Biometric technologies are ineffably cool. For those not geeky enough to know, biometrics are measurements that allow you to recognize a person using distinguishing traits. For instance, if you were to wake up one morning with your eye (or eyes) so horribly swollen and crazy-looking* that you were unrecognizable, your fingerprint (a common biometric) would enable you to be recognized, despite the bad case of monster-eye. Using biometrics as identifiers is getting more and more common; students are paying for their meals with their thumbs, airports are looking into iris scanning — soon, you won't need a password for anything. Today, we're going to update you on the latest in biometric technologies... how do you feel about the new identifiers? Too Minority Report?
