First thing I noticed too, as I have multiple cards from the same bank. I also noticed they show you last digits of the ... CARD number, not the account number which would be tremendously more helpful. But I figured out you can put little icons on the cards. Which my bank did automatically for my business account. I added a little person icon for my personal account. Maybe bank specific though but definitely super dumb that you cannot label them yourself easily in the wallet app.
That's ridiculous. The card number has nothing to do with the account number.
