Coin is a swipe-able connected device that looks just like a credit card, and contains all your credit, debit, gift, loyalty and membership cards information in one place. Press a button and swipe, and it's your debit card. Press again and it's your business credit card. Press again and it's your library card. That's awesome, but here's the best part: the credit card automatically notifies your smart phone if you accidentally leave it somewhere. No more accidentally leaving it with the signed receipt at the restaurant.
