In today’s smartphone world, it’s hard to imagine a device without a short-range contactless communication module. Users of the Xiaomi and Redmi ecosystem often face the need to quickly configure this interface to pay for purchases or share data. However, the standard location of switches in the MIUI or HyperOS shell may not be obvious to a beginner. In this guide, we will discuss in detail all the ways to activate and finesse the technology.
Many owners of budget models mistakenly believe that the function they do not have, although it is simply hidden in the depth of the menu or turned off by default for the sake of saving energy. NFC-The module provides access to contactless payments through banking applications and instant file transfer. Let's figure out where to look for the cherished switch and how to make it work correctly.
Search and activate through the control panel
The fastest way to launch a communication module is to use a notification curtain. Swipe your finger from the top edge of the screen down to unfold the Quick Access panel. Among the many icons, find an icon that says NFC. If you don't see it on the first page, swipe left or press the edit button (usually a pencil or three dots) to add a widget to the main screen of the panel.
After pressing the icon should light up, which indicates the successful activation of the antenna. In some versions of the firmware, a small arrow or an additional menu may appear next to the button, allowing you to select the default application for processing tags, which is especially useful if you have multiple programs installed for emulating cards.
⚠️ Warning: If the phone starts to heat up or discharge quickly after being turned on in the curtain, check if the device is pressed against metal objects or other chip cards.
Sometimes the system can automatically turn off the module to save charge if it is not used for a long time. therefore, with each new payment session, it is worth checking the status of the indicator.
Deep configuration in the system menu
If fast access is not enough, full control of wireless interfaces is through the main settings menu. Go to Settings → Connection and Sharing. This is where all the options for Bluetooth, Wi-Fi and the communication chip we're interested in are concentrated. In older versions of MIUI, this section could be called "Additional" or "More."
Inside the menu, you'll find a switch that duplicates the curtain function, but below you'll find more subtle settings. You can choose the mode of operation: read and write, emulate a card or Android Beam. To work correctly, you need to make sure that you choose the security application MI Pay or a third-party service, if it is supported in your region.
- 📱 Reading mode: allows the smartphone to read information from passive tags, such as smart price tags or advertising stickers.
- 💳 Emulation card: turns your phone into a plastic card, which is necessary for payment in terminals.
- 📡 Android Beam: An outdated but still working protocol for transferring files between two devices when touched.
It is important to note that the choice of security element affects which applications will access the chip. If you plan to use banking services, make sure that the appropriate application or “HCE Wallet” is selected at this point. Incorrect setting of this option is a common reason why the terminal in the store does not see the phone.
Why is the security option missing?
Setup of payment and services Mi Pay
For Xiaomi and Redmi app owners, Mi Pay is the primary contactless payment tool, although availability varies by country. To add a card, you need to open the Security app or a separate Mi Pay app, which is often preinstalled. Follow the instructions on the screen to link your credit card.
The verification process usually takes a couple of minutes and requires confirmation via SMS or a banking application, and once successfully linked, the card becomes tokenized, meaning that the real card data is not transmitted to the terminal, but a unique digital code is used, which ensures a high level of security for your finances.
| Parameter | Description | Status |
|---|---|---|
| Tokenization | Replacing card data with a digital token | Actively. |
| Limit without pin code | Amount not to be unlocked | Depends on the bank. |
| Default application | Payment processing programme | Tune in. |
| Screen protection | Device unlock requirement | Recommended |
Keep in mind that to work, the device screen must be turned on and in some cases unlocked, and security settings allow you to choose whether a pin code or fingerprint scan is required for each transaction, preventing random payment if the phone is just in your pocket next to the terminal.
☑️ Checking readiness for payment
File transfer and work with tags
While payment is a leading technology, it’s also great for sharing data: Android Beam (or its counterparts in newer versions of Android) allows you to transfer contacts, website links and photos by simply touching the back of one phone to the other, and both devices must have Bluetooth and NFC enabled.
In addition to the transmission between phones, the module is actively used to read passive tags, such tags can be pasted at home on the router so that guests do not need to enter a password from Wi-Fi manually, just hold the phone. Also popular are automation scenarios: a tag in the car can automatically turn on Bluetooth and start the navigator.
To write your own data to clean labels, there are special applications from the Google Play store, URL-This turns a smartphone into a universal tool for managing a smart home or organizing a workspace.
⚠️ Note: When writing data to tags, make sure you don't overwrite service information if the tag has already been used before. NDEF.
Diagnostics and verification of module availability
Not all Redmi and Xiaomi models have this module, especially in the budget segment. To know exactly if there is hardware in your device, you can use the engineering menu or third-party utilities. The most reliable way is to install an application like NFC Tools or AIDA64.
When they launch, they will show the status of the technology, and if there's no mention of NFC in the About section or in the specification on the official website, it won't be software-enabled -- there's no antenna, and often, instead of having the NFC logo on the back, they can have an AI logo or a glossy insert.
- 🔍 Visual inspection: presence of a logo NFC on the back cover (not always guaranteed).
- 📲 Applications: Use of utilities for equipment inspection.
- 🌐 Manufacturer's website: checking the full specification by model number.
If there is a module, but it is not defined by the system, the antenna plume inside the housing may have moved away after falling, in which case software methods will not help, you will need to disassemble the device and check the connection of the antenna module to the motherboard.

Use the Testing app (code ##6484##) to check your health. NFC-antennas without installing third-party software. NFC Test and bring the map.
Solving problems and mistakes
A common problem is when the phone stops seeing cards or terminals. This can be caused by a thick protective case, especially if it contains metal elements or magnets. The metal shields the signal and communication is interrupted. Remove the case and try to repeat the operation.
Another cause of failure is application conflict, where if you have multiple programs installed to emulate cards or access keys, the system may "mix up" which application to run when you reach the reader. In the Connection and Sharing settings, force the default application to be selected.
In rare cases, resetting your network settings helps, which will return Bluetooth, Wi-Fi and mobile internet settings to factory values, but will not delete your personal files or contacts.

💡
The stable operation of NFC depends not only on the software settings, but also on the absence of physical obstacles (cases, metal cards) between the antenna and the reader.
Final recommendations on the use of
Short-range technology has become an integral part of the modern Xiaomi smartphone.Precisely configured to forget about carrying a wallet with cards and makes it easier to interact with the digital infrastructure.Regularly check system updates, as manufacturers often improve the stability of the module in new versions of Android.
Use the power of tag automation to make your device more convenient. Don't be afraid to experiment with settings in safe mode, but always keep in mind the basics of digital hygiene. Your smartphone is a powerful tool, and NFC is one of its most useful interfaces.
If none of these methods helped solve the problem and a service center check confirmed that hardware was working, it may be due to regional software restrictions, and users sometimes resort to changing the region in their phone settings or installing global firmware versions, but this requires caution.
