About NFC
Your device allows you to read near field communication (NFC) tags that contain information
about products. You can also use this feature to make payments and buy tickets for
transportation or events after downloading the required apps.
The battery contains a built-in NFC antenna. Handle the battery carefully to avoid
damaging the NFC antenna.
Using the NFC feature
Use the NFC feature to send images or contacts to other devices, and read product
information from NFC tags. If you insert a SIM or USIM card that has a payment feature, you
can use the device to make payments conveniently.
On the Apps screen, tap Settings
→ NFC, and then tap the NFC switch to activate it.
Alternatively, open the quick setting panel and tap NFC to activate it.
Place the NFC antenna area on the back of your device near an NFC tag. The information from
the tag appears.
Ensure that the device’s screen is unlocked. Otherwise, the device will not read NFC
tags or receive data.
