It seems like this would be much more useful if the front and back of the card were OLED screens, or something similar, so that you could toggle the appearance of the card. I feel like that would solve most of the problems people are suggesting here - i.e., it could replace driver's license, photo id's, wouldn't be a problem at bars that hold on to your CC, etc. Personally, I'm going to hold off on getting this until there's some functionality similar to what I outlined above, because currently this could only replace 2 out of the 5 cards in my wallet.
