biometric scan
Body-based authentication method
A biometric scan is a digital reading of a physical characteristic used to verify identity—fingerprints, iris patterns, facial features, or voice.
The technology appears in security systems, phone unlocks, and border checkpoints: The airport uses biometric scans instead of boarding passes.
The scan converts biological data into a unique identifier that's difficult to forge or share.
