LoopPay hasn't gotten the knack of making attractive and non-slippery cases, but the removable CardCase is a far smarter concept than the older ChargeCase. If you already have an iPhone 6 or 6 Plus, CardCase gives you the ability to use credit cards that Apple Pay doesn't yet support, like Discover, and charge at stores that are turning away Apple Pay.
The CardCase won't be available for the iPhone 6 and 6 Plus for a few months, but if you don't care about the goofy case and don't mind carrying the card in your pocket, then the CardCase for the iPhone 5s, shipping now, works just fine. And if you're an iPhone 5s user jealous of Apple Pay on the iPhone 6, the CardCase is currently the best option around. At least until Coin and Plastic show up.
