Oddly enough, large EPOS systems have been subject to attempted fraud before. The old favourite was getting a crooked till assistant to accept stolen cheques in exchange for cash from the till, which is the same route you're trying to use.
As Peter points out that requires the shop assistant to press the
right button when taking payment.
If someone buys £3.50 of rabbit food and gives me cash then I can
pocket it while putting through a card transaction and the till will
still be correct. It requires a fair amount of slight of hand for the
customer to not spot it, especially if they need change, although they
are unlikely to be watching very closely.
