Can I remove my card from Apple Pay?
You can remove your card by selecting “Remove Card” in the “Wallet
& Apple Pay” section in your device “Settings” or on the back of your card
in the Wallet app by tapping on the symbol.
You can also visit www.icloud.com/settings to remove your
card or use the Find My iPhone app to temporarily suspend or permanently remove
the ability to pay with your cards on your device.
When adding your card, you can choose to add the card you
already have on file with iTunes® or add new cards by manually entering your
card information or taking a picture of your card.
