Modern smartphones have long ceased to be just devices for calls, becoming universal tools for everyday life, where the key role is played by the short-range module. For owners of budget but reliable devices from Xiaomi, such as the Redmi 7 model, the question of setting up contactless payment and fast data exchange remains relevant. Owners often look for a way to turn on NFC on the Xiaomi Redmi 7 to use the smartphone as an electronic card or wallet.
NFC (Near Field Communication) provides short-distance communication, allowing you to transfer files, read tags and pay for purchases with a single touch. However, in the MIUI shell, which is installed on Redmi 7 by default, managing this module can have its own characteristics that differ from pure Android. Understanding the principles of this interface will help you avoid unnecessary calls to the service center.
In this article, we will take a look at all aspects of how technology works on your device, look at standard activation methods, payment settings, and possible reasons why the feature may not work even if it is stated in the specifications.
Check the availability of NFC module in Redmi 7
Before you start settings, you need to make sure that your particular device is equipped with the necessary hardware. The Redmi 7 model was released in various versions for different markets, and the availability of a communication chip depends on the regional version of the firmware. In some cases, users try to activate a feature that is physically not in the device, which leads to confusion and false conclusions about the malfunction.
The easiest way to check for a module is to look at the back cover of a smartphone or a box from it. Usually, the Xiaomi or Redmi logo is marked with a characteristic inscription "NFC." If this is not marked, this does not always mean that there is no chip, but is the first signal for a deeper check through the software menu.
- π± Pay attention to the back panel of the device at the top.
- π¦ Check the technical specification on the original packaging.
- π Global versions often have a chip, while Chinese versions donβt.
You should also go to the system settings to see if there is a corresponding menu item. If you don't find an option in any of the sections, chances are that your version of the smartphone has no hardware module, in which case software activation is impossible, and no firmware will add a physical component.
β οΈ Warning: Attempts to install third-party apps from the Play Market store promising "emulation" NFC" These programs only work as readers if the module is there but is turned off, or are a common marketing ploy.
Basic activation through the notification curtain
The fastest way to run a communications module is to use the Quick Access Panel, which is standard for all Android devices, including the MIUI shell version 10 or 11, which is relevant for Redmi 7. You don't have to dig into the depths of the menu, just swipe a few times around the screen.
Unlock your smartphone screen and swipe from the top edge of the display down to open the control center. If you don't see an NFC acronym icon among the shortcuts, try swiping left or pressing the edit button (usually a pencil icon or three dots) to add the missing item to the panel.
βοΈ Verification of activation
Once you click on the icon, it should light up, and the status bar will show the corresponding symbol, which means that the radio module is active and ready to go, and now the smartphone can detect nearby devices and tags.
- π½ Swipe down from the top edge of the screen.
- π Find the icon "NFC" or".
- β Click on it to make it active (colored).
If you plan to use your phone for payments after you turn on, that's not enough, you need to set up security and choose the default payment app, which we'll talk about in the next sections, and just turning on it just starts the radio exchange.
Configure via the MIUI system menu
A deeper setup is available through the main system settings menu, which is preferable if you want to configure the behavior of the module in detail or if there is no shortcut in the curtain. The path to settings may vary slightly depending on the version of MIUI, but the logic remains the same.
Go to Settings, then select Connect and Sharing (or simply "Advanced" in older versions). Here you will find the NFC switch. The same menu often contains the "Tag Positioning" setting, which is important for correct reading.
Hidden settings of the engineer
The important thing is to choose a security element: Google Pay (now Google Wallet) or Mi Pay must work, and in the NFC settings, select Security Element: HCE Wallet. Without this step, payment applications will not be able to access the secure communication channel.
| Parameter | Recommended value | Description |
|---|---|---|
| NFC | Included. | Activation of the radio module |
| Android Beam | Included. | For file transfer (outdated) |
| Security element | HCE Wallet | For payment systems |
| Touch and pay | Always. | Unlocking mode |
After making changes to the Settings menu β Connection & Sharing β NFC, the system may require confirmation of actions. Make sure all items are saved before leaving the settings menu.
Use for contactless payment
The main reason users want to enable NFC on Xiaomi Redmi 7 is the ability to pay for purchases in stores by terminals. To do this, you need to install and configure the Google Pay app (or its current analogue Google Wallet).
First, make sure that your phone has all the necessary security updates and the MIUI system is up to date. Open the payment system app, log in to your Google account and click Add Card. Follow the instructions on the screen by entering card details or scanning it through the camera.
It is important that the right security element is chosen in the NFC settings (as described in the previous section): If you use Mir cards and Russian banks, standard Google Pay may not work due to sanctions, and you will need to install specialized applications such as Mir Pay through alternative app stores.
- π³ Link the card in the application of the bank or payment system.
- π Set the screen lock (PIN-code, pattern lock or print).
- π² When paying, bring the top of the smartphone to the terminal.
If you successfully set up your smartphone will vibrate or sound when you contact the terminal. If payment does not occur, check if the battery is discharged below the minimum level, as some models block NFC at a critically low charge to save energy.
File transfer and work with tags
While the era of transferring large files over Android Beam is slowly fading, giving way to Quick Share, NFC technology is still used to quickly pair devices.On Redmi 7, you can use NFC to instantly connect Bluetooth headsets, speakers or smartwatches.
To transfer files through NFC (If both devices support Android Beam, you need to include this option in the settings menu. NFC. Then just attach the backs of the two smartphones to each other. When you receive a request for transfer, tap the screen and the file will start to be transmitted via Bluetooth or Wi-Fi Direct initiated by the user. NFC-signal.

Use it. NFC-Automation tags: Buy programmable tags and set them up so that when you touch the phone to the tag on the desktop, the βDo Not Disturbβ mode is turned on or the navigator opens.
And NFC is also used to read smart tags, and you can program tags like this to do things like turn on Wi-Fi, start an app, send a message, and that turns your Redmi 7 into a smart home remote control or a personal assistant.
β οΈ Note: When reading unknowns NFC-Be careful of tagging in public places (advertising posters, business cards) and attackers may tag a link to a phishing site. The phone will ask permission to open a link - do not confirm the action unless you are sure of the source.
Diagnostics and problem-solving
If you've done all the steps, but the function doesn't work, it might be a software glitch or an application conflict, often with a simple reboot of a device that resets the radios, turn the phone off completely and turn it back on in 10 seconds.
Check if you have a case with a metal plate or a magnet on the back cover. The metal shields the signal, and the NFC module on the Xiaomi Redmi 7, which is located at the top of the case, just can't "break through" the protection. Take off the case and try again.
Also worth checking is the list of apps that have access to NFC. Go to Settings β Apps β Permissions β NFC. Make sure that payment systems and the necessary Google services are allowed access. If access is denied, the feature will not work.
- π Reset the device to reset temporary errors.
- π΅ Remove the cover, especially if it contains metal or magnets.
- π‘οΈ Check permissions for applications in privacy settings.
In rare cases, the problem may lie in a firmware update that contains bugs. If the problem occurs after the update, wait for the patch or, for power users, consider rolling back the MIUI version.

If the NFC module is no longer detected by the system after falling or getting moisture, it is likely that the antenna plume or the chip itself is damaged, which requires contacting a service center for repair.
