How works iris scanner. 

To scan iris, a normal camera and an infrared camera are attached in the device. Both of these cameras take a picture of your eyes together, which is a very high resolution picture. After that, your device collects imported data from the picture. for example where is diversion, where is conversion, where is curve and where is arc in the picture. It recognizes all things And prepares a code about them. We call it Iris Code. And stores them in their database.



When the same person goes to verify again, then the picture of the eye is taken by the infrared camera and the normal camera. And by converting it into code, it is matched with the code already saved. The user is given access to the code when match.

There are 40 to 50 points in fingerprint scanning that identify the scan. But there are 240 to 250 points in iris scanning, which only validates when the match is over.
