You have a credit card with no personally identifying information other than your name on it? No card number, no expiration, no CVV, no phone numbers, etc? You have a credit card with no ink on it, just laser engraving? You have a credit card that is made of metal? Not with a metal core and layers of plastic on top of that, as several of the cards in my wallet are, but completely made of metal? Which card is this?
