A modern smartphone is hard to imagine without contactless payment or fast file transfer, and the Redmi 9 is no exception to the line of popular devices. However, many users face difficulties when trying to activate this module, since hidden settings often cause confusion among gadget owners. In this article, we will discuss in detail how to enable NFC in the Xiaomi Redmi 9 so that you can enjoy all the benefits of modern technology.
It’s worth noting that hardware doesn’t always guarantee the function out of the box, as software restrictions or regional versions of firmware can block access to menus. In global versions of Redmi 9, the NFC module is often software-enabled and requires additional actions or region change to activate it. We’ll look at all possible scenarios, from standard settings to more sophisticated methods of circumventing system constraints.
Understanding the wireless interface will help you not only pay for in-store purchases, but also sync your smartphone with a smartwatch or read electronic keys. Let's figure out where to look for cherished switches and what to do if the standard path does not lead to the desired result.
Check for NFC Module in Redmi 9
Before you get to the settings, you need to make sure that your instance of the smartphone is physically equipped with the necessary communication module. The fact that the manufacturer produces various modifications of the Redmi 9 for different markets, and in some budget versions the short-range chip may not be at all. Checking the specifications on the box or in official documents is the first step that will save you from unnecessary manipulation of the system.
There are several ways to check for hardware, and the easiest way to look at the back of the device is to look at the back cover: if the NFC logo is on the case, the module is there, and you can also use third-party tools from Google Play that scan system reports and give you accurate information about the available components.
- 📱 Check the back of the smartphone for a logo NFC antennae.
- 🔍 Use the app «NFC Check or analogue scanning system.
- 📦 Examine the technical documentation or box from the device for mention of the chip.
- ⚙️ Try to find a point. NFC In the standard settings menu, even if it is inactive.
If the hardware is present but it is hidden software, it can be fixed, but if the chip is not physically present, no software methods will help, and you will have to use alternative methods of payment or data transfer.
Standard activation via the settings menu
In most cases, when the module is present and the region of the device meets the requirements, the activation is through the standard menu. You need to go to the Settings section, then select the Connection and Sharing (or "More", depending on the version of the MIUI shell), This is where the main wireless interface switches are located.
Find the NFC bar in the list and move the slider to the active position. After that, the system can suggest selecting the default payment application where you should specify Google Pay or Wallet. If the item is not in this menu, try searching by settings by typing the acronym into the search bar.
Sometimes activation requires rebooting the device to apply the changes. Once the notification curtain is turned on, a corresponding icon should appear to signal the module's readiness to work. If the switch is gray or absent, then we move to more complex methods.
☑️ Activation checklist NFC
Activation through region shift
One of the most common reasons for the lack of functionality is the wrong region in smartphone settings. Xiaomi often software restricts NFC in certain countries due to local regulations or certification features. Changing the region to a country where services work freely (for example, Singapore, India or some countries in Europe) can unlock access to the menu.
To do this, go to Settings → Additional → Region. From the list that opens, select the right option, for example, Singapore or Indonesia. After changing the region, the smartphone can restart or simply update the list of available services.
⚠️ Warning: Changes in region may affect some system applications, weather widgets and Mi newsfeed. NFC You can try to return the region, but the function may disappear again.
This method often helps owners of global firmware versions where the module is present but hidden by a software crutch, and if a switch appears in the Connect and Sharing menu after changing the region, then the problem was geographical limitations.
Which regions work most often?
Use of engineering menus and hidden codes
For advanced users, it is possible to activate the module through an engineering menu or special codes, which requires caution, since incorrectly changing the parameters can lead to unstable operation of the radio modules. Enter the dialer code ##6484## to enter the hardware engineering menu.
In the test list, look for the item associated with NFC and check the status of the chip. If it shows that the module is disabled, try changing the value to Enabled. However, in newer versions of MIUI, access to changing these parameters is often closed, and the menu only works in read mode.
Alternatively, use code ##865697654##, which in some versions of the firmware compulsorily includes NFC. Type the combination into the dialer and wait for a pop-up notification of success. If the code failed, then your version of the system does not support this activation method.
| Activation method | Difficulty | Risk of failure | Efficiency |
|---|---|---|---|
| Standard menu | Low. | Absent. | High (if available) |
| Change of region | Low. | Minimum | Medium |
| Engineering codes | Medium | Medium. | Low/Mediocre |
| Root rights | Tall. | High-pitched | Maximum |
Solving problems with Google Pay and Payment
Even after successful activation, Redmi 9 users may find that payment is not going through or the terminal is not seeing the phone. Often the problem lies in the security settings or the default application selection. Make sure that Google Pay (or Wallet) is the primary payment application in the NFC settings.
It is also worth checking if the function is enabled. HCE (Host Card Emulation. Without this, the card emulator won't start. Path to setup: Settings → Connections → NFC → Location of the security (or similar) option: Select "Wallet" HCE».
- 💳 Make sure that the card is added to the payment system application and verified by the bank.
- 🔒 Check if the smartphone screen is unlocked at the time of access to the terminal.
- 📡 Make sure the internet is turned on to tokenize the transaction.
- 📱 Remove the cover if it contains metal elements or magnets.
Sometimes cleaning the cache of the Google Pay app helps. Go to Settings → Apps → Google Pay → Memory → Clear the cache. After that, restart the device and try to make the payment again.
💡
If the terminal doesn’t read the card the first time, try slowly moving the top of the smartphone (where the antenna is located) along the surface of the terminal, lingering for 1-2 seconds at different points.
Frequent errors and ways to fix them
Owners of Xiaomi Redmi 9 often report spontaneously turning off the module or inability to turn it on after the system update. This may be due to a conflict of software components. First of all, try resetting the network settings: Settings → Connections and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
Another common problem is conflict with other applications that use NFC, such as tag readers or antiviruses, and try temporarily disabling or uninstalling newly installed applications that have access to the communication module.
⚠️ Note: If after all the manipulations the module does not work and is not determined by the system even in the engineering menu, there is a high probability of hardware malfunction of the antenna or plume, especially if the phone fell down.
In rare cases, it helps to completely flash the device to a stable version of the global firmware, but it is a complex procedure that requires unlocking the bootloader and having a computer. If the phone is warranty, you should contact an authorized service center for diagnosis.
💡
In 80% of cases, the problem is solved by changing the region in the settings or correctly configuring HCE, hardware breakdowns are rare.
