| If you use 8051 uart , take care the divide 372 problem . The most reachable dividid is 384 , but for some critical test for compliant of iso7816-3 . It can fail sometimes .

| The cost of the entire card is under $1 US with the gold plating on the contacts being the most expensive component. I would suspect that whatever processor is cheapest and has internal nonvolatile memory.

Do you really mean a processor-card and NOT a memory card? Manufacturing cost or selling price ? Here in Europe the selling price for a processor-card is - depending on features e.g. crypto-coprocesors - about more than 10 Euros, also in higher quantities. It would be really interesting if you can provide a link to such a cheap card.
Thanks,
Mik
