Edd card for apple pay

Welcome to Apple Support Community!

I would first check if the bank for that card is a supported participating bank for Apple Pay.

Apple Pay Participating banks: https://support.apple.com/en-us/HT204916

If it is listed in that resource above, you will have to follow the resource below on how to add the card.

Setup Apple Pay : https://support.apple.com/en-us/HT204506

When you add your card, it may prompt you to verify payment method to use with Apple Pay.

You will need to contact the card issuer for them to approve the card.

Apple Support cannot activate or verify your payment method for use in Wallet.

Hope this helps ;)
