After months of delays, the payments device startup, Coin, has started to ship its card. This announcement is after almost 12 months of delays and a number of development issues. Competition has entered the market with similar cards and the release of Apple Pay hasn't helped either. Coin might have missed its opportunity to become the market leader and the company's backers should be ready for further frustration with the arrival of EMV this fall (Coin is not EMV compatible).
