Once I add my debit card to Apple Pay, how can I suspend the ability to make payments or remove Cards from my device?

To remove your Debit Card on iPhone 6 or later, iPad Air 2 and iPad mini 3 or later, select “Remove Card” in the “Wallet & Apple Pay” section of your device “Settings” or on the back of your Card in the Wallet app.

To remove your Debit Card on Apple Watch, go to “Wallet” on your Apple Watch device, select your Debit Card then hold and tap “Delete” to remove your Debit Card. Additionally, you can remove your Debit Card using the Apple Watch app on your iPhone. Open the Apple Watch app, select “Wallet & Apple Pay”, then select your Debit Card and navigate to the bottom and tap “Remove Card.”
