I rarely get excited anymore about new gadgets, but the just unveiled Coin is getting me excited. This is really cool. Watch the video below - it is the best way to understand it and see how beautifully it is executed.
San Francisco startup Only Coin just launched its first product. The Coin is a smart credit card size gadget that replace all your credit cards. You can store your cards on the Coin and select the one you want to use on the card. The smart technology changes the data on the magnetic strip to simulate the card you selected. The beauty is that there is no need for NFC or other new infrastructure that other wallet systems require. Everything stays the same, but you only have to carry around one card in your wallet.
