- I've also heard that eel-skin wallets frequently have magnetic
- latches.

- All this mag stripe stuff seems overly complex to me. I've
- often thought we could do this more simply with bar codes. Just print
- the bar code on a clear card. Use an opto interrputer module to read
- the card as the person slides it between the LED and the opto
- detector. I have not experimented with this. There may be a problem
- with LED spot size requiring rather large bars, but it does seem that
- something like this could be done. Much simpler than reading off a
- magnetic head, and it's permanent. Do credit cards need read/write
- memory, or is ROM sufficient?
