are we sure it isn't just taking a picture of our fingerprint and logging it in to some giant database? If I touched the screen with a band-aided finger, would they allow that? Not that I am paranoid, and not that they don't already know where I am, what i am thinking and what I am planning to do, and to whom, I like to think I have managed to evade being fingerprinted...I'd rather keep some portion of my self un"databased"

just call me Chicken Little.....
