I went out to a McDonalds today at lunch an hour before this guy. I didn't record the experience but mine went much smoother than his even. I did not have the Phone awake or the app on. As I moved the phone closer to the NFC, I had my thumb already on the button so it scanned, opened the app and gave me the verification check instantly without having to do anything else.
After that I decided to try Petco across the street but I had a less positive experience. When I trie to pay for my dogwood there, as I approached the NFC terminal, my phone vibrated and I got the verification check but the cashier said nothing went through. I tried again and got the same thing. Then she said that their NFC terminal hasn't worked in years. Obviously there was a hardware handshake but their POS software must need an update for Apple Pay and probably any other NFC payment system.
But it's interesting (and a little scary) how I got a confirmation twice even though no purchase ever went through. What's preventing them from lying to me and telling me to run it again? I can only see the receipt if I look in my info box in Passbook. Otherwise, I'm at the mercy of the cashier who could be lying.
Any thoughts?
