The future of money has arrived, and it's called Coin. It looks like a credit card. It's the size of a credit card. It swipes in credit card machines. But it holds the information of up to eight of your debit, credit, rewards, or gift cards. And you can switch between cards by simply pressing a button. The new product, launched recently, promises to change the way consumers spend money in a secure and efficient way.
The key technology is a Bluetooth signal. To load information from your different cards, just swipe them on a card reader into your Apple or Android phone and take a picture of the card. If you're too far from your card—like, say, you leave it at the restaurant—your phone gets a notification. And the Coin's battery lasts up to two years.
People use cash less. Receipts are redundant with online banking. And products like Coin allow people to pay digitally, instead of with a physical credit card. Could the George Costanza wallet be a thing of the past?
