Okay, so I've seen ads for this all over. You can pre-order coin now, and they ship summer of 2014. Coin basically holds all of your cards (credit and debit) in one. You can slide it like a regular, but it also sends alerts to your phone if it's away from your phone to make sure you didn't leave it behind. I like this idea more than I like something like Isis mobile wallet, because if your phone was lost or stolen so are your credit cards. This however, is just a nice place to keep your cards together.
Once Coin goes on sale it will be $100 but if you pre-order its 50% off. Learn more about coin here, or check out the video below.
