Again, bull. Jeesh, you should go into the manure business. You'd be rich
in no time.

These poeple do -not- use modular arithmetic. The machines and the
software they run does. They put a card in (maybe) and enter a number or

Further, if they believe these systems are foolproof then they're
mistaken. They are -hard- to crack, not impossible.
