The sample card I have is an i2c device. Farnell call them a Smart Card but they're simply an 256 byte EEPROM in a card format AFAICT. I don't have the datasheet for it yet. It's made by Comtech from what Farnell says. I downloaded some ISO7816 data last night but that seems to be for the "real" Smart Cards. The Farnell cards are about AU$6 and the contact frame about AU$15. This is the price range I'm looking for. The system only has 6 rooms that need simple access control.
