[ned]’s HandySwipe is a portable magnetic card reader. It runs on 4 AA batteries and collects data from track 2 cards. It uses a PIC 16F688 and displays the card’s data on a small LCD. It can store up to 50 cards and dump them in CSV format. It will also output the raw bitstream for use with Acidus’s StripeSnoop. Ned’s project write up is pretty interesting since he covers using a logic analyzer while swiping a card and driving the LCD with only three pins using a shift register.
