What is NFC in Xiaomi Note 10 and why you need it
The NFC (Near Field Communication) module in the Xiaomi Redmi Note 10 smartphone allows you to exchange data over short distances - up to 10 cm This technology is the basis of contactless payments (Google Pay, SberPay), fast file transfer between devices, tag readers and even manage smart devices. Despite the apparent simplicity, many users face difficulties when first turning on NFC - especially if you have not previously used this feature.

- π³ Contactless payments via Google Pay, Mi Pay or banking applications (SberBank, Tinkoff, etc.)
- π± Fast transfer of contacts, photos or links to other smartphones NFC (via Android Beam)
- π·οΈ Reading tags to automate tasks (for example, turning on Wi-Fi when touching a tag on your desktop)
- π Emulation of access cards, transport tickets or smart lock keys

Methods of verification:
- Look for the specifications on the box or in the documentation, look for the words "NFC: Yes" or the pictogram of contactless communication.
- Use the CPU-Z app: Download the app from Google Play. Go to the Sensors tab. Check if there's an NFC item in the sensor list.
