What to do if payments using NFC on the Xiaomi Watch 5 fail?

Question

Accepted Answer

If payments using NFC on the Xiaomi Watch 5 fail, please refer to the following aspects:
1. When using NFC payments on the Xiaomi Watch 5, keep the distance within 0–2 cm. Try to align the back of the watch (the NFC antenna area) directly with the card reader and avoid excessive tilting.
2. Ensure the watch screen is turned on, as NFC payments are not supported when the screen is off.
3. Make sure the watch battery has sufficient charge, as NFC payments are not supported when the battery is critically low.
4. The Xiaomi Watch 5 does not require a mandatory time interval between two NFC payments, so it can theoretically tap consecutively. However, in practice, there will be a 1–2 second “cooldown” or processing time, depending on the device and the payment terminal.
5. If the issue persists, restart the watch and try again.
6. Please contact the local after-sales service if the problem continues after trying the steps above.
