We saw a close-to-final prototype, which has a few rough edges, but the final design will be sleeker, with three clicky buttons in the lower right-hand corner, a logo in the top right, and the display on the bottom left. All your cards show up on the screen along with the nickname you gave the card, the last four number on the card, the expiration date, and CVV number. There will be a space for your signature on the back, and an EMV chip, which will become standard in the United States in 2015.
