Right. And if I remember correctly, a swipe is almost exactly the same as typing in the numbers on the card. Not sure if it's still the case but years ago I had a job where we had some "swipe" devices which hooked up to a standard PS/2 keyboard port (to give an idea of when I'm talking about). If you opened Notepad on a PC and swiped a card it just typed out the relevant digits as if you'd keyed them in.
