What Is Iris Recognition?
Benefits of Using Iris Technology
- The iris is a thin membrane on the interior of the eyeball. Iris patterns are extremely complex.
- Patterns are individual (even in fraternal or identical twins).
- Patterns are formed by six months after birth, stable after a year. They remain the same for life.
- Imitation is almost impossible.
- Patterns are easy to capture and encode
