Hi everybody, I want to designe a lock system with credit cards as keys. As far as I know, there are three tracks on these cards with different density and different codes. One of them is using 5 bits, the others 7 bits and perhaps they are called ISO1, ISO2 and ISO3. I would need the exact codes or at least hints, to where I can find them. Any hints are welcome, prefered by email to fs_reise%rcvie@tuvie or tuvie!rcvie!fs_reise. Please try more often, until I confirm. Thanks in advance. Greetings from Vienna/Austria CR
