Grocery Store Security

While I was at the grocery store this evening I saw some poor woman being run through a bio-metric gauntlet. She had to have her picture taken and multiple fingerprints scanned in order to cash a check. I didn't see any retinal scanners, or voice print identifiers, but perhaps she'd already passed those. Anyway, please don't mention this stuff to the TSA; it's already a major inconvenience to fly.
