This is a fantastic looking ATM machine. It takes notes, spits out change and can keep track of different accounts using the Codadex RFID sensor.
One of the coolest features I think is the fact that it scans the banknotes as they go in with a light sensor, and creates something like a histogram. It then compares it with a 'known' banknote to figure out the value.
Another nifty mechanism is the numerical keypad, which pushes a different coloured tile in front of a colour sensor.
