Coin is a single device that can store and replicate all of a user's credit, debit, loyalty and membership cards through a mobile app. The Coin syncs with a user's phone and uses encryption to securely store card information. It functions like physical cards through a magnetic strip and digital display. The Coin aims to replace the need to carry multiple physical cards and is currently available for pre-order in the U.S. for $100, though some units are available at a discounted $50 price.
