I need the basics. I have a card added to Apple Pay, but honestly, I have never had any luck using it on the watch OR phone. Granted there aren’t tons of places around here that actually use Apple Pay, but I’ve tried it at the local Subway a few times and basically I wind up wasting people’s time and feeling like an idiot. What am I doing wrong here? Also, can I add more than one card, and is it still gonna be faster to use if I have to get in and pick a card? I just need the lowdown.
