FYI and possible interest, here is an article discussing a vulnerability in Apple Pay (Wallet) that potentially a hacker can get into. Only discovered in a lab so far. I do have Apple Pay (Wallet) set up in my iPhone, and almost never use it. Sprouts is the only store that I've been in that uses Apple Pay. The article recommends turning off "Express Mode" in the Wallet app, which the article said was turned on by default. I checked in 'Settings' in Wallet and mine was turned off for the two credit cards I have installed.
Maybe something for you do do if you have the Wallet app installed.
