Coin is a connected device that holds up to 8 cards and behaves like physical cards through a Bluetooth connection to a mobile app, allowing users to make payments with a small credit card-sized device on existing card payment networks. It has a screen to display the card brand and last 4 digits for verification and a 2-year battery life. The device was available through a $55 pre-order last year and beta testing with the first 10,000 pre-orders, and is now available for $100. Its key advantages are its portability, accessibility for use on existing point-of-sale terminals and ATMs, simple design and ease of use through the connecting mobile app.
