With all the cards we carry in our wallets — multiple credit cards, debit cards, bank cards, loyalty cards, membership cards, gift cards — we run the risk of looking a little like George Costanza. But with Coin ($100), we can finally start slimming down our every day carry to something a little more manageable. This connected device (shaped and sized like a credit card) lets you scan all the cards you typically carry in your wallet, and then leave them at home. It works just like a regular card, letting you swipe it the same way you normally would, and lets you easily swap which card you're using at any given moment. Manage your collection of cards with their mobile app, and never lose track of your Coin thanks to low-energy Bluetooth alerts.
