When I worked at Peter Piper Pizza it was quickly learned you could exit the program handling orders to get to a prompt. You could then swipe any magnetic card through the CC reader in the keyboard to see what was on it. You just had to swipe it at the right speed to get everything.
Most barcode readers / magnetic swipe readers work with drivers that simulate keystrokes... and that's why the point at which you're allowed to scan the card just happens to be same screen at which you can type the number in manually. The device just needs to be configured for what sequence of enters/tabs/etc. to enter after a scanned number.
For example, a credit card reader at a POS unit would be set to output the first 16 characters on the card, and then maybe [tab] to exit the entry box and [enter] to clear the "Are you sure? Y" prompt. Hook the same reader up to any free-text entry screen, and the number ends up in plain view.
This would be a neat way to store combos for fighting games... almost like the attacks in Battle Network Rockman.EXE for GBA... It would certainly lengthen the life of many controllers...

At ${ORKPLACE}-3, following budget cuts, I was put in charge of inventory and production (which was better than being laid-off because your project gets cancelled - also, it enabled the company to fire the old inventory guy who was not doing a good job, and in all the people in the place, I was the only one trusted enough to do it - the most important partner didn't even trust his other partners!!!).
I used to work for a POS Helpdesk for an *unnamed* gas station/c-store. We could always dig through the log files to read what sort of input was recorded from a cardswipe on a CC#. There are actually several (usually 2 readable) tracks on your average CC.
The data on the MS of your major CCs are usually <15-16 digits - ala your CC #>=<exp date>
I used to work for a company that developed simple access control systems. You would be supprised how many people swiped their credit cards through the reader. All invalid card numbers were logged. We had equipment to print & encode our own cards so it would have been easy to produce forgeries (without the hologram though).
