Entrepreneur Kanish Parashar has an ambitious goal: He wants to replace every credit card, gift card and loyalty card in your wallet. To do that, Parashar has founded a company called Coin.
Unlike other companies like Square and PayPal that are trying to do the
same thing with mobile apps and proprietary services, Parashar plans to
use something quite different -- something that looks like a credit
card.
Coin is a Bluetooth card that can be used in the place of
the cards in your wallet. Any card with a magnetic strip can be added to
Coin, and a button on the front allows you to easily swap between
cards. With each button press, the magnetic strip on the card
essentially becomes your card of choice, giving you the ability to carry
around your whole wallet in just a single piece of plastic. A tiny LED
screen displays the last four digits of the card you're using along with
its expiration date.
