For those card-collectors with too many plastic cards and bulging wallets, this digital Coin card may be the wallet-diet you need. It’s an eCard, but unlike any other smartphone payment systems, it lets you keep a real, swipeable card that will work with any retailer. It also has another added benefit – a Bluetooth connection that will notify your smartphone if you leave your card behind after a meal or too many drinks.
Coin is expected to arrive next summer, but you can save 50% by pre-ordering now. Coin Also has a referral program – earn $5 for every person who orders a coin using your unique referral code. This means if you get ten friends to buy a Coin, your Coin is free!
