There is a document from Stephane Bausson
(http://www.hut.fi/Misc/Electronics/docs/cards/iso7816.txt, and beware
because there is a lot of versions, my link is the 1.00 but I've seen the
2.x, try altavista) that explains the iso7816 about the pin meanings,
timings and voltages, etc. Is mainly oriented to the telecard world. About
the chip in the smartcard, what you read it is dependent of the cpu. By
example, a telecard has its own cpu, so it has its own memory map, and a
visa electronic has other cpu, so you can read it the same way, but not
interpret the contents.

hope it helps, keep on PICing.

PS For 'the bad boys': is VERY hard to clone a telecard or smartcard. Better
focus efforts in other direction.
