**Cue's Limbo music** How low can it go, how low can it go?
Seriously though, think about it, the print cards are on file, there might not be any reference to why the cards are on file but they might just come across them and put them back in the comp. It would be erased within the alloted time but if it just happens to be that day that they were put in...
Actually, I was arrested once
*, several years ago and there was absolutely no physical card involved, they stuck my fingers right on the print scanner and took digital (no pun intended) copies of my prints straight into the database... now add about 70 years of tech to that, and I really don't see ink-pads and cardboard coming anywhere near a prisoner.
*Bunch of bull-crap that started because some %#$*ing idiot of a shop owner waited over two months to cash a small check I'd written him and I'd closed the account in the mean-time.
