There are supposedly some new techniques that look at the infrared signature of your face (like, I guess, distribution & position of hot & cold spots), and that's less likely to be fooled by facial hair and other superficial disguises. It's probably a fairly simple technology, and could be applied to the credit card ID problem.

I think this is based on looking at your face with near-infrared, not the medium and far (thermal) infrared. Near infrared is supposed to penetrate flesh far better, so your blood vessels are visible and form a pattern which can be recognized. Jim Bell jimbell@pacifier.com
