"Coin" is a low-energy Bluetooth connected device that is capable of holding all your credit, debit, gift, loyalty and membership cards in one place. Instead of carrying all those cards in your wallet just carry your Coin which works anywhere those cards are accepted. You can feed the card to the coin simply by taking a picture of the designated card and swiping the device through a small smartphone attachment. When you want to pay, simply choose the card by tapping the button on the 'coin'. ‘Coin’ also alerts your phone when you accidentally leave it somewhere.
