Hmm, I heard that over here (The Netherlands), they want to not use the number 9999 any more and use that as an emergency number. You'll get the money, the card'll be swallowed by the machine and the police will be notified of the event. Also, the little camera in the machine will pass everything through to the police.. I don't know if it's true, but it sounds like a good idea.
EDIT: Wait, now that I think about it.. That's a bad idea.. If someone finds your pass, they can just get a mask or something and get a one-time transaction for free..
Hmmm...
