Modern Xiaomi smartphones have become the standard of reliability and functionality, but the introduction of short-range contactless modules in the budget and mid-range segments has been uneven. Users often face a situation where the payment or data function is stated in the specifications, but finding the physical location of the antenna or activating it in the menu is not an obvious task, due to the fact that the engineering layout of the devices varies from model to model, and the software shells MIUI and HyperOS offer different activation paths.
Understanding where exactly is located NFC-The module is necessary not only for the aesthetic location of the smartphone when paying, but also for the correct use of accessories. For example, when buying a magnetic cover or a holder in a car, it is important to know the area of the antenna so that metal elements do not shield the signal. In this article, we will discuss in detail the physical and software aspects of the technology in Xiaomi devices.
Many people mistakenly believe that the module is always at the top of the body, but in recent generations of Redmi and POCO engineers often shift the antenna closer to the center or even to the bottom edge to optimize the operation of other wireless interfaces. Let's figure out how to choose the right position of the device and configure it for smooth operation.
Physical location of the NFC antenna in the housing
Determining the exact location of the NFC antenna without opening the smartphone is difficult, since manufacturers rarely mark this area on the case. However, empirically it was found that in most flagship models of the Xiaomi and Mi series, the module is integrated into the main camera unit or located directly under the brand logo on the rear panel, which allows you to use the smartphone as a key fob, attaching it to the top of the reader.
In low-end devices such as the Redmi Note series, the design may differ: here the antenna module is often shifted to the center of the housing or is located in the upper third, but does not always coincide with the geometric center. The location of the element depends on the internal architecture of the board and the neighborhood of the battery, which can interfere with improper positioning.
- π Top third of the case β a classic location for the flagships of the Xiaomi series 13/14.
- π Central block - often found in models POCO side-scanner.
- π· Camera module area β characteristic of wireless charging devices where antennas are combined.
- π‘οΈ Under the Mi logo - a universal solution for the middle segment.
β οΈ Note: Using thick metal covers or magnetic clasp cases in the antenna area can completely block the signal NFC, making it impossible to pay or read tags.
To accurately define the zone, you can use the NFC Tools app, and when you start writing or reading, drive your smartphone over the active tag, the point where the connection will be established the fastest and from the shortest distance, and point to the center of the antenna module.
Software activation and search in MIUI and HyperOS
Even if the module is physically present, it can be disabled at the software level. MIUI And the new HyperOS, the way to manage this setting is standardized, but it has its own nuances depending on the version of Android. β Connection and sharing β NFC. Here the choice of the main application for payment is carried out.
It is important to note that in some regional versions of firmware (e.g. Global or EEA), menus may be called differently or hidden. If the standard path does not work, use the built-in Settings Search by typing in the βNFCβ query. This is the fastest way to get to the desired menu, bypassing complex system settings structures.
βοΈ Verification of activation NFC
Once activated, the system may request confirmation of use of Google Pay or Mi Pay (depending on the region). Make sure that the Security section does not restrict the use of NFC only for trusted applications if you plan to read arbitrary tags.

For quick activation of NFC, add the switch widget to the notification curtain: clamp the empty space on the desktop, select Widgets, and find the NFC switch.
Comparison of models: where NFC is and where it is not
Not all Xiaomi smartphones are equipped with a short-range communication module. In the pursuit of lower cost, manufacturers often exclude this feature from the budget models of the Redmi A, Redmi C series and some versions of the POCO M. So always check the specifications of a particular model before buying or trying to customize.
Below is a table to help you navigate the availability of the module in popular lines. Please note that having NFC does not guarantee Mi Pay in your region, but allows you to use third-party applications to emulate access cards.
| Series of devices | Presence of NFC | Location of the antenna | Support for Mi Pay |
|---|---|---|---|
| Xiaomi 13/14 Pro | There is. | Upper part / Camera | Depends on the region. |
| Redmi Note 12/13 | In the Pro+ version | Central block | Limited. |
| POCO F5/F6 | There is. | Top third. | No (Google Pay only) |
| Redmi 12C / 13C | No. | β | β |
The absence of a module in the specification often indicates the use of a simplified motherboard. In such cases, it is not possible to programmatically activate the feature, and any applications promising to βenable NFC softwareβ are fraudulent.
Contactless payment and security settings
The main function for which users are looking NFC-In the Xiaomi ecosystem, this process is tied to Google services. In order to work correctly, you need not only to turn on the module, but also to configure the lock screen. PIN-code, pattern lock or biometrics for conducting transactions.
In the NFC settings, be sure to check the Touch and Pay option (or Default Payment). Google Pay or the installed bank app should be selected here. If another application is selected, payment may not pass, and the smartphone will react to the terminal with vibration, but not initiate payment.
- π Set a reliable method of locking the screen (not βSwipe around the screenΒ»).
- π³ Add the card to the bank app or Google Wallet.
- β In the settings NFC Select Google Pay as the default payment method.
- π± When paying, unlock your smartphone, but do not open the bank application.
β οΈ Note: When adding cards to Google Pay, the bank may request additional verification via Google Pay. SMS Make sure you have access to the phone number linked to the card.
Also worth mentioning is the Security Mode feature, which some firmware has an option that requires unlocking the device for each tag readout, which increases data protection but can be annoying with frequent use of office passes.
Using NFC for Smart Home and Automation
In addition to payment, the module NFC In smartphones, Xiaomi is great at automating tasks through the Google Home or Mi Home app. NFC-A tag that, when touched by the phone, will trigger scripts: turn on the light, set an alarm, start the navigator or turn the phone into Do Not Disturb modeΒ».
To implement this function, you need to purchase empty NFC-tags (usually format) NTAG213 or NTAG215). When you record the action on the automation app, you get a physical trigger, for example, a tag by the bed can turn off all the lights in the apartment and put your smartphone on an alarm clock at 7:00.
What are the best brands to buy for Xiaomi?
Xiaomi smart home devices, such as lamps or outlets, often have a quick pairing function via NFC. Just bring the phone to the device (if it supports Mi Connect), and the Wi-Fi settings are copied automatically, eliminating manual password entry.

NFC in Xiaomi is not only payment, but also a powerful tool for automating household scenarios, which turns a smartphone into a universal home control console.
Diagnostics and solution of problems with the module
If you're sure of a module, but the smartphone stopped responding to terminals or tags, there may have been a software failure or physical damage to the antenna. The first step should always be to restart the device. If that doesn't work, check if the module in the system has switched off after the firmware update.
Application conflict is a common problem: If you have multiple NFC programs installed (e.g., card emulators and banking applications), the system may βloseβ which application to run, in which case cleaning the NFC service cache in the application menu or resetting network settings will help.
If the phone reacts to the terminal with vibration but the payment does not go through, the problem may be on the bank or terminal side, however, if the phone does not vibrate and does not glow with an indicator when it is brought to the operating terminal, the antenna plume inside the case may have moved away, especially if the device has recently fallen.
