retinal scanner

Biometric eye device

A retinal scanner is a biometric security device that identifies individuals by analyzing the unique pattern of blood vessels at the back of the eye.

The technology shines low-intensity light into the eye to capture the retinal pattern, which is as distinctive as a fingerprint.

Retinal scanners appear frequently in spy films and high-security facilities: The vault required a retinal scan for entry.
