what is dynamic iris recongnition

Question

anonymous · Answer

Your iris has a unique pattern, and is already used to identify you (so long as you are standing still in front of a camera) by border control agencies in the UK, Netherlands, United Arab Emirates, US and Canada. In the film, people's irises are read while they're on the move, presenting the extra challenge of movement and resolution. But with cameras and computers improving all the time, don't bet against this not being ready way before 2054.
