I saw Zarouth's excellent program that had a 10 digit code to open a door and this got me thinking would it be possible to use this to make a fully automatic chip and pin machine. I am pretty rubbish with computercraft but thought you could link a player detector to his program and make it so that when you click the player detector the computer asks for your code which you then enter. If correct your cash is displayed onscreen if not correct the program resets. Is this possible?
