microcontroller sim
Hello
I have many 64Kb Sim cards from GSM phones. These cards have 64Kb for custom Java programs. I would like to know how to interface these cards to a microcontroller, so to write and read information to the card. I hope somebody can help me. My idea is to load a program in a sim card, and when connected to the MCU, the MCU upload the program to its flash and starts running the new program. The MCU may be an Atmel AVR or a Philips AMR7.
Thanks
Ezequiel
