Issue with Apple Pay and QR code scanners
Recently, I was trying to use my boarding pass, basically a QR code on my iPhone7 and every time I tried to check in, the phone defaulted to Apple Pay. There was no way to get around this. I also discovered that the Apple Pay is activated when around almost any near field reader, e.g. contactless cards for payment etc.
