I have five different cards registered with Apple Pay. I’d like the last used card to be the default card. Right now it takes the first card in the list requiring multiple taps to select a different card. My expectation is that the last used card would become the default. Looks like Apple Pay doesn’t offer a card to be marked as default.
I was wrong about Apple Pay not offering a default card. You can set a default card within Apple Wallet app. Set the default by moving (finger swipe) the designated default to the bottom of the card list. The app will confirm the card as the new default.
Revolut really does use the default card as the default card in Revolut app. All good.
This Q&A should be entered into your Apple Pay FAQ.
