My Apple Payment Card is declined, What Should I do?
If a payment card that you use with Apple Pay is declined or doesn't work when you try to make a purchase, check to see if your card can be used with Apple Pay.

- On your iPhone, open the Wallet app.
 - On your iPad, open the Settings app > Wallet & Apple Pay.
 - On your Mac, choose Apple menu  > System Settings (or System Preferences), then click Wallet & Apple Pay.
 
 - Select your payment card.
