Whether or not it turns out to be a revolutionary device, Coin has our tongues wagging. This credit card-sized invention renders obsolete the want to carry around another piece of plastic—by storing a slew of relevant information from credit and shop cards within its slender profile. As the video (beneath) demonstrates, a intelligent telephone app permits the user to transfer content from every single credit card to Coin, after which Coin basically morphs into whichever card is selected by the user for a transaction. Goodbye bulky wallets so lengthy, rummaging around for the appropriate card. Eager users will have to wait till mid-2014 for a Coin, but pre-orders are becoming accepted now.
