The Xiaomi Redmi Note 8T is one of the few budget smartphones of 2019 to receive the NFC (Near Field Communication) module, which allows you to use the device for contactless payments, fast file transfers and even automate tasks through tags. However, many owners still do not know how to properly activate and configure NFC on their model.
In this article, we will not only discuss the basic steps of switching on the module, but also the nuances of its operation on MIUI versions, compatibility with payment systems (including Google Pay and Mi Pay), as well as common errors that interfere with stable operation, and we will focus on security issues, such as why NFC can suddenly turn off and how to avoid it.
If you've never used contactless technology or have trouble configuring on other devices, this guide will help you understand all the details. NFC snippet-based 8T (including global and Chinese versions not found in the standard instructions.
What is NFC and why is it needed on Xiaomi Redmi Note 8T?
Near Field Communication (NFC) technology allows data to be exchanged between devices up to 10 cm without an internet connection. In the Redmi Note 8T, the NFC module is built into the upper part of the case (near the camera) and supports three main modes of operation:
- π³ Card emulation β for contactless payments via Google Pay, Mi Pay or banking applications (SberBank Online, Tinkoff, etc.).
- π± Regime. P2P β transferring files, contacts or links between smartphones (similar to Android Beam, but faster).
- π·οΈ Reading/Writing Labels β Interaction with NFC-chips in smart devices, transport cards or advertising stickers.
In practice, most users use NFC for payments, but the Redmi Note 8T supports more advanced scenarios, such as automating actions through the Trigger app (turning on Wi-Fi when touching a label on the desktop) or a fast pair with Xiaomi Mi Smart Speaker speakers.
Itβs important to understand that NFC only works when the screen is on (unlike the flagship models, which support the background mode), which is a limitation due to hardware optimization and the version of the NXP PN547 chip installed in the device.
