Xiaomi smartphone owners, including the popular Redmi 8, often face the need to adapt the payment process after changing payment systems. While contactless payment via NFC was a standard feature, now users have to look for workarounds for linking Sberbank cards, due to the fact that Google Pay officially ceased to support cards issued by Russian banks after certain dates, which requires new technical solutions.
However, the Android ecosystem provides flexible tools for managing finances. - Xiaomi's shell-enabled devices MIUI You can configure alternative methods of conducting transactions, or HyperOS. NFC-The chip in the phone has not gone anywhere and continues to function, requiring only the correct software configuration and the selection of the appropriate intermediary application.
In this article, we will discuss in detail the current methods of payment with a phone based on Redmi 8.We will look at working with Google system services, using cloud payments MIR Pay, as well as installing third-party applications for emulation of cards. You will learn what security settings you need to activate and how to avoid blocking funds when trying to pay in the terminal.
Verification of hardware compatibility and NFC status
The first step before setting up any payment service is to be sure that your particular instance of your smartphone supports near-term telecommunications technology.The Redmi 8 model came in various versions for different markets, and the presence of the NFC module is not 100% guaranteed in all regional versions.
In the menu that opens, find a section that may be called Connection and Sharing or simply Additional Features, depending on the version of the MIUI firmware. Inside this section, look for NFC. If such an item is not on the list, chances are your device does not have the necessary chip, and contactless payment is physically impossible without the use of external readers.
⚠️ Attention: Availability of logo NFC The box or specifications on the seller's website do not always guarantee the module's performance in your firmware (CN) This component is often lacking, while global (Global) components usually lack it.
If you find a point, move the switch to the active position. The system can request confirmation or offer to configure the security element. Make sure that the default application for payment is selected in the NFC settings, although at this stage this may be a standard Android Beam or an empty value. It is also worth checking whether the HCE (Host Card Emulation) mode is enabled, which allows you to emulate the card software way.
Google Pay and system restrictions
The traditional method of payment through Google Pay (now Google Wallet) in Russia is operating with serious restrictions, the application continues to function for cards of foreign banks, however, Sberbank cards issued in Russia cannot be added in the classic way due to sanctions by Google.
However, Google Pay itself remains an important system component for Android, and many terminals read the token generated by the service. Redmi 8 users can use workarounds such as creating virtual cards or using cards from other payment systems that are supported in the wallet, but for direct payment with a Sber card, this method in its pure form is now ineffective.
It is worth noting that having Root or Bootloader rights can result in any payment application being blocked for security reasons. Google Pay and banking customers use Google Play Protect to verify system integrity. If the phone is deemed unsafe, the payment function will not be available until the firmware is restored to factory state.
Use of the MIR Pay application for Sberbank cards
The most stable and officially supported payment method on Xiaomi smartphones is the use of the national payment system MIR Pay. This application allows you to add Sberbank cards issued on the basis of the MIR payment system, and pay for purchases by them in any terminals that support contactless. To start, you need to download the installation file or find an application in the GetApps or RuStore store.
The process of adding a map to MIR Pay on Redmi 8 is like this: Once installed, launch the app and log in using the phone number attached to the card. Press the add new card button and select your bank from the list. The system will suggest scanning the card with the camera or entering the data manually. CVC-code and validity period will require confirmation via SMS.
☑️ Setting up MIR Pay
It's important to understand that to work with MIR Pay, the NFC module must be active and the phone screen unlocked. Unlike older methods, you don't have to select a card on the menu every time it's installed by default. The application creates a secure token that is transmitted to the terminal, which provides a high level of security for the transaction.
⚠️ Note: For successful payment through MIR Pay card should be issued on the payment system MIR. Visa and MasterCard cards issued by Sberbank, this application will not be able to add.
Alternative methods: QR-codes and FPS
In the context of the classical NFC map-to-card Visa/MasterCard Sberbank does not work directly through Google Pay, the technology of fast payments comes to the fore QR-The SberBank Online app on Android has a built-in scanner that allows you to pay for purchases in stores that support SBP. NFC, It requires the Internet and a running application.
To pay through QR-Open the bank's app, select Payment, and click on the scanner icon, point the camera at the code on the checkout or check, and the amount is often charged automatically, and you only have to confirm the transaction. This method works on any Xiaomi phone, even if it doesn’t have a module. NFC.
Another option is to use quick payment widgets. You can take out the SberBank Online widget or MIR Pay directly to the Redmi 8 desktop, which speeds up access to the single-tap payment feature. Some users also use cashback aggregators that generate their own payment options. QR-payment codes with a refund of part of the funds.
💡
Configure the Pay QR widget on the home screen for quick access to payment without logging into the app’s deep menu.
Third-party solutions and card emulator
For advanced users who want to emulate the card they have on their phone (even if it is Visa/MasterCard), there are emulator applications such as Card Emulator or Wallet Pass. These programs are not official banking customers and work on the principle of reading data from a physical card and writing them to the phone’s memory to simulate the response of the chip.
The process of setting up in such applications on Redmi 8 requires care.
- 📲 Install an emulator application (often available only in the form) APK-file, since removed from the Play Market).
- 🔐 Provide the application with the right to work with NFC and, in some cases, special permissions through ADB.
- 💳 Read the card data through NFC (If the chip allows, or enter data manually.
- 🔄 Activate the emulation mode before bringing the phone to the terminal.
The main difficulty is that modern bank cards have enhanced copy protection, and simply reading the card number is often not enough to conduct a transaction, since the terminal requests a dynamic token or cryptogram that static emulation cannot provide, so this method does not work with all terminals and cards.

|---|---|---|---|---|
| Google Pay (officially) | No. | No (for new cards) | Yes. | Low. |
| MIR Pay | No. | Yes. | Yes. | Tall. |

Security setting and troubleshooting
For the smooth operation of any payment tools on Xiaomi Redmi 8, it is critically important to correctly configure security settings. First of all, the device must have a reliable method of locking the screen: PIN-A code, a pattern lock or a fingerprint, and payment systems are blocking the operation. NFC, If the phone is not password protected, it is considered a vulnerability.
A frequent problem is the aggressive battery saving characteristic of MIUI shells. The system can automatically close the background processes of payment applications, which leads to payment failures. To avoid this, go to Settings → Applications → Select your payment application (such as MIR Pay) → Saving charge and select No Limits mode.
What if the terminal can’t see the phone?
It's also worth checking the date and time settings. If the time on the phone is knocked down, the security certificates may be invalid, and the connection to the bank server or terminal will not be established. Use automatic time synchronization over the network.
⚠️ Note: When installing applications from unknown sources (APK-Android will issue warnings, be sure that the download source is reliable so as not to infect the device with malware that steals card data.
