Many of us used to carry a lot of credit cards in the past. Since your iPhone lets you make payments easily, there is no need to do that anymore. Want a separate device to manage your credit cards? Coin can help. It is a Bluetooth-enabled device that holds up to 8 cards. You can switch between cards with the press of a button. To get started, simply add cards to the mobile app and sync them to Coin via Bluetooth.
Coin unlocks when your phone is nearby. When it is not, you will need a Tap Code to unlock it. It lets you track the last known location as well. The device will ship in August.[where to get it]
