I am currentLy working on my final year project titled "Design and Construction of a Smartcard operated pre-paid single phase energy meter". I have acquired an Arduino Duemilanove, which I intend to use for the entire project. I have enough info already on the emergy monitor section, pls I need more info on the arduino + smartcard aspect. Has anyone done this before?
A long time ago I used to interface smartcards to PC's over 9600 baud serial.
Probably a good place to start...
