The modern smartphone has long since ceased to be just a device for calling and communicating in instant messengers, becoming a full-fledged digital wallet. Owners of the popular budget model Xiaomi Redmi 8 often wonder how to activate the NFC feature for fast payment in stores. It is a near-contact communication technology that allows you to exchange data between devices from a few centimeters away.
Many users confuse having a logo on the box or in the specifications with the real possibility of making payments, but the software part requires a separate setup. In this article, we will discuss in detail how to check for a chip in your device, activate the module and link a bank card for comfortable use in everyday life.
Before you start setting up, it is important to understand that Redmi 8 was released in different versions for different markets. The global version and model for China can differ in components, so the first step is to accurately determine the specifications of your instance. Only models with the NFC marking in the title or on the box are equipped with the appropriate antenna module.
Checking for NFC Module in Redmi 8
The first and most important step is hardware verification. Not all versions of the Xiaomi Redmi 8 are equipped with a short-range chip, as the manufacturer sometimes saves on components in budget lines. The easiest way to find out the truth is to inspect the original box from the smartphone. On the back of the package, where the main characteristics are indicated, there should be a special NFC logo. If it is not, software activation of the function will be impossible.
If the box is lost, you can use software diagnostics through the settings menu of the MIUI operating system. Go to the settings section and carefully study the available connectivity options. The absence of a switch in the menu often indicates the absence of a hardware part, but sometimes the module is simply hidden or disabled at the firmware level.
To do a deeper look, you can use third-party diagnostic tools that read information about all the sensors in the device, and these apps show a detailed report of what modules the operating system sees, and if there's no mention of the NFC Controller on the sensor list, then there's no physical chip in the phone.
β οΈ Warning: Do not attempt to install third-party drivers or patches from unverified sources if the settings menu is not visible to the module.This can lead to unstable system operation or kernel conflicts, as it is impossible to software create the missing hardware.
There is also an engineering menu available through a special code set in the Phone app, and by typing a command, you will be taken to the testing section where you can run automatic checks on all components, and if you successfully complete the NFC test, you will confirm that the module is functional and has a module.
Activate NFC through the system menu
Once you've made sure that you have a module, you need to activate it correctly. The standard turn on path is in the Settings section, which is available through the gear in the notification curtain or in the main application menu, and here you need to find the connection and wireless networking item.
Depending on the version of the MIUI shell, the path may vary slightly, but the logic remains the same. You'll need to go to Connect and Sharing or Additional Features, and that's where the main switch that triggers the antenna is.
βοΈ Activation of the module
Once the slider is enabled, the system may request confirmation or suggest setting up additional security options. It is important to choose a region of use if the Google Pay app or banking app requires this to work properly to tokenize cards. In some cases, you also need to activate the Android Beam feature to transfer files, although this is not critical for payment.
For quick access to the module management, add the widget to the notification curtain. Swipe from top to bottom to open the control center, find the NFC icon and click on it. If the icon is not in the standard set, click on the edit pencil and drag the desired element to the active panel.
| Parameter | Standard value | Recommended value |
|---|---|---|
| Module status | Off. | Included |
| Mode of work | Reading/Recording | Emulation of HCE map |
| Main annex | Not selected. | Google Pay / Wallet |
| Lock screen | Demand unlocking | Allow payment |
Setting up contactless payment
The process of setting up payment requires a Google account and the bank application installed. Once the module is activated in the smartphone settings, the system will prompt you to choose the default application for making payments. 90% of the time it will be Google Pay (or Google Wallet in new versions), as it provides the highest level of security transactions.
Go to the NFC settings and find Pay without contact or Touch for payment, and here you will see a list of all the apps that the module can use, and select the one you want to bring your phone to the terminal, so that the system automatically starts it.
Then you need to add a bank card. Open the payment system app, click Add Card and follow the instructions on the screen. You will need to take a picture of the card or enter the data manually, and then confirm the account ownership through the account. SMS-bank-call.

If the terminal doesn't read the map the first time, try changing the angle of the smartphone or the speed of the conduction. The antenna in Redmi 8 is located at the top of the case, so you need to attach this segment.
Importantly, to make the payment work, the smartphone screen must be unlocked, but you don't have to manually run the application, just turn on the screen and bring the device to the terminal, and the system will know that the payment is being made, and use the stored token.
β οΈ Note: When linking the card, make sure that the date and time on the smartphone are set automatically.Synchronizing the time for more than 5 minutes can lead to an error in card tokenization or terminal failure to conduct an operation.
Use of alternative payment systems
Apart from standard solutions from Google, owners of Xiaomi Redmi 8 can use payment systems from specific banks or transport cards. Many banking applications, such as Sberbank Online, Tinkoff or Mir Pay (depending on the region and current restrictions), have their own payment modules.
To work, these applications require NFC to select the Host Controller (HCE) card emulation mode, which allows a smartphone to pretend to be a plastic card for a reader, and without HCE enabled, most banking applications will not be able to conduct a transaction.
Some users prefer to use virtual maps of transport systems, which requires downloading the carrier's app, downloading the balance, and selecting the card as the main one in the module settings, which allows you to pay for a subway or bus fare with a single touch.
In the rare cases where standard methods do not work due to regional constraints, users turn to certificate installation, however, this method requires in-depth knowledge and may not be safe for financial data, so we do not recommend using it unless absolutely necessary.

Solving Typical Problems and Errors
Despite the simplicity of the technology, Redmi 8 users may face a number of challenges: often the module stops seeing maps after updating the firmware or installing βheavyβ themes that conflict with system processes, in which case resetting network settings to factory values helps.
Another common problem is a thick protective case, and if you use a case with metal inserts, a magnetic clasp, or just a very thick silicone, the signal can be blocked. Take off the case and try to make payment again. If the problem is gone, then it was the accessory.
You also need to pay attention to the condition of the module itself, because over time, the antenna can move away from the plume, especially if the smartphone falls, and if the phone stops seeing any cards, even after resetting and flashing, you may need to have physical repairs at the service center.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| Terminal beeps, but no payment | Not selected by default application | Select Google Pay in NFC settings |
| The phone vibrates, but the screen doesn't light up. | Screen's off. | Unlock your phone before paying |
| Bank communication error | No internet or time is lost | Check date and connection |
| The module is off. | System failure or lack of a chip | Resetting settings or checking the box |
β οΈ Warning: If after resetting the settings and checking the case, the module still doesn't work, don't disassemble the phone yourself if you don't have experience. NFC Redmi 8 is integrated into the plume or back cover, and it is easy to damage if you open it neatly.

Most payment problems on Redmi 8 are solved by choosing the right default app in NFC settings and removing the thick case.
