Nearly all microcontrollers have existing PS/2 keyboard examples that would work fine with this swiper. For Ardiuno users, we tried out PJRC’s PS2_Keyboard library with great success — just check the ‘simple text’ example for which pins you can connect to on your ‘duino (on an Uno we used digital pins 2 and 3). We suggest our PS/2 adapter cable to make the wiring easy. Swipe any magnetic card and you’ll see the data appear in the serial terminal!
This reader will read and decode all three tracks of standard magnetic-stripe cards. It cannot write to cards, and cannot be modified to write to cards. We also have a two-track reader which is less expensive but does not read track #3.Wikipedia has a great article on magnetic stripe cards which will help you determine if you need a three-track reader or if a two-track reader is good enough.
