Check these first
Do not assume the cause from the symptom alone. First determine whether the issue affects the whole phone, one app, one connection, or one accessory. Work from low-impact checks toward recovery or repair.
- Confirm that the phone, region, bank, and service support NFC payments
- Check card expiry, suspension, and identity-verification status
- Remove cases or card storage that may interfere with the NFC antenna
Narrow down the cause
| Scope of the issue | Where to check next |
|---|---|
| Only one app is affected | Check app permissions, updates, storage, cache, and reinstall options |
| The whole phone is affected | Check restart, system updates, free storage, and system settings |
| Other devices have the same issue | Check the network, service, charger, or accessory |
| The issue began after a drop or liquid exposure | Avoid repeated power or charging attempts and contact official support |

Safe step-by-step process
Complete one step at a time and test after each change. Do not change several settings at once.
- 1On Android enable NFC and contactless payments and select the default wallet. On iPhone check the card status in Wallet.
- 2Unlock and authenticate the phone, then hold the correct phone area steadily against the terminal symbol for several seconds.
- 3Remove thick cases, magnets, metal rings, and stored contactless cards before testing again.
- 4Try another compatible terminal or location to separate a terminal problem from a phone problem.
- 5Before deleting a card, confirm re-enrollment and identity requirements, then update the wallet, OS, and card information.
- 6If several cards fail at several terminals, report the exact time and error to the payment service, card issuer, and manufacturer.
Actions to avoid
- Repeating payment attempts without checking for duplicate authorization
- Deleting cards before confirming how to add them again
- Testing with another person’s card or account
Prevent the issue from returning
- Carry a physical card or alternative payment method
- Review wallet transfer steps before changing phones
