After a year and a half of development (and with some more yet to go), the result is Swyp. It’s a super thin metal credit card with nothing more than a small front display and a pair of buttons that can become any credit card in your wallet. It also does loyalty and gift cards. That’s not a new idea — see Coin and Plastc — but Dhodapkar’s company aims to sell one that’s more durable, and in Plastc’s case, markedly less expensive. It also looks really damn cool.
