We’ve all been there, that sickening feeling as you reach for your back pocket, only to find your wallet gone. A frantic search turns up nothing. You feel sad. But you wouldn’t feel that sad if you had photocopied the contents of your wallet. Then you would have a legal copy of your license to use until it got replaced, and all your account numbers and the phone numbers you need to call for replacements. So take a second this weekend to pop your wallet into the photocopy or scanner and keep the paper in a safe place. You might be very glad some day that you did.
