I can’t add my debit card on apple wallet

Hi kristiana99,

Welcome to the Apple Community.

Re:  "can’t add my debit card on apple wallet

How can i work out this ?"

The screen-shot shows the screen for adding store-cards, rewards cards etc...

ie: this is not the Wallet-screen for credit / debit cards.

You may need to sign your device in to your AppleID account:

and

All the best :-)
