The photos do not appear directly on your room card, but are generated onto a computer. When you leave or board the ship, the card will bring up your picture to match with what you look like. If there's a question, that's where the driver's license will come in. Believe me, we've seen it happen to a man in front of us. We were very uneasy with the whole thing, as he had (2) different room cards with different names, neither of which was his. Hopefully he never got on the ship. Security will be tighter now that we are in heightened alert.
