Iris Scan - These take a picture of your iris (the colored portion of your eye), just like an optical fingerprint reader. Very simple for the user, and non invasive. Some Iris Scanners can read irises from several feet away as a person is walking, so they don't have to stop at a terminal to be scanned. Not to be confused with Retinal Scan, and vendors will point that out about 3 times every 5 minutes.


I've got a question about the practicalities of the 'walking retina' scanner. In order for this to work well, wouldn't you would need an insanely high resolution camera or one with great magnification and an equally high quality tracking/positioning system to take a (let's say) 100x100 px image of an eye? Plus all the crazy fast calculations the computer would have to make in ~3s...this system has to be ridiculously expensive. I would really appreciate any more details about this if you have the time - it seems fascinating
