And that's one of the reasons I use a credit card instead of a debit card. I'm sure that at the end of the day (theoretically speaking of course) that the bank will make your account "whole" and return the balance to what it should be. But, I'd much rather have fraudulent activity hit my credit account than my cash account. There's time to react on credit, where as debit takes my money right away.
FWIW, my credit cards have been hit several times by fraudulent activity. The credit card company has always been on top of it (many times catching the activity before we did) and we've never been out a penny.
