Question

how does retina scan works for identity...

Answer 1

HELLO FRIEND

_______________

A retinal scanner uses infrared light for mapping. As a person looks into the eyepiece, an invisible beam of low-energy infrared light traces a circular path on the retina at the back of the eye. The blood-filled capillaries absorb more of the infrared light than the surrounding tissue.
