Smartphone owners often look for a way to quickly pay for purchases or exchange contacts, but not everyone knows where to turn on NFC on the Android Xiaomi Redmi 9. This feature turns your gadget into a universal tool for contactless payments and instant data synchronization. Owners of budget models sometimes mistakenly believe that their device lacks the necessary module, but this is not always the case.
In this article, we will discuss in detail the algorithm for activating the wireless interface, as well as the typical problems faced by Redmi 9 users. You will learn how to check for a chip in your particular modification and what to do if standard methods do not work.
Check for NFC Module in Redmi 9
Before looking for a setup, make sure your particular smartphone model is equipped with the right hardware. Xiaomi often releases different versions of the same device for different markets, and the configuration may differ significantly. In some regions, budget versions are deprived of the module of short-term contactless communication in order to reduce the final cost.
The easiest way to check for hardware is to look at the back cover of the device. If the case, usually at the top of the camera or logo, is marked with the designation "NFC", then the module is exactly present. The absence of a sticker does not always mean no function, but is the first signal for a deeper check through software.
You can also use a system search for settings. Type the word in the desktop search bar or menu"NFC". If the phone responds and suggests switching, it means that the software is available. If it's empty, it's worth checking the specifications of your model. IMEI-code on the official website.
⚠️ When buying a smartphone from hand or in unverified stores, always check for a chip, as the visual case of the global and Chinese versions may be identical, but the functionality will differ.
- 🔍 Check the back cover for the presence of a logo.
- 📱 Use search by phone settings.
- 🌐 Check the model by IMEI official website.
- 📦 Check the original packaging and specifications.
It should be noted that the absence of a physical sticker on the case is not a guarantee of the absence of a module, especially if the previous owner removed the protective film. However, having a logo is a guarantee of support for the technology. Owners of Redmi 9 should be careful, since this is a budget segment where manufacturers often save on components.
Standard activation path through settings
If you're convinced that the module is there, the next step is to software activate it. In the MIUI shell that's installed on Xiaomi, the path to the desired switch can vary slightly depending on the firmware version, and most often users find what they want in the basic system settings section.
To access the menu, you need to unlock the screen and find the Settings icon. Next, you need to scroll down to Connect and Share or Additional Features. This is where you focus on managing all wireless interfaces, including Bluetooth and NFC.
In the menu that opens, you'll see a slider that can be turned off by default. Put it back to the active position. The system can request confirmation of action or alert you to battery consumption, although the power consumption in standby mode is minimal. After turning on at the top of the screen, in the status bar, the corresponding icon should appear.
☑️ Activation of the module
Sometimes the path may look different, for example: Settings → More. → NFC. If you don't see an item in the main menu, use the built-in Settings Search by entering the acronym for technology. This is the fastest way to get to the desired menu, bypassing long sections searches.
Use of notification curtain for quick access
For those who plan to use contactless payments regularly, it's much more convenient to have quick access to the switch, and Android has a curtain or control center that you can put on the label, so you don't have to go through the deep settings menu every time.
To add a button, swipe from the top edge of the screen down to open the notification bar. Swipe again or click on the edit icon (usually a pencil or three dots) to go into widget control mode. In the list of available elements, find "NFC" and drag it to the active zone.
Now, you need just one touch to turn the module on or off, which is especially useful when you need to quickly pay for a purchase at the checkout or, conversely, turn off the feature to save battery power at a critical moment. The usability of the interface increases significantly.
💡
Add the NFC widget to the notification curtain for instant access – this will save you time when paying in the store and save you from unnecessary transitions to the settings menu.
Remember that even if you have a widget in the curtain, the module itself must be supported by the hardware of the phone. If nothing happens after adding a shortcut and activating it, it is likely that your version of Redmi 9 has no physical chip, in which case the software methods will not help.
Google Pay and other payment systems
The main reason users are looking for where to turn on NFC on Xiaomi Redmi 9 is the ability to pay for purchases with your phone. To work this feature, one plug-in is not enough: you need to set up a payment application and link a bank card. In most regions, the standard is Google Pay.
The setup process begins with the installation or update of the Google Pay app (or its analogue, depending on the region and the sanctions), after launching the application, you need to log into your Google account, the system automatically determines the presence of an active communication module and prompts you to add a payment means.
To add a card, you can use your smartphone camera to read data or enter information manually. The bank will send a verification code via SMS to confirm ownership of the card. Once successful verification, the phone will be ready to pay at any terminals that support contactless technology.
| Parameter | Description | Importance |
|---|---|---|
| Annex | Google Pay / Mir Pay | Tall. |
| Internet | Required for tokenization | Medium |
| Lockdown | Pin code or print | Critical |
| Module | Must be active. | Critical |
It is important to ensure that the device is protected, and the payment system must have a screen lock: a pin code, a pattern lock or biometric protection, without which the security of your financial assets cannot be guaranteed, and the application will not work.
What is tokenization?
Reading and transmitting mode
The technology isn’t just about payment. Your Redmi 9 can read tags, exchange contacts, and pair with accessories. This often requires you to activate additional modes of operation in the module’s settings, such as Android Beam (although it’s replaced with Nearby Share in newer versions of Android) or read mode.
You can find "Read/Write Mode" or "Android Beam" in the NFC settings menu. If you plan to use your phone to read electronic tags, such as for a smart home or get information from posters, make sure that this mode is on. Without it, the phone will only respond to payment terminals.
To transfer files or contacts between two phones, both devices must have an activated module and an unlocked screen. The transfer process is initiated by simply touching the devices to each other with the back panels. The data transfer speed in this mode is slow, so the method is suitable for small amounts of information.
- 📲 Exchange of contacts through touch.
- 🏠 Reading the tags of a smart home.
- 🎧 Fast pairing with headphones.
- 💳 Emulation of access cards (requires root).
It's worth mentioning that it's often not enough to emulate Android access cards (intercom, office pass) with standard Android tools, which usually requires superuser rights and special applications, because bank cards are protected from chip-level copying, but simple tags are easily readable.
⚠️ Warning: When trying to copy the intercom key, make sure that the frequency of your tag (usually 13.56 MHz) is supported by the phone. Old-style (125 kHz) keys are not readable by smartphones.
Diagnostics and problem-solving
Even if you've followed all the instructions, there can be situations where the function doesn't work correctly, often because of software failure or application conflict, and the first thing you need to do is reboot the device, which is a classic method that eliminates a lot of temporary errors in the operating system.
If the reboot didn't work, check to see if the module is blocked by an installed antivirus or energy-saving app. Aggressive battery saving settings can force background processes associated with wireless interfaces to shut down. Add the payment app to the exclusion list.
It’s also worth checking for system updates. In Settings → About Phone → The MIUI version can run update checks. Xiaomi engineers regularly release patches that fix bugs in the communication modules. An outdated firmware version may contain bugs that interfere with proper operation.
In rare cases, network settings may need to be reset.This action will return Bluetooth, Wi-Fi and mobile internet settings to factory values, but will not affect your personal files.The path to reset is usually in Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
Influence of covers and accessories
And there are physical factors, too. Some cases, especially those with metal backing, magnetic fasteners, or walls that are too thick, can shield the signal. The antenna in Redmi 9 is located at the top of the body, and any obstacle in that area can disrupt communication.
If you notice that the payment terminal has stopped responding to the phone in the case, try removing the protection and repeat the operation, and the problem can be created by glued metal rings-holders (pop sockets) or magnetic plates for car mounts if they close the area of the antenna.
The ideal solution is silicone, plastic or leather cases without metal inserts, which provide the necessary protection of the case without affecting the signal quality. If you use a magnetic case, make sure that the magnets are not located in the area of the camera and logo.
💡
Metal elements in cases and magnetic holders are the most common physical cause of NFC failure, even if the phone's settings are correct.
In conclusion, activating and configuring the wireless interface on Xiaomi Redmi 9 is a simple process, but requires attention to detail. By making sure that the module is available, setting the system correctly and eliminating physical interference, you will have a convenient tool for everyday life.
