Sadly there are lots of security holes out there. Hannafords (an east coast grocery chain) just revealed that hundreds of thousands of card #s had been obtained by hackers. How? There was some kind of vulnerability in Hannafords' system, and the card #s were being captured during the card authorization process. Who would have thought that swiping your card at the grocery checkout would put your information at risk? My card company just closed my account and sent me a new card because my card # was compromised (though luckily I didn't get any unauthorized charges).

I don't use my debit card for anything other than local ATMs anymore. I know that Visa/MC branded debit cards now have protection for unauthorized purchases, but it's still your bank account in the meantime...

Sorry this happened to you and good luck.
