Demo: Magnetic stripe reader

S3C used the Bus Pirate SPI sniffer mode to decode output from a serial magnetic card swipe reader. More at S3C’s site, and in the forum.

Regular Demo: articles will return next week. Demo: is a weekly series that demonstrates devices with the Bus Pirate. Come back next Monday for another new demo. Continue reading the demo below.
