Billy Hoffman

Billy says he is too curious for his own good. "I like to take things apart, see how they work see their shortcomings, and try to make them better." Living in Atlanta gives him plenty of time to pursue outdoor activitues as well as seek input from his friends about possible technological advances he's working on. Some of Billy's current projects include a self-destructing, some radio-frequency ID stuff, blogging technology, and spyware-cracking software. He's graduating this spring from the Georgia Institute of Technology with a computer science degree - anyone hiring?

Adding Multi-Track Capability to Your Magnetic Stripe Reader
I paid $30 for a Omron V3A-4, which is a single-track reader. But you can modify it to read all three standard magstripe tracks, for free!
