I've read a lot about these skimmers popping up at ATMs... protect yourself. A Boing Boing reader describes his experience..
"This past weekend I went to use the local WaMu ATM to get some cash money. When I walked up to the ATM something struck me as funny…I couldn't quite put my finger on it but the card reader didn't look right, like it wasn't completely attached. I grabbed and pulled at the card reader and, lo and behold, it came off! It was actually a card skimmer attached to the ATM over that actual card reader. On the back there is a battery, flash memory card, and a mini USB port – it was set up so that ATM cards would first go through the skimmer and then into the ATM itself so you'd never know the difference. Fortunately I'd seen a news story about this sort of thing a couple of years back and have been paranoid ever since."
If the card reader on an ATM seems like it doesn't belong—and especially if it looks fragile or misaligned—go to another ATM. And let someone at that bank or store know that they may want to double-check their ATM for skimmers.
