How does a retina scanner work?

What will be an ideal response?


A retinal scanner uses the human retina as a biometric identifier. The retina is a layer at the back (posterior) portion of the eyeball that contains cells sensitive to light, which trigger nerve impulses that pass these through the optic nerve to the brain, where a visual image is formed. Due to the complex structure of the capillaries that supply the retina with blood, each person's retina is unique.
