How do I add a 2nd debit card to my apple wallet

Hello, first go to the wallet app on your phone. Then on the top right corner there's an add icon. Just press that, select "debit or credit card" then press continue. Then add card with a picture or manually, just like the first card. Once you do that you continue and press next. It's going to ask you to agree to the contract, then from there you add the second card.

hopefully this helps. :)

You add a second debit card the same way you added the first.
