Payment of balance owed
How do I pay off the balance of my credit card?
iPhone 6s, iOS 14
If nothing is due, but you have pending transactions:
Go into your iPhone's Wallet and tap your Apple Card to view it.
Tap the "..." information icon on the top-right
Tap "Schedule Payments"
After tapping "Continue" Select how you'd like to schedule your next payment, and follow the succeeding prompts.
If you have a balance:
Go into your iPhone's Wallet and tap your Apple Card to view it.
There should be widget, under your card and to the right showing you what is due. Tap it.
It should give you options on how to pay off the balance.
