I've just got my dev kit so a lot of tinkering to do but my first 'problem' is how to go about generating random numbers. Not ordinary random numbers though.
What I'm trying to do is generate a random number that changes on every card insertion in the balance checker, and have a PC program that does the same.
The idea is that a user goes to a web site and types in the number on their balance checker, the PC side matches this number (or applies an algorithm to it) to determine if this is a valid number for this user at this time..
First of all is this possible, and secondly have you got any hints as to how to go about it?
