Startup Coin is looking to lighten your wallet (and in a good way.) Using a mobile phone and card reader, Coin can store an unlimited amount of cards within its app, and then transfer up to eight of those cards onto your Coin card, letting you leave your other plastic at home. It will store credit cards, reward cards, gift cards - any card with a magnetic strip.
The card syncs with the mobile app wireless using Bluetooth Low Energy (BLE), a new technology that has been opening the door for innovation among creative product developers. Many new gadgets are benefitting from this technology, including fitness trackers and smart watches.
Coin is available for preorder now, and will ship Summer 2014.
