Credit card signatures: Useless?
SpaceAdmiral writes "Everyone should remember John Hargrave's classic Credit Card Prank on Zug. He tried signing fake names on his credit card receipt, and no one seemed to care.
But that's nothing compared to The Credit Card Prank, Part 2. Can he draw obscene pictures instead of signing his credit card? Yes, it turns out. Is there any way of getting your signature checked? . . . Yes, it turns out. But you have to do an awful lot."
Most businesses don't charge the ATM fees (and usually request the bank doesn't either) because it doesn't cost them anything to process as opposed to credit cards which usually require a fee on their end for processing. You'll find that most places that accept debt/credit cards assume you are going to use the debt proceedure and try to steer you in that direction no matter what type of card you swipe.
