Two things strike me about this.
1. What a cack-handed way to run a coffee machine, the bank transaction charges probably cost more than the coffee.
2. How hard would it be to surreptitiously whack a little bit of custom hardware in the line to return the appropriate approval. I'm sure there is a lizard around here somewhere who could help.
3. Whats the betting that the coffee machine is not in fact running 3DES or some similarly strong encryption routines meaning that the bit of kit from 2. could also be used to harvest card details.
Ok that's three, but the third one came to me as I was writing number two.
