...so you keep the one you primarily use in the front of your card slot in your wallet, and the one you don't use often behind your other cards.
Apple wallet solves this in a similar way, letting you arrange the order
Yes, I can try to memorize the order of the cards. What a lousy workaround, and absolutely no reason to defend poor UI design.
I didn't know I could do that, so I just gave it a try.
First instinct, double tap the side button to open Wallet. Couldn't rearrange the cards there. So,I opened Settings app and couldn't rearrange the cards there. Finally, I opened the Wallet app and found I could rearrange cards there, though there's no visual indicators that I can. I accidentally changed my default card on the first attempt.
