Whether you are a new smartphone owner or just decided to optimize your settings, this information will be useful for you. We will touch on security issues, as the financial sector requires special attention to detail and protection of personal data.
What is NFC and how does it work in Xiaomi Mi 10?
NFC (Near Field Communication) is a short-range wireless technology that allows data to be exchanged between devices no more than 10 centimeters away. In the context of the Xiaomi Mi 10, this technology is used primarily to emulate plastic cards. When you bring your phone to the terminal, the embedded chip generates a unique token that is transmitted to the reader, simulating the attachment of a physical card.
It is important to understand that the NFC module itself does not store money; it only transmits encrypted data necessary to authorize a transaction. Security of the process is provided by several layers of protection, including card data tokenization and biometric authentication (fingerprint or face scanning). In the Xiaomi Mi 10, the NFC antenna is located at the top of the case, next to the camera module, which should be considered when attaching the device to the terminal.
There are several modes of operation of the module, but for payment, card emulation mode is used. This mode allows the smartphone to act as a payment tool. Android, which runs the shell MIUI, has built-in support for this technology, but to work properly requires Google services or alternative payment systems, depending on the region of use.
⚠️ Attention: When in use NFC In public places, always monitor the unlock screen. Do not bring your phone to unknown readers, as it is theoretically possible to read data if the device is unlocked and is in active emulation mode.
The technical implementation in the Xiaomi Mi 10 supports HCE (Host Card Emulation) standards, which means that payment data processing takes place in a secure environment by the operating system, rather than on a separate Secure Element chip, as it was in earlier models.This makes the process more flexible, but requires software relevance and security certificates from Google.
Verification of module availability and initial activation
Before you start map binding, you need to make sure that the NFC module is technically sound and activated in the system. In the Xiaomi Mi 10 model, the module is guaranteed by the device specification, but there may be nuances in the software, especially if the phone is bought in China and re-flashed to a global version. The first step should always be to visually check the settings.
To activate the function, perform the following actions:
- 📱 Open the menu Settings of your smartphone.
- 🔍 Find the Connection and Sharing section or search by settings by entering the request"NFC".
- ⚡ Activate the slider Include NFC, putting him in an active position.
- 💳 In the menu "Location of the security element" select the option HCE Wallet (or Google Pay if offered).
After the notification curtain is turned on, the corresponding icon in the form of the letter "N" should appear. If the icon is not displayed but the switch is active, this is normal for some versions of MIUI. It is also important to check that the "Security and Privacy" section does not set restrictions for the applications that will be used for payment.
There's a quick way to activate through the control panel. Swipe from top to bottom to open the control center, and find the NFC icon. If you don't see it in the front row, click on the pencil (edit) and add a shortcut to the main screen of the panel, which will allow you to turn the module on and off with a single touch, which saves battery power when the function is not needed.
It’s worth noting that in some regions or on certain versions of firmware, the menu name may vary slightly. For example, in the Chinese version of MIUI, the path may look like Additional Features → NFC. If you can’t find settings, make sure your Mi Account is tied to the region where Google services work correctly.
Google Pay settings and bank card binding
The main tool for contactless payment on Xiaomi smartphones with Google services is the Google Pay application (or Google Wallet in new versions).The setup process is as automated as possible, but requires certain security conditions. Before you start, make sure that the device does not have superuser rights (Root) and the bootloader is not unlocked, as this will lead to the blocking of the payment function.
Instructions for adding a map:
- 💳 Download and install the Google Pay app from the Play Market Store.
- 👤 Log in to your Google account that is used on your device.
- ➕ Click the Add Card button and select the add method (camera scan or manual input).
- 📝 Enter the card details, including CVC-code and expiration date, and agree to the terms of the issuing bank.
- 📲 Confirm the binding through SMS-code or through your bank’s application.
Once successfully linked, the card will become the default card, which means that it will be used to pay when you unlock your phone, and you can add an unlimited number of cards and switch between them directly in the application interface before paying, or by selecting the card you want when you access the terminal.
⚠️ Note: If you try to add a card, you get a message that “the device does not meet security requirements,” check for third-party applications that may block your work. NFC, Or a modified firmware, 90% of the time, the problem is solved by returning the stock version of the software.
Google Pay requires that the phone has the latest version of Google Play Services installed. The app periodically checks the integrity of the system. If you use Xiaomi Mi 10 with global firmware, there should be no problems. In the case of the Chinese version and manual installation of Google services (GMS), conflicts may occur that require additional adjustment of permissions in the app menu.
☑️ Checking readiness for payment
Alternative payment methods: Mi Pay and banking applications
In addition to the Google ecosystem, Xiaomi Mi 10 owners can use the company’s own service, Mi Pay.This service is integrated directly into the MIUI shell and operates independently of Google Pay, although it uses the same NFC module. The main advantage of Mi Pay is the ability to work in some regions where Google Pay is limited, as well as deeper integration with Xiaomi’s system security features.
To set up Mi Pay, you need to:
- 🌏 Make sure that the region in the phone settings is set to supported (e.g. Russia, India, China).
- 🆔 Sign in to your Mi Account account.
- 💳 Open the Cards or Wallet app and select the Mi Pay section.
- ➕ Add a bank card by following the instructions on the screen.
Many banks also release their own NFC-enabled applications (such as Mir Pay or specific bank applications), which are similar in principle: the app emulates the card through the Host Card Emulation system interface, and when installing such an application, the system can request permission to use NFC and install it as the default payment method.
It is important to understand the difference between these methods: Google Pay uses tokenization on the server side of Google, which is considered more secure for the user, since the seller does not see the card data. Mi Pay and banking applications can use different tokenization schemes. The choice of payment method depends on which cards your bank supports and in which country you are located.
The table below compares the main features of the different payment methods on Xiaomi Mi 10:
| Parameter | Google Pay | Mi Pay | Bank's annex |
|---|---|---|---|
| Account dependency | Google Account | Mi Account | Bank account |
| Security | High (token) | Tall. | Medium/High |
| Working without the Internet | Yeah (offline tokens) | Yes. | Depends on the bank. |
| Support to regions | Global | Limited. | Local. |
What to do if none of the methods work?
Payment process in the store: step-by-step instructions
The moment of payment is as simple as possible for the user, but knowing the nuances will help to avoid awkward situations at the cashier. The main rule is that the terminal must support contactless payment (wave or smartphone icon), the process is as follows: you unlock the smartphone, bring it to the terminal and wait for confirmation.
Detailed algorithm of actions:
- 🔓 Unlock the Xiaomi Mi 10 screen (Pin code, print or Face) ID). Payment will not be paid if the screen is turned off.
- 📲 Hold the top of the back of the phone to the terminal reading area (usually the area with the logo). PayPass/PayWave).
- ⏳ Don't put your phone away. Hold it. 1-2 seconds until you feel vibration or hear a beep.
- ✅ Wait for the message "Payed" on the phone screen and check on the terminal.
It's important to keep the phone flat without shifting it while reading. The NFC module in the Xiaomi Mi 10 has good sensitivity, but metal cases or cards lying on the back can shield the signal. If the payment didn't go through the first time, try changing the angle or removing the case.
In some cases, when you buy a lot of money, the terminal can request a PIN, which is standard banking security, and the smartphone is just a transmitter, and enter the code on the terminal as if you were using a plastic card.
💡
Tip: Before going to the store, make sure the phone's battery is above 10-15%. At critically low charge, some smartphone models can turn off the NFC module to save power, even if the phone is still on.
Solution and troubleshooting
Despite the technology's fine-tuning, users can encounter errors, and the most common problem is "Pay failed" or the terminal's lack of response. The first thing you need to do is check if the reset protection has worked. If you unlock the bootloader, Google Pay will stop working until the stock state returns.
Other common problems and solutions:
- ❌ Terminal doesn't see phone: Check if it's on NFC. Make sure the case does not contain metal plates or magnets. Try to hold the phone with another part of the case.
- ❌ No card added: Check the Internet connection. Make sure the bank supports tokenization for mobile. Try re-issue the card in the bank's app.
- ❌ Security error: Remove newly installed apps that may have access to the system or clipboard. check for updates for Google Play Services.
If the problem is systemic, you can try resetting your NFC settings. Go to Settings → Connection & Sharing → NFC and find the reset point (if available), or just turn off and turn on the module again. In extreme cases, cleaning the cache of the Google Pay application through the application management menu helps.
⚠️ Warning: Never try to use third-party patches or mods to bypass security checks (SafetyNet/Play Integrity, if you are not an advanced user, may result in a Google account being blocked or financial data being leaked.
It’s also worth considering that some older terminals may not support the new encryption protocols used by modern smartphones, in which case the only solution is to use a physical card, but in 2026 there are very few such terminals.
