How to remove my debit card from my iPhones

Hey nuzhat96,

Thanks for using Apple Support Communities. Are you trying to remove the debit card from your Apple ID payment method? If so, these steps can help: Remove a payment method from your Apple ID - Apple Support

If instead you're looking to remove the saved debit card details from Safari's AutoFill feature, you'll tap Settings > Safari > AutoFill > Saved Credit Cards. From here choose the card you wish to delete, then Edit in the top right corner, and then "Delete Credit Card". A bit more information on this feature can be found here: Automatically fill in your information in Safari on iPhone - Apple Support

We hope this helps.

Take care!
