The Apple Pay system is pretty cool! I used it last week when my dad and I were at a McDonald's restaurant. After politely taking my dad's shiny, new iPhone 6, I took my order. At first, Touch ID, wouldn't read my fingerprint, but once it did, the order was completed! The adoption rate is also great. I was at another McDonald's in a more questionable part of town, and I saw some teenagers use Apple Pay (I think) to order a large drink.
However, everybody is now saying that Apple "invented" this technology, which it didn't. However, NFC payments will hopefully be more mainstream (that is, if CurrentC is a total flop (which I'm sure it will be)).
