Coin is your credit card on steroids, it has the ability to hold all your cards (including gift and loyalty cards) and lets you use them all on one single card. This is done by attaching a card reader to your smartphone, taking a photo of your card, and it’s immediately available on your Coin card. Multiple cards are accessed simply by pressing a button on the card and Coin tells you which card you’re using on the card’s display and if you happen to leave your card behind, it uses Bluetooth to notify your phone if your card isn’t in your wallet. You can pre-order a card today for $55 and once it hits production next summer the cards will cost $100.
