Biometrics on the move

I've often wondered why the seating in airports is so uncomfortable. Is it to prepare you for the inevitable discomfort of the journey ahead or is it just a total failure of imagination? Anyway here we are again in our serried ranks, this time in San Francisco, uncomfortable as usual when there's an announcement. US immigration are staging a 'biometric exit operation' just before boarding. Just when you thought you'd escaped notice and could slink off they're tracking your departure. In the end it's not as bad as it sounds. You just step up - when you're told, of course - and stand on two large yellow footprints glued to the floor while they take your picture. That's it, and off you go. They could have just announced that instead, 'We'll take your picture as you leave'. Biometric exit operation sounds better, but then again it's slightly more honest. Yes, they take your picture, it's simple....and then. It's the and then bit which is hidden. Hidden, like so much in our machine age. You have to imagine how your image becomes data, matched by face recognition software, tallied against finger and thumbprint records and passport details that connect your age, sex and nationality with where you've been and what you said you were doing, and it's all done behind the scenes. Then and there you just get a polite but slightly officious person in uniform who presses a button before telling you you're done. And this because you are - you're done again.
