I am assuming that the same PIN is used for calling card as well as Cash
advances from ATM's. If someone finds your card and tries to get a cash
advance then he only has three guesses before the ATM eats it. If he can
have his computer call in and brute force the PIN via phone then he will
probably be able to get cash off of your card.
