Credit card, debit card, gift card, discount card, member card, second credit card, your wallet is full of plastic.
Coin envisions a card for all. Yesterday seven people presented in San Francisco one all-in-one card, called Coin. The card may include all your financial information. The information can be transferred from any other card that you have your wallet through a dongle that is plugged into a smartphone. The device is available for pre-orders.
The card Coin is built with a patent and runs on a battery that can last up to two years. The battery feeds a small screen showing the amounts of your cards, along with their expiration date.
