Owning a modern smartphone involves the use of many hidden features that greatly simplify everyday life, and one of the most popular technologies is Near Field Communication. Users of Xiaomi, Redmi and POCO devices often wonder how to properly activate this module to pay for purchases in one touch or share files. Despite the apparent simplicity, there are nuances in the shell of MIUI or HyperOS that can confuse the inexperienced owner of the gadget.
In this article, we will take a look at all the steps of the setup, from finding a switch in the menu to solving problems with banking applications, how the chip sometimes malfunctions and how to get it to interact with payment terminals.
Verification of the module and its activation
Before you start setting up, you need to make sure that your particular device is physically present antenna. Not all budget Xiaomi models are equipped with a near-field communication module, so the first step should always be to check the specification of your device. If technically possible, move to the software part.
The fastest way to activate the feature is to use the notification curtain. Swipe from the top edge of the screen down to open the Quick Access panel, and find an icon that says NFC. If it's not in the front row, tap on a pencil or edit button to add the icon to the active menu, then just tap it to turn it on.
The alternative is through system settings, which is especially true if you want to adjust the settings in more detail. Go to Settings, then select Connect and Sharing (older versions of MIUI might have called "More" or "More"), and here you will see a switch that needs to be switched to active position.
- 📱 Quick activation through the notification control panel.
- ⚙️ Deep setup via the “Connection and Sharing” menu».
- 🔍 Search function through the search bar in the on-demand settings «NFC».
Once enabled, the system can request confirmation or suggest selecting the default payment processing app, a normal reaction of the Android operating system that requires prioritizing the service.
Configure Pay elements and contactless payment
The main reason users are looking for information about setting up NFC on Redmi and Xiaomi is the ability to pay for purchases with a smartphone.In an environment where standard Google Pay services may be limited in some regions, it is important to properly configure alternative methods or restore existing ones.
To make payments work properly, you need to activate HCE (Host Card Emulation) in your security settings. Go to the NFC menu and make sure that the "Use HCE" option is on, and this protocol allows you to emulate a bank card inside your phone's chip.
⚠️ Note: If you use third-party card emulation apps (not official banking apps), make sure they have the necessary access rights and are not blocked by the power saving system. MIUI.
Next, select the default payment element. In the list of available applications, select your bank or service that you plan to use most often. If you add a new card, the system will automatically prompt you to configure it through the appropriate application.
☑️ Checklist for setting up payment
Importantly, some banking apps may require additional setup in the “Security” section of the smartphone itself.Make sure the app has permission to use the communication module and geolocation access if required to confirm transactions.
The location of the antenna and proper use
Many users face a situation where the phone is brought to the terminal, but the payment does not pass. Often the problem lies not in the software failure, but in the wrong positioning of the device relative to the reader. The antenna in Xiaomi and Redmi smartphones can be located in different places depending on the model of the case.
In most modern models with screens without frames, the antenna module is shifted to the top of the rear panel, closer to the camera. However, in older or compact models, it can be located in the center or even in the area of the brand logo.
| Device series | Location of the antenna | Recommended attachment area |
|---|---|---|
| Xiaomi Mi (8, 9, 10) | Top third of the hull | Main cell area |
| Redmi Note (7-12) | centre or top | Central axis, just above the logo |
| POCO (F, X series) | Upper part | Corner near flash |
| Xiaomi 11-14 Series | Top cell block | Directly under the camera module |
When paying, try not to make sudden movements. Hold the phone smoothly, hold it at a distance of 1-2 centimeters from the terminal until there is a vibration or an audible signal. Using a dense case with metal inserts can block the signal, so in such cases it is better to remove the case.
Why does the cover interfere with the NFC?
Data transfer and tagging
Near Field Communication is used not only for finance, but also for fast data exchange between devices. On Xiaomi smartphones, this feature is often integrated with the branded shell, allowing you to transfer contacts, links to sites and small files just by touching the back of another smartphone.
To transfer files between two Android devices, the feature is often called Android Beam (older versions) or simply NFC Sharing. Make sure that Bluetooth is enabled on both devices, as NFC is only used for primary pairing, and the data transfer itself goes over a faster channel.
- 📂 Open a photo or contact that you need to share.
- 📲 Put your smartphones on top of each other with the back panels.
- ✅ Wait for the request to send and confirm the action.
It is also used to read programmable tags, and you can buy special labels, program them to perform actions (for example, turning on Wi-Fi when you touch your phone to a tag on your desk), and use them to automate scripting in the Mi Home app or third-party utilities.
⚠️ Be careful when scanning unknowns NFC-Intruders can encode a link to a phishing site that will open automatically when touched.
Solution: the module is not working or not visible
If you have switched on in your settings, but the terminal in the store is not responding to the phone, or the settings item itself is missing from the menu, you need to conduct a diagnosis. Sometimes the problem lies in the banal software failure of the Android NFC service.
The first thing you should do is try to restart your device, which restarts all system services, including the drivers of the communication module, and if you still have a problem after the restart, check if you have an application that conflicts with system security features.
💡
If the NFC is gone after a system update, try clearing the Settings and Security app cache, which often helps to return disappeared menu items without losing personal data.
If the phone fell or was exposed to moisture, the antenna plume inside the case could have moved away. Checking the integrity of the hardware part is possible through the engineering menu, but for the average user it is safer to contact the service center if the software methods did not help.
Using the Engineering Menu for Diagnostics
For advanced users who want to make sure that the hardware part is working, there is a possibility to check through the Xiaomi engineering menu.
To get there, open the Phone app and enter the code ##6484##. From the menu that opens, select the item associated with NFC (usually called or located in the Connectivity section), run the test and follow the instructions on the screen, bringing the phone to the reader.
##6484##If the test shows an error or the module is not detected even in the diagnostic mode, it is likely a physical malfunction, in which case the software settings, resetting to the factory plants or flashing will not work, and a replacement of the component will be required.
💡
If the NFC engineering test fails, the problem is hardware in nature - the software configuration is powerless here, repairs are needed.
