True or False. To protect yourself from identity theft, don’t sign the back of your card.

False. An unsigned card will cause you trouble at the cash register — you’ll have to show photo ID for the cashier to accept your payment. Besides a thief could simply sign your card himself for unauthorized purchases, and then the card signature would match the signatures on the receipts.And don’t do this either: I was rollerblading one day in Palm Springs and found a debit card in the street. When I got back to my car, I turned the card over to get the 800 number on the back so I could call and report the lost card… and there was the PIN written in the signature block! If someone else found it, it could have been a far different outcome.
