Swyp Card
Like a couple other devices before it, Swyp Card is ready to replace all of the cards in your wallet. The metal card can store all your credit, debit, gift, and loyalty cards, is accepted at all the same places as a plastic card, and works with a companion app to track transactions and attach receipts. It also learns your purchasing habits, so it keeps your most used at the top, and thanks to a built-in display and buttons, it works just fine even if your phone's not around.
