Where NFC is in Xiaomi: Location, Verification and Setup

Xiaomi smartphone owners often face the challenge of finding an NFC module immediately after buying a device, which has become the standard for convenient payment, fast pairing of gadgets and transferring files. However, the situation in the model range of the manufacturer from China is ambiguous: not all devices have the module physically, which causes confusion among users.

Finding the answer to the question of where in Xiaomi NFC, begins with the understanding that Near Field Communication is not a software feature that can be enabled with an update, it is a physical chip that is built into the motherboard or placed separately inside the case. If the manufacturer has not put it into the design of a particular model, no manipulation of the settings will make it work, which is why the first step should always be to check the specifications of your device.

In this article, we will discuss in detail how to determine the presence of a module in your smartphone, where it is located structurally and how to properly activate the feature for use in Google Pay or Mi Pay. We will also look at the typical problems when the indicator is there, but the payment does not pass, and how to solve them. Understanding these nuances will save you time and nerves when setting up the gadget.

Design features of the module location

The physical location of the NFC antenna in Xiaomi smartphones depends on the year of release and the price segment of the model. In most modern flagships and mid-range devices, the antenna is integrated directly into or immediately behind the main camera unit. This is due to the fact that the back cover in these areas is often made of plastic or glass, which do not shield the signal, unlike metal.

In older models or budget series, such as some versions of Redmi, the antenna module could be placed under the battery (if it is removable) or be combined with a wireless charging unit. In models with a non-removable battery, the antenna is almost always located at the top of the case, closer to the left or right corner. Accurate knowledge of the location is useful not only for curiosity, but also for the correct attachment of the phone to the payment terminal or smart home label.

It is worth noting that the thickness of the case and materials affect the efficiency of work. Xiaomi engineers tend to place the antenna so that it does not overlap with the palm of the palm in a standard grip. However, in some cases, such as using thick protective covers with metal inserts, the range can be significantly reduced, which creates the illusion of a malfunction.

Use thin covers without metal plates on the back cover to ensure a stable NFC signal when paying.

Checking for NFC in MIUI settings

The fastest and most reliable way to know if your Xiaomi has a communication module is to check system settings. MIUI or HyperOS interface hides the option of enabling NFC if the relevant hardware is missing. If you can't find the switch, chances are the chip in the device is not installed.

To check, do the following: lower the notification curtain and look for the NFC icon. If it's not available in the quick access, go to the settings menu. The path may vary slightly depending on the firmware version, but the logic remains the same for all devices of the brand.

  • πŸ“± Open Settings and use a keyword search "NFC".
  • πŸ” Go to Connect and Sharing (or β€œMore” in older versions).
  • βš™οΈ Find a point. NFC Check if the switch is active.

If the Connect and Sharing menu doesn’t have an NFC partition and the settings search doesn’t work, it’s a clear sign that there’s no module. In some cases, especially on global firmware, the item may be hidden deeper, such as in Wireless. It’s important not to confuse this feature with Infrared Port, which is used to manage household appliances and is present in many Xiaomi models even without NFC.

Using the Engineering Menu for Diagnostics

To get a deeper look at the hardware, you can use Xiaomi's engineering menu, which allows you to see a list of all the sensors and modules that the system has detected, even if they are software-enabled, especially for re-enabled devices or smartphones purchased on the secondary market.

To get into the test menu, open the Phone app and dial ##6484##. The screen will show a list of CIT tests. In this list, you need to find an item related to NFC. It is usually called or labeled "NFC Test".

1. Launch the Phone app.




2. Dial ##6484##.




3. Find it on the NFC list.




4. Press "Start Test" to check the reaction of the antenna.

When you run the test, the system will ask you to hold a card or tag to the back cover, and if the phone vibrates or makes a sound, and the success message appears on the screen, then the hardware is good, and if the NFC point is not on the CIT test list, this confirms that the motherboard does not have a corresponding controller.

⚠️ Warning: Do not change the settings in other sections of the engineering menu unless you are sure of your actions.This may lead to improper operation of radio modules or loss of warranty.

In the Xiaomi, Redmi and POCO range, the availability of the module often depends on the regional version. Global versions (Global) almost always come with NFC, while Chinese versions (CN) of some budget holders may lose this feature. Below is a table of popular series and the status of support for the technology.

Series of devicesPresence of NFCNote
Xiaomi Mi / Digital SeriesThere's everyone.Flagship standard
Xiaomi Redmi Note (Pro/Pro+)There is.Middle and upper segment
POCO F seriesThere is.Gaming flagships
Redmi (budget)Partially.Depends on the year of issue.
POCO M / C seriesRarely.Ultra-budget segment

It is important to consider that in the entry-level Redmi series (e.g. Redmi 9A, 10A), the module is often absent to reduce the cost. At the same time, the Redmi Note series traditionally receives a full set of features, including NFC. When buying a used device, always check the box: the presence of the NFC logo on the back of the package is a sure sign.

Why do Chinese versions often lack NFC?
Manufacturers often save on the module NFC Chinese market is dominated by its own payment systems (WeChat, Alipay) operating through the Chinese market. QR-codes, not chips.

Setting up and using for payment

Once you have made sure that the module is available and activated, you need to set your priorities correctly. In modern Xiaomi smartphones, Google Pay (or its analogues, such as Mir Pay) is most often responsible for communicating with payment systems, so this service should be chosen by default.

Go to the NFC menu in the settings and find the default payment or contactless payments option. Here you need to select the application that will run when you bring your phone to the terminal. If you have a card installed in a Russian bank, you will most likely need Mir Pay or an application of a particular bank.

  • πŸ’³ Make sure that in the settings NFC The option "Allow payment when the screen is off" is included".
  • πŸ”’ Check if the antivirus or security system blocks access to the communication module.
  • πŸ“² Add the card to the selected payment application following the instructions on the screen.

Sometimes the phone is read by the terminal, but the payment doesn't go through, so try to change the position of the device, bring the top of the back cover to the terminal, where the camera is located, and remove the case if it's too thick.

Frequent problems and their solution

Users may experience a situation where NFC in Xiaomi stops working suddenly, most often due to a software failure or application conflict, the first thing to do is to reboot the device, which clears the temporary buffer of the radio module and restarts the system services.

If the reboot didn’t work, check to see if the flight or power saving mode is on.Ultra Battery Saver mode often disables background processes and communication modules to save charge, which blocks NFC. It’s also worth making sure the date and time on the device are set correctly, as this is critical for payment system security protocols.

⚠️ Note: If after resetting the settings to the factory (Hard Reset) NFC not appearing in the menu, this confirms the hardware absence of the module or its physical breakdown.

In rare cases, the problem lies in the update of the firmware. New versions of MIUI may contain bugs that block the operation of certain modules, in which case waiting for a patch or, for experienced users, a rollback to a previous stable version of the software helps.

90% of NFC problems are solved by restarting the phone or re-associating the card in the payment app.

Alternative uses of technology

In addition to payment, the NFC module in Xiaomi can be used to automate tasks and quickly pair. With special applications such as NFC Tools, you can record various commands on tags, and by holding the phone to such a tag, the smartphone can automatically turn on Wi-Fi, start the navigator or set an alarm.

It's also convenient for fast communication of contacts and photos between Android devices via the Android Beam feature (or its modern counterparts), and just hold two phones to each other with the back walls, and the system will suggest transferring data, which is faster and more reliable than searching via Bluetooth.

Xiaomi smart home owners will appreciate the ability to pair new devices quickly. Many Mijia lamps, outlets and sensors support phone touch connectivity, eliminating the need to manually enter Wi-Fi passwords when adding a gadget to the ecosystem.

Can I install an NFC module externally?
There are special ones. SIM-card-holder NFC and external antennas connected through the headphone connector or USB. However, in modern Xiaomi smartphones without an embedded chip, these methods work extremely unstable or do not work at all due to the lack of appropriate drivers in the core of the system.
Does NFC affect battery discharge?
In active standby mode, the module consumes minimal energy; significant discharge occurs only when reading or writing data; keeping the NFC on is always safe for the smartphone to be autonomous.
Why can't the terminal see the NFC phone?
The reasons may be in the dead battery (the discharged battery mode blocks the module), the wrong position of the phone, a thick case or the lack of card tokenization in the bank application.
