san francisco-based start-up coin seem to have found a million-dollar solution for replacing all your credit, debit, gift, loyalty and membership cards from cluttering your wallet or purse. ‘coin’ is a low-energy bluetooth connected device capable of storing all your card information into one place. developed with a specially engineered electronic magnetic stripe, users can swipe it like any other payment system, and works by simply flipping through a selection of multiple saved visa, mastercard or debit card accounts with the touch of a button.

the included mobile application allows you to add, manage and sync the cards on your coin. set-up is done by taking a picture of the designated card and swiping the device through a small smartphone attachment. for security, the system uses 128-bit or 256-bit encryption for all storage and communication. when paired to your smartphone, ‘coin’ can also alert you in the event that you leave it somewhere.

the coin mobile app can store an unlimited number of cards, however, a coin can hold up to 8 cards at a time
