Modern smartphones have long ceased to be just devices for calls, becoming universal tools for everyday life. Xiaomi Redmi Note 8 Pro, released in 2019, became a real bestseller thanks to the excellent value for money, as well as the presence of the NFC module. This technology allows you to use the gadget as a bank card, travel card or smart home key, greatly simplifying interaction with the world around you.
However, many users have difficulty in initial setup or find that the contactless payment function suddenly stopped working. Often the problem is not hardware failure, but software limitations or incorrect system settings. MIUI. In this article, we will discuss all aspects of the work in detail. NFC-chip on your device, consider activation methods and methods for solving common errors.
It is important to understand that the correct operation of the module depends on many factors: firmware version, usage region and security settings. We have prepared a comprehensive guide to help you return the functionality of contactless payments and data transfer. Follow the instructions carefully to avoid typical errors and configure the device as efficiently as possible.
Search and activate NFC module in MIUI
The first step should always be to check the basic operating system settings, and in the MIUI shell, wireless interface management is put into a separate menu that can be accessed in several ways, and the fastest method is to use the notification panel, where the corresponding switch is often located.
If you don't have the right icon on the lock screen or notification curtain, you'll need to go to the main settings menu, and you'll need to find the connection and wireless section, and that's where the basic interactions between your Redmi Note 8 Pro and external devices are hidden.
Inside the settings menu, you will need to find Additional Features or Connect and Share, depending on the version of the firmware installed. After you go to this section, you will see a list of available technologies, including an NFC switch. Activate it by moving the slider to the "On" position.
- π± Open the notification curtain and find the icon "NFC" quick-activate.
- βοΈ Go to Settings. β Connection and Sharing for Detailed Configuration.
- π Make sure that the item is displayed in the list of available features NFC.
- π After turning on, wait for the corresponding icon to appear in the status bar.
β οΈ Note: If the switch is switched on NFC If the device does not appear in the status bar, try restarting the device. In rare cases, the system requires re-initialization of the drivers to correctly display the status of the module.
Once activated successfully, the system may request confirmation or offer to configure additional services. Donβt ignore these requests as they are necessary for payment systems to function properly. Itβs also worth noting that in some regions, another payment service may be selected by default, which will require manual replacement.
Google Pay and Alternative Payment Systems
Once the module is activated, you need to configure the software for making payments. At the time of the release of the Redmi Note 8 Pro, Google Pay was the main service, but due to changes in the payment services market in Russia, users from Russia had to look for alternative solutions. For global firmware versions, Google Pay (now Google Wallet) remains relevant.
To get started, you need to download the Google Wallet or Mi Pay app from the official Play Market Store. The app will need to add a bank card, following the instructions on the screen. It is important that the card supports contactless payment technology, as usually indicated by the corresponding logo on the plastic media.
In the application settings, select the added card as the default card, and in the phone settings, make sure that the HCE Wallet is selected in the NFC β Security Element section, which is a critical parameter without which payment may not be made.
Path to setup: Settings β Connection and Sharing β NFC β Security Item Location β HCE WalletIf you use a global firmware device outside of restricted countries, the process is automatic, but in some cases, you need to manually link the card through a banking application. Some banks require confirmation of the transaction via SMS or push notification in their proprietary application.
- π³ Download the latest version of the payment application (Google Wallet, Mi Pay, Mir Pay).
- π Check the card verification through SMS-bank-code.
- π² Set the bank application in priority position in the settings NFC.
- β Check the status of the card: it must have the status of "Main" or "By default".
βοΈ Checking readiness for payment
It is worth considering that for work NFC-For security reasons, transactions are not done with the display turned off.In addition, some banking applications require the installation and update of Google Play Services, without which the functionality can be limited.
Solving NFC Definition Problems on Redmi Note 8 Pro
It's not uncommon for users to experience a situation where the function is enabled in the settings, but the payment terminal or other device does not respond to the smartphone. The first reason may be a case. If you use a security case with metal inserts or a magnetic fastener, it can shield the signal. Remove the case and try to make payment again.
The second common problem is a software failure in Google services or the MIUI shell itself, in which case it helps to clean the cache of system applications responsible for NFC.
You also need to check if antivirus or built-in MIUI protection has blocked access to the communication module, and in the security section, you can sometimes find settings that limit the background operation of applications, which can prevent tags from being read or payments.
| Symptoms. | Possible cause | Method of decision |
|---|---|---|
| Terminal's not responding. | Tight case or metal | Remove the cover, bring closer to the reader |
| Payment error | Incorrect Secure Element | Select HCE Wallet in the settings |
| NFC badge goes missing | System or memory failure | Rebooting the device |
| Can't see the mark. | App out of focus | Unlock the screen before serving |
What do you do if nothing helps?
In some cases, the problem may be physical damage to the antenna, especially if the phone has previously been hit or moisture.The antenna module in the Redmi Note 8 Pro is located at the top of the body, closer to the main camera.
Using NFC to Transfer Data and Automation
The technology isnβt just limited to paying for purchases; Xiaomi owners can use NFC to quickly transfer files between devices via Android Beam (on older versions of Android) or Quick Share, and to connect Bluetooth headsets with a simple touch, which greatly speeds up the process of pairing accessories.
A particularly useful function is to work with NFC-You can buy special programmable tags and customize automation scenarios, for example, when you bring your phone to a desktop tag, your smartphone can automatically turn on silent mode and start a note-taking app.
Label programming uses special apps from the Play Market, like NFC Tools. The process of writing is simple: select the action the phone has to perform, and bring the device to a clean label. Data is recorded instantly and stored even without powering the tag.
- π§ Tap your headphones with your phone for instant pairing over Bluetooth.
- π Transfer contacts and small files by touching another Android smartphone.
- π Use tags to create smart home scenarios (lights on, Home mode").
- π Lock your phone or run apps to touch a programmable tag.
β οΈ Note: When recording data on NFC-Make sure you do not erase important business information if you use corporate or transport cards. Record data only on empty tags or copies intended for experimentation.
Automation of processes through NFC-Labels offer a lot of opportunities for productivity, so you can create a tag for a car that includes a navigator and Bluetooth, or a sleep tag that switches the phone to Do Not Disturb".

Tip: Place NFC-You can set it up so that when you touch it, the phone automatically sends out. SMS-A message to your loved ones about your arrival and included Wi-Fi, which will add security and comfort.
The Impact of the Firmware Region on NFC and Mi Pay
One of the most challenging topics for Xiaomi owners is the dependence of functionality on the firmware region. Global versions (Global ROM) usually have a full set of features, but may not support local payment systems in some countries without additional configuration. Chinese versions (CN ROM) are often deprived of Google services out of the box, making setting up NFC for payment in foreign stores extremely difficult.
In Russia and a number of other countries, re-imbroidered devices or region-reversed versions are popular. If your Redmi Note 8 Pro has Chinese firmware installed, the NFC module can only work for reading tags, but not for emulating maps. Full-fledged work often requires flashing to the global version or installing Google services manually.
Check the region of the device can be in the Settings menu β If you see Chinese characters or no Play Market store, you probably have one. CN-In this case, activation of payment functions will require qualified intervention and installation of appropriate software.
It is worth remembering that changing the region in settings (without flashing) does not always activate hidden functions, for example, switching to the region "India" or "Singapore" may open access to Mi Pay in these countries, but does not guarantee the work with cards of other banking systems.
| Type of firmware | Google Pay / Wallet | Regional restrictions | |
|---|---|---|---|
| Global (Global) | Supported | Depends on the region. | Minimum |
| China (Chinese) | Installation required | Only maps of China | High (no Google) |
| EEA (Europe) | Supported | Limited. | Strict GDPR regulations |
| Russia (Russian) | Limited. | Support for Mir Pay | Specific to the Russian Federation |

The type of firmware determines the payment systems available, and it is critical for users outside China to have a global or European version of the software to work properly with Google Wallet.
Diagnostics of hardware-part and check of serviceability of the chip
If software isn't working, you need to make sure the module is physically fit. The Redmi Note 8 Pro uses built-in engineering code to test the hardware, and you can run NFC testing right from the diagnostics engineering menu without installing third-party apps.
To enter the engineering menu, dial ##6484## in the Phone app. In the test list that opens, find NFC. Run the test and follow the instructions on the screen: you usually need to bring the phone to the reader or tag. If the test is successful, the problem is exactly software. If the test does not start or gives an error, a hardware defect is likely.
You can also use third-party diagnostic applications that read the technical information about the chip, which will show the manufacturer's ID, the firmware version of the chip and its activity status, and the absence of information about the chip in such programs when the switch is on in the system often indicates a plume break or a controller failure.
- π§ Enter the code ##6484## in the Engineering Menu Login Call.
- π‘ Choose a test. NFC and perform a reading check.
- π± Use applications like this "NFC Check for detailed diagnostics.
- π Inspect the upper part of the body for damage and bloating.
β οΈ Warning: Do not attempt to disassemble the phone to check the antenna contacts yourself unless you have experience. careless intervention can damage the plumes of the display or battery, leading to costly repairs.
If a hardware malfunction is confirmed, the only solution is to contact an authorized service center. Replacing the NFC module in the Xiaomi Redmi Note 8 Pro usually does not require replacing the entire motherboard, since the antenna and chip are often taken out on a separate plume or located at the top of the case, which makes repair easier.
