Coin is going to be incredibly cool when it launches. An electronic credit card that stores all of your credit cards, and let’s you swipe any card just like normal. It’s not pushing the actual physics of credit transactions in a new direction, but rather giving consumers a tool to keep using existing card-swiping transaction behavior with a new piece of gear that stores all of their cards. Now, if only V2 of coin could include a mag swiper, NFC chip, chip&pin chip, and e-ink QR code/barcode display, it could be used as the end all, be all card in your wallet.
