Smartphone owners Xiaomi and Redmi often face the need to set up contactless payment after changes in the operating conditions of payment systems. Despite the fact that the usual services have become unavailable, the ecosystem Android provides reliable alternatives. The setup process may seem complicated due to the abundance of information on the Internet, but in reality it takes only a few minutes if you have modern equipment.
The main tool for making purchases is now the application Mir Pay, which completely replaces the functionality of remote services. Your smartphone turns into a full-fledged payment terminal, allowing you to pay in stores, cafes and gas stations with a simple touch. The key condition for success is the presence of a module NFC in your device and an active card of the national payment system World.
In this article we will analyze each stage in detail: from checking technical compatibility to solving common errors during transactions. You will learn how to correctly add a card to your phone's security system and what nuances should be taken into account when using different firmware versions MIUI or HyperOS. Follow the instructions step by step to restore the comfort of cashless payments.
Checking technical compatibility and preparing the device
The first step before starting setup is to make sure that your device is physically capable of transmitting payment data. Not all models in the budget segment are equipped with the necessary module, so a check must be carried out before installing any software. Go to the phone settings and find the section responsible for connections or additional functions.
Activate the switch NFCif it is off. In most shells MIUI this item is located along the path Settings → Connection and sharing → NFC. After turning on, the system may offer to select the default application for contactless payment - for now, leave this choice empty or select a system value, since we will configure specific software a little later.
⚠️ Attention: If there is no NFC item in the settings of your smartphone, it is impossible to add it using software methods. In this case, contactless payment by phone is not available, and you will have to use physical cards or stickers.
It is also critical to check the version of the operating system. For payment applications to work correctly, version 6.0 and higher is required, but for maximum security and stability it is recommended to use more recent versions, starting with Android 10. Firmware updates often correct errors in the operation of the radio module, which is responsible for communication with the terminal. Android version 6.0 and higher, however, for maximum security and stability, it is recommended to use more recent versions, starting with Android 10. Firmware updates often correct errors in the operation of the radio module, which is responsible for communication with the terminal.
Before setting up payment, clean the back cover of the smartphone from metal stickers or cases with magnetic inserts - they can shield the NFC signal and lead to payment failures.
Installation and initial setup of the Mir Pay application
Since the application has been removed from the official store Google Play in the Russian Federation, it must be downloaded from alternative sources. The safest option is the official website of the developer or verified application directories, such as RuStore. Downloading the installation file from unverified sources may lead to infection of the device with malware.
The installation process is standard for the platform Android. After downloading .apk the file, the system will ask for permission to install from unknown sources. You need to grant this permission to the browser or file manager through which you are running the installation. Modern versions MIUI have strict security policies, so you may need to wait for 10 seconds before confirming the action.
When you first launch the application, it will ask for a number of permissions necessary for it to function. These include access to the camera (for scanning the map), geolocation and phone. Refusal to grant these rights will make the service impossible to operate. The application will automatically check for security certificates on your device.
- 📱 Download the current version of the Mir Pay application from the official resource or the RuStore store.
- 🔒 Allow installation of applications from unknown sources in the phone security settings.
- ✅ Grant all requested permissions upon first launch service.
- 💳 Accept the user agreement and privacy policy inside the application.
☑️ Ready for installation
Adding a Sberbank card to the payment service
The process of linking a bank card is as automated and intuitive as possible. After logging into the application, click the button to add a new payment instrument. You can enter the information manually or use your smartphone camera to scan the front of the card. The second method significantly speeds up the process and minimizes the risk of a typo in a long account number.
The system will ask you to confirm your identity using the code from SMS, which will be sent to the phone number linked to the card at the bank. This is a mandatory verification procedure to ensure that only the account owner can add it to the payment service. Enter the received code in the appropriate field of the application.
At the next stage, you will be asked to come up pin code to enter the Mir Pay application itself. This code is different from your bank card PIN and serves as an additional security barrier. If an attacker gains access to an unlocked phone, he will still not be able to make a payment without knowing this code.
⚠️ Attention: When entering card details, make sure that the expiration date and CVV/CVC code are entered correctly. An error in even one digit will result in the bank refusing to link the card.
After successful verification, the card will appear in the list of available funds. You can set it as the main one by default or switch between several cards directly in the application interface before paying. The interface supports a dark theme and large fonts for ease of use.
What to do if the bank rejects the card?
If you receive an error when adding a Sberbank card, make sure that the card is not blocked and there is a positive balance on it. Also check if it has expired. In rare cases, a reissue of a card with tokenization support is required, although for Mir cards this is required extremely rarely.
Setting up NFC and selecting a default application
For contactless payment to work correctly, you need to indicate to the system which application should process transactions. In your smartphone settings, go to the NFC section and find the “Contactless payment” or “Default payment” item. In the list that opens, select Mir Pay.
It is important to make sure that the phone screen is on when you bring it to the terminal. Unlike some other systems, Android requires an active session to transfer the encrypted token. Locking the screen during a transaction will interrupt the process and the terminal will display a communication error.
Some users are faced with a situation where the phone prompts you to select an application only after the first time you bring it to the terminal. This is normal system behavior. In the window that appears, select Mir Pay and check the box “Always” so as not to perform this action for every purchase.
| Settings parameter | Recommended value | Where to find |
|---|---|---|
| NFC module | Enabled | Settings → Connection |
| Payment by default | Mir Pay | Settings → NFC |
| Secure element | HCE (emulation host) | Settings → NFC (add.) |
| Payment screen | Unlocked | System requirement |
Correctly setting the default application in the NFC menu is critical - without In this case, the phone may try to use the Google Pay system application, which does not work with Russian bank cards.
The payment process at retail outlets and online
Making a purchase using a smartphone is practically no different from using a physical plastic card. Go to the cash register and wait until the cashier enters the amount and the terminal is ready to accept payment. Unlock your smartphone and launch the application Mir Payby selecting the desired card.
Bring the top of the back cover of the phone to the reading area of the terminal. This area is usually indicated by a wave icon or is located at the top of the device. Hold the phone for 1-2 seconds until a checkmark appears on the smartphone screen and the terminal beeps.
For amounts over a certain limit (usually 1000 rubles, but depends on the bank and terminal settings) you may need to enter PIN code from a bank card. Enter it on the terminal keyboard, not on the phone screen. Once the transaction is confirmed, the check can be sent to you electronically or printed.
- 💳 Unlock your smartphone and open the Mir Pay application before approaching the checkout.
- 📡 Bring the device to the terminal with the upper part of the case.
- 🔢 Enter the PIN code on the terminal if the purchase amount exceeds the contactless payment limit.
- ✅ Wait for the green indicator and sound confirmation of success.
Online payment is also supported in many applications and online stores. When choosing a payment method, select “Google Pay” or “Pay by phone”, and the system will redirect you to the Mir Pay application to confirm the transaction with biometrics or password.
Solving common problems and errors
Despite the well-functioning system, users may encounter technical failures. The most common error is “Unable to contact the terminal.” This may be caused by moving the phone away from the reader too quickly or by having a thick protective case blocking the signal.
If the application gives an error when adding a card, check your Internet connection. Verification requires a stable communication channel with the bank and payment system servers. Try switching from Wi-Fi to mobile data or vice versa.
⚠️ Attention: If the terminal does not read the card for a long time, do not touch the phone repeatedly in a row. This may lead to temporary blocking of a payment attempt by the bank due to suspicion of fraud.
If the payment does not go through at a specific terminal, try using another card or physical media. Some older terminal models may not work correctly with the host emulation protocols used in Android. Updating the phone's firmware also often solves compatibility problems.
Why doesn't payment work after updating MIUI?
After major shell updates, NFC settings may be reset to factory settings. Go to the NFC menu and re-select Mir Pay as the default application, and also double-check the module's operating status.
Security measures and data protection
Using a smartphone to pay is a safer method than using a plastic card. During the transaction, it is not the real card number that is transmitted, but a unique encrypted token. Even if the data is intercepted, attackers will not be able to use it to re-pay or clone the card.
Always set a reliable screen lock method: pattern, complex password or biometrics (fingerprint, face). This is the first line of defense that protects your financial data in case of loss or theft of your device.
Regularly update the Mir Pay application and smartphone operating system. Developers constantly release security patches that close vulnerabilities. Do not ignore notifications about available updates in the application store.
⚠️ Attention: Never share SMS codes with anyone, even if the caller introduces himself as a bank employee. Bank employees never ask for these codes. Enter them only in the official application.
Is it possible to pay by phone without the Internet?
Yes, to make a payment in a store, you do not need active Internet on your phone. Tokens are generated in advance and stored in a secure device element. However, the Internet is needed for initial setup, adding cards and receiving balance notifications.
Is it safe to store a Sberbank card in Mir Pay?
Absolutely safe. Card data is not stored in clear form on the phone. Tokenization technology is used, in which real data is replaced with a digital key, which is useless outside a specific device.
What should I do if I lost my phone?
Urgently call the bank at 900 or through the app of another device to block the cards. Also use the “Find My Device” service from Google or Xiaomi to remotely erase all data from your phone.
Does payment work on an unlocked (Root) phone?
In most cases, payment applications refuse to work on devices with rooted rights for security reasons. You may need to hide root access using special utilities, but this does not guarantee stable operation.
Do you need to open the application before each payment?
Yes, unlike some other systems, Mir Pay requires the active launch of the application and selection of the card before presenting it to the terminal to confirm the payment intent and verify the login PIN code.
