Eye scan

There two types of uses of biometrics for recognising the eyes for authentication – the retina and the iris. While seemingly of a similar nature, there are, naturally, some notable differences. Retina scanning, while highly accurate, is extremely expensive hardware to buy, install and maintain and, of the two methods, it is rather intrusive. Iris scanning on the other hand is nearly equally as accurate in identifying people but is not as intrusive, requiring a camera that can be up to 12” away, making it less uncomfortable for the person involved. What’s more, iris scanning uses lower amounts of storage space, ultimately saving you money on maintenance costs compared to retina
