Time to say goodbye to thick wallets.
Coin is a card-shape device that replaces all your Credit, Debit & Gift Cards. It stores all the information within the device, and you can use the card exactly the same way as your current credit card. A small LED screen will allow you to view the cards stored inside, and set the active card. You may wonder if this card requires battery charging frequently? No. Battery of the first prototype lasts for 1 year.
Using Bluetooth LE, it even reminds you if Coin stays away from you for a distance with push notification on your phone. It will then deactivate itself. The retail price of Coin is US$100, now 50% off in pre-order period.
Coin is the future of cards. Agree?
