When Coin released the first video of its über credit card, the response was enormous. After 40 minutes, even though it was still just a prototype, 1,000 people had evidently forked over $50 for the super-slim electronic device that stores multiple credit card numbers and lets you use any of them with the mere push of a button. That took the company past its $50,000 pre-order goal. Just a few hours later, it had received a massive 20,000 orders for the device, which slides through checkout-counter card readers much like any other piece of plastic. Within two weeks, more than six million people had viewed the launch video that sent Coin viral. Apparently, there’s an awful lot of pent up frustration over the supposed problem of a wallet stuffed with too many credit cards.
