A Card For Your Cards

Today everyone (okay, a certain kind of 30ish white guy) is losing their minds for a new startup thing called Coin, which offers a solution to a problem you may not know you had: too many credit cards to carry around at once!

Coin is a genuinely kind of cool bluetooth credit card that holds all the date for your other cards inside of it (or connects to the app on your phone that holds all of your data), so you just decide which card you want to use for each transaction, push a tiny button on the card, then swipe.
