With the Holidays fast approaching, there is a new security issue you should be aware of. Please watch out for people standing near you in the checkout lines with cell phones. These camera phones will allow them to 'photograph' your credit card. They will have your card number, your name, and the expiration date.

This is one of the fastest growing scams this year, so please try to be aware of your surroundings, and the people standing close to you. And please mention this to your friends, to help keep them safer also.
