I enjoy using Apple Pay, but there are a few things that Apple needs to do to improve its adoption:
1. Add Face ID support for masks. If I need to wear a mask in a store, then I prefer to use physical credit cards because it's really annoying to wait for Face ID to fail and then unlock my phone with the passcode.
2. Put substantial effort into supporting driver licenses and IDs of all 50 states along with employee IDs, student IDs, gift cards, etc. Make it easy and proactively get organizations on board with this. My physical wallet has a bunch of cards in it and I would prefer not to carry my wallet around, but I still need to carry my wallet around if my iPhone doesn't support even just one of those cards.
3. Improve the wallet UI. If I want to use a credit card other than the one chosen as the default in my iPhone, it's annoying to scroll and find it in the UI. I would prefer a grid UI or something faster to move through.
4. Find a way to support Apple Pay at restaurants and other venues (e.g., gas stations in NJ) where a worker traditionally takes your physical credit card and goes elsewhere to process your transaction.
