What is NFC in Redmi Note 10 and why is it necessary?
The NFC (Near Field Communication) module in the Xiaomi Redmi Note 10 is not just a contactless payment technology; it is a versatile tool that turns your smartphone into an electronic key, a fast data transfer tool, and even a smart home automation device.

- 💳 Contactless payments via Google Pay, Mi Pay or banking applications (SberBank, Tinkoff, etc.)
- 🔑 Emulation of cards: office passes, transport cards (for example, "Troika" in Moscow), keys to intercoms
- 📱 Fast file transfer between devices (Android Beam replaced with Fast Share in new versions) MIUI)
- 🏠 Smart home: management NFC-tags to start scripts (turn on the light, start the coffee maker, etc.)
