Credit card fraud (Score 1)

Given the type of purchase you were making, anime DVD's, I can see where there might be a problem with kids ordering merchandise without parental consent, and that is probably what the merchant is trying to stop. (However, any kid can easily get a picture or a photocopy of mom and dad's ID if they wish to.) If the parents call in a dispute for an unauthorized charge and the store can produce a photocopy of the card and a photo of the card holder, the store is in the clear. I think the store is just protecting itself. In credit card fraud rings all that is needed is a blank piece of plastic and a credit card number. If this store is part of a ring having your card number is enough. A picture of you isn't going to give them any added benefit of ripping you off.
