e.g., card + PIN, card + fingerprint).
