Remove cards from Apple Pay and Wallet in Settings on iCloud.com
If you have set up credit, debit, or prepaid cards for Apple Pay, or student ID or Express Transit cards on your devices, you can remove the cards in iCloud Settings.
In Settings on iCloud.com, tap a device listed below My Devices.
If you don’t see the My Devices section, your account just has access to iCloud web-only features. To gain access to other iCloud features, set up iCloud on your iOS and iPadOS devices or Mac.
Below the list of cards on the right, tap Remove or Remove All.
Credit, debit, and student ID cards are removed even if your device is offline. Express Transit cards are removed the next time your device goes online.
If no cards are listed, you haven’t set up Apple Pay or other cards on your device.
To add cards back to the device, see the Apple Support article Manage the cards that you use with Apple Pay.
