How to use NFC on Xiaomi Redmi Note 8 T: Full Guide

Owners of the popular Redmi Note 8 T smartphone often wonder how to activate and properly use the built-in wireless module.

Understanding the principles of this chip will allow you to turn your smartphone into a universal digital wallet and a tool for interacting with a smart home.

To start with, not all device modifications are equipped with this module, but the Redmi Note 8 T model belongs to the lucky list of gadgets where this feature is present out of the box. The key feature of the Note 8 T model is the presence of a full-fledged NFC chip, which is supported software in all official global firmware MIUI. This distinguishes this device from some other budget solutions of the brand, where hardware may be absent.

Next, we’ll take a look at activation algorithms, security profile settings, and how to use your smartphone to pay for in-store purchases. You’ll learn how to avoid common errors when pairing with terminals and what applications are needed to make the system work properly. The device’s readiness depends not only on the presence of a chip, but also on the correct software configuration.

Location of the module and verification of its availability

The first step before setting up should be to physically identify the location of the antenna. In the design of the Xiaomi Redmi Note 8 T, the communication module is integrated into the top of the back cover, directly above the main camera unit. This area must be brought to the terminal reader or other device for successful connection. The distance should be minimal, usually no more than 2-3 centimeters.

To make sure the software "sees" the hardware, go to the settings menu. Open Settings, then select Connect and Sharing (or just Additional in older versions of MIUI). There you will find NFC. If the switch is active and responsive to clicks, and the contactless payment menu appears in the options list, then the module is good.

There is a quick way to diagnose through an engineering menu or special test codes, but for the average user, it is enough to check the system response in a standard interface. Sometimes after a drop or replacement of the housing, the contact of the antenna plume may be disrupted, which will lead to the disappearance of the item in the menu, in which case the software methods will not help, you will need a diagnosis in the service center.

This is the parameter responsible for emulating a bank card. If the Security Item Location menu has the value "SIM Wallet", payment systems may not work correctly, so it is recommended to manually set the option Payment Application or HCE Wallet.
