What if you could replace your handful of credit cards with one super card? Meet Coin, one thin card that stores an unlimited number of payment methods. Simply swipe your cards on a credit card reader(included) and all the data is stored in the Coin app on your smartphone. You can then leave your cards at home and choose which card you want to use from the Coin card LCD screen. It works as a regular card, allowing you to swipe it the same way you normally would, and for security purposes, it alerts you when Coin is apart from your phone. Coin is now available for pre-order online and will support both iOS and Android.
