Hey all, I just got done reading this forum. I wanted to include my story as well. For the most part Apple pay has been a regular success for me, when i've used it where it's accepted. Just recently I had the issue mentioned above where the phone stopped responding to the terminal, as if there was no connection dtected. After doing a few troubleshooting steps resetting the phone and setting as a new device, having the SIm card swapped byl verizon. I finally called applecare and they diagnosed as the NFC chip having failed. I received great service and have a new iPhone 6 with the problem solved and the old one is on it's way back to apple via Fedex. Now that I think about it, the phone could have had internal failure going on with multiple things. As I was also having random battery drops from a good signal to instant dead, and occasionally the phone would get hot. The happy ending is, I have a new fully working phone and apple can deal with the defective one. Possible lemon from the start that slipped through Quality control so they can rebuild it and make it better 🙂
Excellent overall AppleCare experience .
