iPhone 8 Apple Pay stopped working , but works on iwatch ?

Hey Stevoxxx,

Thanks for the update. Since you are able to add cards, and the problem begins when you use the fingerprint scanner, it may be an issue with Touch ID. You may want to try enrolling and using a different finger.

"Follow these steps. Try using Touch ID after each step:

1. Make sure that you have the latest version of iOS.
2. Make sure that your fingers and the Home button are clean and dry.* For the Home button, use a clean, lint-free cloth to wipe off any dirt or debris.
3. Your finger should cover the Home button completely, touching the surrounding metal ring. While Touch ID is scanning, you shouldn't tap too quickly or move your finger around.
4. If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring.
5. Go to Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on, and that you've enrolled one or more fingerprints.
6. Try enrolling a different finger."

If Touch ID isn't working on your iPhone or iPad

"Manage your Touch ID settings

Go to Settings > Touch ID & Passcode to manage these settings:

• Turn Touch ID on or off for Passcode, iTunes & App Store, or Apple Pay.
• Enroll up to five fingerprints. Each new print might make fingerprint recognition take slightly longer.
• Tap a fingerprint to rename it.
• Swipe to delete a fingerprint.
• Identify a fingerprint in the list by touching the Home button. The matching print in the list will be highlighted briefly.

Press the Home button using Touch ID to unlock your device. To unlock your device using Touch ID without pressing the Home button, go to Settings > General > Accessibility > Home Button and turn on Rest Finger to Open."

Use Touch ID on iPhone and iPad

Take care.
