NFC in the phone Xiaomi Redmi 8: is there a module and how to use it

Owners of low-end and mid-range smartphones often face uncertainty about the functionality of their devices, especially when it comes to near-field wireless technologies. NFC in the Xiaomi Redmi 8 phone is exactly the issue that causes the most controversy among users trying to set up contactless payment or automation of tasks. Many confuse the presence of the chip itself in the hardware with the possibility of using it in a particular region, which leads to false conclusions about the inoperability of the gadget.

Understanding the Redmi 8 architecture requires careful study of technical specifications, as this model came about at a time when the Chinese giant began to actively implement communication modules even in affordable lines. However, having an antenna is only half the battle. To work properly, the MIUI shell must be properly configured and the region of use supported payment services. In this article, we will discuss in detail how to check for the module, why it may not work and what workarounds exist for using the technology.

Specifications of the NFC module in Redmi 8

Xiaomi Redmi 8, based on the Qualcomm Snapdragon 439 processor, is technically equipped with an NFC module. This is confirmed by the presence of the appropriate antenna inside the case and support for a firmware communication standard. However, it is important to distinguish between the global version of the device and the versions for the markets, since the manufacturer sometimes software locks or physically excludes the chip depending on the pricing policy of the region.

The main purpose of the module in this model is to provide data transfer over short distances and emulation of cards. Near Field Communication technology in this device operates at 13.56 MHz, which is the standard for the industry. This allows the smartphone to communicate with payment terminals, transport cards and smart tags. It is important to note that the data transfer speed here is low, so the module is not designed to transfer large files, unlike Bluetooth or Wi-Fi Direct.

⚠️ Attention: Availability of logo NFC The back of the box or the settings menu does not always guarantee that the module will work in your country.

System utilities are available to check the chip's technical capability. Unlike flagship models, where chip management is placed on a separate menu, Redmi 8 often integrates settings into general connectivity settings. If there is no switch in the Settings → Connection and Sharing menu, this may indicate a software lock or no chip in a particular board revision.

How to check the availability and performance of NFC

The first thing the user needs to do is do visual and software diagnostics. Often the module is simply turned off by default to save battery power. To activate it, go to the settings menu and find the Connection and Sharing section. This should have a slider on the technology, and if you see this switch, then the hardware of the device is present.

The second step is to use specialized diagnostic applications. NFC Check or NFC Tools can detect the presence of a chip even if the standard menu hides this option. Once you install the application, run a scan. If the application says "NFC is not available", try restarting the device or checking for MIUI updates.

The third way to check is to test the physical test with a tag or payment terminal, hold the phone to a terminal in the store, if you see a message on the screen about a payment attempt or an application request, the module functions correctly, and you can also hold the smartphone to another NFC tag, such as a ticket, to hear the characteristic beep of the system.

• 🔍 Check the Settings section → Connection and Sharing for the Slider.
• 📲 Install a diagnostic app from Google Play Market for deep scanning.
• 🏪 Bring your phone to the payment terminal to check the system's response.
• 🔄 Restart the device if the software methods do not work.

Google Pay and Alternative Services

The main reason users are looking for NFC information in Xiaomi Redmi 8 is to pay for purchases with a smartphone. The standard method involves using Google Pay (now Google Wallet). It requires an unlocked bootloader (not always), an added card in the Google Pay app and an NFC module enabled. It is important that the phone has Google Play services installed, which is relevant for global firmware versions.

However, Chinese firmware owners or users who have been blocked can use alternative solutions, and Mi Pay supports card additions in some regions, but its functionality is severely limited compared to the global standard. There are emulator apps, such as Curve or banking apps with its own payment function (such as Mir Pay for cards of the Russian payment system), which can use the same. NFC-Directly bypassing Google Pay.

The process of setting up a banking application requires care. After installing the bank application, you need to log into your personal account, link the card and allow the use of the security settings. NFC. In some cases, it is necessary to establish PIN-code or enable biometric authorization to confirm transactions, without which payment may not pass even when the module is running.

⚠️ Note: When paying through alternative apps (not Google Pay), the terminal may define the phone as "Unknown Device." This is normal, but the cashier may ask you to try again or enter the card pin.

Work with NFC-tagging and automation

Redmi 8 is not just about paying, but it allows you to use your smartphone to read and write. NFC-tagging, which opens up a lot of possibilities for automation, with applications like this. NFC Tools or Trigger can program your phone to do certain things when you touch a tag, for example, a tag in your car can automatically turn on Bluetooth and start the navigator.

To record data on the label, you need to select the type of action in the application. This can be opening a website, launching an application, sending an SMS or changing the system settings. After selecting the action, the application will prompt you to put a clean or rewritable tag to the back of the smartphone. In Redmi 8, the antenna area is usually located at the top of the case, next to the main camera.

Use cases can be very different: from a “smart alarm clock”, which turns off when you touch the label on the nightstand, to guest Wi-Fi, which is activated when you touch the label on the table.

Compatibility issues and regional constraints

One of the most common problems is the mismatch between the firmware region and the usage region.The global version of MIUI Global usually has no NFC issues, while the Chinese version (MIUI China) may not have the pre-installed Google services required for Google Pay to work.Reflashing the device from the Chinese version to the global version often solves the problem, but requires unlocking the bootloader, which is a difficult procedure for beginners.

There are also restrictions on payment systems: In some countries, services may not work with certain smartphone models due to lack of certification; you can check the status of certification in the Google Pay application in the settings section. If the device is not certified, adding cards will not be possible.

Influence of covers and accessories on the signal

Physical obstacles can significantly reduce the efficiency of the antenna. NFC in the phone works at high frequencies that do not penetrate metal. If you use a case with a metal plate for mounting in the car or a case with a card pocket located on the back cover, this can completely block the signal. In the case of the Redmi 8, where the antenna module is compact, the influence of external factors is especially noticeable.

Thick silicone or leather cases can also weaken the signal, although they do not block it completely. If you notice that you have to apply the phone from an unusual angle or remove the case to pay, the problem is precisely in the accessory. It is recommended to use cases without metal inserts in the area of the module (the upper part of the back cover).

💡

If you carry your phone with your keys or metal objects in one pocket, the metal can shield the signal. Try to keep the antenna area free of foreign objects when paying.
