Coin, a startup out of California, has announced their first product: an all-in-one credit card payment system that will let the user switch which credit card or account they want to use at any given time.
At first glance, it just looks like a thin, black card with a digital display, the same size as a credit card. But it is an impressive little device that accesses up to eight different credit, debit, membership or debit cards at once.
Users can quickly switch between cards at will, then swipe it through any regular card reading payment machine at retailers around the world. The display screen shows the last four digits, expiration and CVV (security) number of whatever card is currently selected.
