Friday, July 21, 2006: 1:00 pm (Area "A"): Curious what's on all those magnetic stripes in your wallet? Learn how magnetic stripes work and how you can use parts from your "junk drawer" to build a simple reader. Joe's reader design is easy to build and is capable of reading proprietary formats that most commercial readers can't. The software, which runs under Linux and requires only a sound card, does most of the work and is easy to tweak. Also included in the lecture will be a discussion about the New York City MetroCard and how its proprietary encoding was reverse engineered with this reader design.
