biometric systems
Identity verification technology
Biometric systems use unique physical or behavioral characteristics to identify or verify individuals.
Fingerprints, facial features, iris patterns, voice, and gait can all serve as biometric identifiers.
These systems appear in security contexts—unlocking phones, passing through airport checkpoints, accessing restricted areas: The building uses a biometric system for entry.
Unlike passwords, biometric data cannot be forgotten or easily shared.
