This company has developed a piece of hardware (shaped exactly like a credit card), that can actually be swiped in credit card machines, that holds all of your personal credit, debit, and gift card information. You switch between cards using a button on the device, you add them to the card via a phone app and an attached card swiper, and as it's linked to your phone, it'll alert you if you get too far away from the card (in the case of leaving it on a table and walking away, or forgetting your wallet on the way out of the house, for example).
