The hilarious moment a Kentucky man was tricked into thinking a doorbell camera was actually a retinal scanner has been caught on camera. The elderly man was reportedly told by his son-in-law that his doorbell camera could identify a caller from a retinal screening. Footage obtained by Newsflare shows the confused looking man approach the door of a home in Lainesville on July 1.
He then proceeds to peer into the camera for several moments, ensuring he gets up close to it so the ‘technology’ can screen his retina. The man later walks away from the house and looks bewildered as nothing happens. Retinal scanners are typically used for authentication and identification purposes.
Retinal scanning has been used by several government agencies and is now used for ATM identity verification and fraud prevention. The retina is a thin tissue composed of neural cells that is located in the posterior portion of the eye.
Each person’s retina is unique because of the complex structure of capillaries that supply the retina with blood. The technology is relatively simple, with the person looking into a small box-like object where infrared light in a low beam scans the retina.
