I wonder if it's something like a keylogger... maybe something as simple as pulling the plug out and putting something inline.

However (as mentioned previously) it would be pretty straightforward to obtain an identical terminal, insert a logging circuit inside of it (connected directly to the keypad and card reader), and replace the one at the register with the hacked one. Then all that's necessary is to recover the modified terminal at a later date and download the logged numbers.
