How to Connect and Configure NFC on Xiaomi Redmi Note 10S: The Complete Guide to 2026

What is NFC in the Redmi Note 10S and why is it necessary?

NFC (Near Field Communication) technology in the Xiaomi Redmi Note 10S opens up opportunities for contactless payments, fast data exchange and interaction with smart devices. This chip is built into the top of the smartphone body and operates at 13.56 MHz, which allows you to exchange information at a distance of up to 10 cm. Unlike Bluetooth, NFC does not require pre-pairing devices – just simply bring them together.

The main use cases for NFC on the Redmi Note 10S include:

• 💳 Contactless payments via Google Pay, Mi Pay or banking applications (SberBank Online, Tinkoff, etc.)
• 🔄 Fast file transfer between smartphones (Android Beam replaced by Fast Share in new versions) MIUI)
• 🏠 Smart home management: Connection NFC-tags for automation (lights on, scripts running)
• 🚇 Subway and public transport (in cities with technology support)

2. Open the file (photo, document) and click "Share".
3. Select "Fast Share" (or "Android Beam" if you use old firmware).
4. Bring the smartphones back to each other.
