The modern smartphone has long ceased to be just a device for calls, turning into a full-fledged digital wallet that is always at hand. Owners of budget but functional devices such as the Xiaomi Redmi 9C often wonder about the possibility of using NFC technology for quick purchases in stores. Unfortunately, the global version of this model, popular in the Russian market, initially lacks an integrated NFC module, making standard setting of Google Pay impossible without additional manipulation.
However, the absence of an NFC chip in the motherboard is not a sentence for those who want to pay simply by putting the phone to the terminal.There is a proven and safe way to circumvent this restriction using special tags and emulator apps. In this article, we will discuss in detail how to turn your Xiaomi Redmi 9C into a contactless payment tool, what applications will be required to emulate the card and what security nuances should be considered when using such methods.
Before you start technical actions, you need to clearly understand the physical nature of the data transfer process. NFC (Near Field Communication) requires an antenna and a controller inside the gadget, which in the 9C model are simply absent from the hardware level, which is why the software settings in the MIUI menu do not contain the item "NFC", and trying to find it there will not lead to anything.
⚠️ Note: Using third-party applications for emulation of bank cards carries certain risks. Make sure that you only download software from official sources or trusted repositories to prevent theft of payment means data.
The process of preparing a device for working with financial services requires attention to detail and strict adherence to the algorithm of actions. Any deviation from the instructions can lead to the fact that the bank’s security system will block the card or the application will stop reading the tags correctly. Below we will consider all the steps from the compatibility check to the first successful payment.
Verification of hardware compatibility and MIUI version
The first step before any manipulation is to accurately determine the modification of your smartphone, the fact that the Chinese versions of the Redmi 9C sometimes equipped with an NFC module, while the global (Global) and Russian (RU) versions, which are officially supplied, most often lack this component to reduce the cost of design.
To check, go to the settings menu and find the About Phone section. Here you are interested in the "Version" line. MIUI". Click on it several times to see the full build information. If the firmware name has the letter "R" (Russia) or "E" (Europe), the probability of no build is present. NFC It's 99 percent. You can also use the hidden engineering test menu by typing in the phone app a special code.
- 📱 Enter ##6484## to log into the engineering menu CIT.
- 🔍 Find a point in the list NFC Try running the test.
- ❌ If the test gives an error or a point NFC Not listed, the module is physically missing.
It is also important to consider the version of the Android operating system on which the MIUI shell is based. Modern banking applications such as Mir Pay or tag emulators require the up-to-date version of Google Play Services security. Make sure your Redmi 9C is updated to the latest available version of the software via the Settings menu → About Phone → System Update.
If the diagnostics confirmed the absence of a chip, do not despair. The accessories market offers compact solutions in the form of labels that, in conjunction with a special application, completely simulate the operation of the built-in module, which allows you to use the phone for payment even on budget models, where the manufacturer has saved on hardware.
Necessary components for emulating payment
To do this, you'll need to purchase a physical storage medium that acts as a virtual card, a thin plastic tag with an NFC chip that sticks to the back of your smartphone or is placed inside your case, and without this physical component, software emulation on the Redmi 9C is impossible, because the phone will not have anything to do with the terminal.
The second key element is software, and you'll need an emulator app that can read and tag data from a credit card, and then manage that process when you bring your phone to the terminal, and the most stable tools that are currently being developed specifically to circumvent Google Pay's restrictions.
| Component | Appointment | Where to buy |
|---|---|---|
| NFC-marker (NTAG215/216) | Storage of tokenized card data | AliExpress, Ozon, Electronics Stores |
| Emulator app | Label control and signal simulation | |
| Banking appendix | Generation of tokens for payment |
Particular attention should be paid to the choice of labels. Cheap options can have a small amount of memory or a low response rate, which will lead to errors when paying at the checkout, where the bill goes for seconds. It is recommended to use NTAG216 tags that have enough memory to store several card profiles and have improved reading characteristics.
You will also need a stable internet connection to initially set up and download card tokens. Although the payment itself is offline, the process of activating the tag and linking the card requires communication with the bank and emulator servers. Make sure the device is on data transfer or connected to a Wi-Fi network.
💡
When you buy NFC-tag 3-5 They're cheap, but one can get damaged on a sticker, and a spare card can always be used for a second card or if you lose it.
Installation and configuration of the emulator application
Once all the components are in place, we move to the software part, and emulator installation is a critical step, because it's the app that will intercept requests from the terminal and send them to the tag, and in the face of sanctions restrictions and the absence of Google Pay, users are actively switching to alternative solutions, such as Mir Pay or specialized tag emulators.
If you use the method with a label, you need to download the application to work with NFC. In the Play Market you can find many options, but not all of them work correctly on the shell of MIUI. It is recommended to choose applications with a high rating and a large number of positive reviews from users with similar Xiaomi devices.
The installation process is as follows:
- 📥 Open Google Play Market or RuStore on your Redmi 9C.
- 🔎 In the search, enter the name of the selected emulator (for example,"NFC Tools or Specialized Emulator).
- ✅ Click the "Install" button and wait for the download to complete.
- 🔓 Provide the application with all the permissions requested, especially access to the NFC and clipboard.
After installation, you need to do a primary calibration. Launch the app and follow the instructions on the screen. It will prompt you to attach a bank card (or already installed label) to the back of the phone to read data. Even if there is no built-in NFC, the application can use the camera or other methods for the initial configuration, if it is provided by the developer.
⚠️ Note: Some antivirus programs may react to emulators as potentially dangerous activity. If you have a block, add the app to the exceptions or whitelist your antivirus protection.
The important thing is to set priorities. Android can only have one active default contactless payment app. Go to Settings → Connections → Contactless payments (the path may vary depending on the version of MIUI) and select the emulator installed by the main service.
Linking a bank card to the system
The most important step is to add your payment card to the system. Since we are talking about a situation where Google Pay does not work natively, the binding process may differ from the standard one. If you use the Mir Pay application (if it is available for your model through third-party sources) or analogues, the procedure is as close to the original as possible.
Open the app and press Add Card. The smartphone camera automatically activates to scan the front of the plastic. Make sure the lighting is sufficient and the map is on a flat surface. If automatic number recognition fails, you can manually enter the data.
To confirm the ownership of the card, the bank will request a verification code. SMS-A message or push notification in the main banking application, enter the code in the appropriate field, after successful verification, the card will appear in the list of available for payment.
Sequence of action:
1. Open the payment application.
2. Press "+" or "Add card".
3. scan the map or enter data.
4. Accept the terms of the agreement.
5. Enter the code from the SMS.
6. Wait for "Active" status.If you use the method of NFC-by the label, the process of writing card data to the label occurs inside the emulator application. You attach the card to the tag (or a phone with a tag to the card if the tag is passive and the application can record through other interfaces, which is rare), and the application encrypts the card data, writing them to the memory of the tag chip.
It is worth noting that some banks may block attempts to add cards to informal payment systems, in which case it is recommended to contact the bank or use payment system cards that are more loyal to alternative payment methods.
☑️ Checking the map binding
Payment process in the store: step-by-step instructions
When all the settings are done and the card is tied, there comes a moment of truth, the first payment in a real store. The algorithm of actions is almost identical to using standard NFC, but has its own peculiarities depending on the chosen implementation method (emulation or label).
Go to the checkout and tell the cashier you'll pay by card or phone.Unlock your Redmi 9C screen. Unlike iPhones or Samsung flagships, it may require pre-launching the payment app if the tag doesn't emulate the signal constantly (which puts the battery down a lot).
Attach the top of the back of the phone (where the tag is located) to the terminal. Keep the device still for 1-2 seconds. You should hear the characteristic sound of the terminal and feel the vibration of the phone confirming a successful readout.
- 📱 Unlock the smartphone screen before paying.
- 💳 If necessary, select the desired card in the application.
- 📡 Bring the phone to the terminal area NFC (usually upper end or center of back).
- ✅ Wait for the green indicator and check.
It is important to keep the phone tightly pressed against the terminal. Since the external tag or emulated signal may be weaker than the built-in flagship module, the distance should be minimal. If the terminal does not respond the first time, try to slightly change the angle of inclination or position of the device.
After a successful payment, a charge notice will appear on the screen. Always check the amount in the bank application to be sure that the transaction is correct. In the event of a failure, the terminal usually offers to try again or use a physical card.

Solving problems and data security
Despite its apparent simplicity, the process of setting up payments on devices without native NFC can encounter technical difficulties. One of the most common problems is application conflict. MIUI is known for its aggressive energy saving policy, which can "kill" the background processes of the emulator, which causes payment to stop.
To avoid this, you need to set up autorun and exclude the payment application from the battery optimization list. Go to Settings → Battery → Search for applications, find your emulator and select No Limits mode. Also enable autorun in the appropriate settings menu.
Security remains a priority, using third-party tags and apps requires trust in the developer, but modern encryption methods such as tokenization provide a high level of protection, and it is not your card number that is transferred when you pay, but a one-time digital code that is useless for fraudsters.
⚠️ Warning: Never pass on CVC-code (three digits on the back of the card) to unauthorized persons and do not enter it into suspicious applications that are not related to official banking services or verified emulators.
If you lose a phone with a configured tag, the first thing you need to do is block your bank card through a bank application or by phone hotline. PIN-code in the application) is less threatening, but the risk of unauthorized payments remains.
Regularly update your apps. Developers are constantly releasing patches that improve compatibility with new terminal versions and banking protocols. Ignoring updates can lead to your Redmi 9C one day not being paid.
