Someone must have used one of those devices to swipe your debit card and took out the money. This happened to my DH about 5 months ago. Most likely it was a resturant, the server walks away with your card and swipes it on a device that can be purchased over the internet, then they sell the info and a new debit card is made and the person takes your card to the ATM and withdraws cash. Someone took out $6,300 dollars cash from our account (the ATM was in a casino). We did get the money back in about 10 days.
