retinal scans
Biometric eye readings
Retinal scans are biometric identification procedures that map the unique pattern of blood vessels at the back of the eye.
Because each person's retinal pattern is distinct and stable, the technology serves high-security applications—though it's less common than iris scanning or fingerprints.
In fiction, retinal scans often appear as futuristic security measures: The vault required a retinal scan to open.
