Beware: Sophisticated 'skimmers' out to steal your card data at ATMs
Don't fall victim to a 'skimmer'
Bob Kierstead of the U.S. Secret Service offered these tips for consumers:
Don't be in a hurry: When using an ATM, look at the card slot to make sure everything appears normal and there are no wires or anything else unusual showing. Kierstead suggests giving the faceplate around it a wiggle to make sure it's secure and not a facade.
Look for anything unusual: Check around the PIN keypad and make sure nothing appears to be amiss. Are there any objects nearby that could hide a tiny camera?
Conceal your PIN: Kierstead suggests using your other hand to cover the keypad while you punch in your personal identification number.
