In discussing our upcoming trip, I mentioned to my DS (age 26) about the finger scan. This "intrusion" bothered him. He is very much a Libertarian and was really quite annoyed about it. Is he just a paranoid New Yorker or do others find this (in his words) a bit orwellian?

Anyway since then when the scanner lights up for my print I try to do it quickly so I don't have to explain myself. Does anyone know if it really matters which digit you use?
