Hi Mike, No need for DOS compatibility - the data is custom. Flash or EEPROM makes no difference - non volatile is what I need. The smart card I've seen so far are quite small... 2K-bits (256 bytes) I need about 16K-bytes or more to store all of the data required. The data doesn't change very often. (maybe every 30/60 days or so) Needs to plug into customers equipment with no hassles at all.
