What is a retina scan?

Retina scanning and iris scanning are two different types of biometric authentication technologies used to verify individual identities based on unique eye patterns. Retinal scanners use an infrared light to detect detailed patterns of retinal blood vessels, while iris scanners focus on the unique pattern of the iris. Both are typically used in high-security contexts, but are not foolproof. Retinal imaging, a distinct process, is leveraged by ophthalmologists to examine conditions of the eye. The emergence of biometric authentication technology also raises concerns about security and privacy.
