Magnetic Credit Card Stripe Emulator

Final project for CPE 329 embedded systems course at Cal Poly.

System:
128x64 Graphic LCD w/ parallel interface
Magtek Track 2 magnetic reader
AVR 2560 microcontroller
electromagnetic 'spoofing' wand w/ amp

The user scans a credit card, or other ID type card, the data is collected and displayed on the LCD. It can detect what type of credit card, state of driver's license, and Polycards.

The user then can press a button on the wand, it will power a simple common emitter amplifier to pulse current through a coil wrapped around a piece of sheet metal (~5 layers of 30 turns each). To send data through the wand it must first be converted into BiPhase MarkCode from the original data we read from the reader. This creates flux changes similar to the real credit card's track and fools another reader into thinking a real card has been swiped.

An extra reader is used to display the cloned card's data on screen in notepad. Note this reader spits out simple ASCII keyboard characters, the actual reader used with the microprocessor is much more low level. It utilizes strobe, data, and card present lines coming from an amplifier on the reader, and must be heavily processed to convert it into legible ASCII data.
