You will learn which apps are relevant today, how to set up Mi Pay correctly or use alternative services for uninterrupted payment in stores.

Before you start setting up, you need to make sure that your gadget is technically ready. Not all budget models are equipped with the necessary equipment for contactless data transmission, which is a critical success factor. Performance check is the first and most important step that will save you time and nerves during the setup process.
Checking for NFC and preparing the device
The foundation for connecting a credit card is the NFC (Near Field Communication) module in your smartphone, which is responsible for wireless data transmission over a short distance, allowing the phone to simulate a plastic card when you bring it to the terminal. If your device, for example, some versions of the Redmi Note or older Xiaomi models, does not have this module, then contactless payment via the phone is technically impossible by any software methods.
To check for technology, the easiest way to look at the system settings or the specification on the box is to use quick access through the notification curtain, where the corresponding switch is often located. The lack of this feature makes it impossible to use native payment tools such as Google Pay or Mi Pay, and requires finding alternative solutions, such as, QR-code.
💡
If you don’t find an NFC switch in the curtain, type “NFC” into the phone’s settings search – the system will tell you if the module is in your device.
Beyond hardware, it’s important to make sure the software is up to date: Older versions of the MIUI shell or HyperOS may not support the latest security protocols required by banks. Updating to the latest available version is not only new features, but also critical security patches for financial transactions.
⚠️ Attention: Inclusion NFC It's a faster battery life, but it's a little bit less. If you're not planning on using your phone's payment right now, you'd better turn it off in the settings to save energy.
Choosing a payment method: Mi Pay, Google Pay or third-party apps
The Android ecosystem offers several ways to link cards, but the choice of the specific method depends on the region of use and the type of credit card you have. For a long time, the de facto standard was Google Pay (now Google Wallet), which provided maximum compatibility, but in a number of countries, including Russia, its functionality for local bank cards is limited, which has brought other solutions to the fore.
Xiaomi has developed its own Mi Pay service, which allows you to add cards directly to the system without using Google services, a solution that is especially relevant for users who do not want to depend on third-party accounts or use devices without Google services.
There are also specialized applications from banks and payment systems that can emulate a card even in the absence of standard payment services, such as Mir Pay or large banks’ own wallets, which allow you to pay for purchases using HCE (Host Card Emulation) technology, and the choice of a specific tool is dictated by which cards you use most often and in which stores you plan to pay.
- 📱 Google Wallet: A universal solution for international maps and countries where the service is fully operational.
- 💳 Mi Pay: Xiaomi’s native system that requires separate setup and support from the issuing bank.
- 🏦 Banking applications: Direct integration through bank software (e.g. Mir Pay) that works independently of a Google account.
Instructions: How to add a map through Google Wallet
For cardholders supported by international payment systems, the classic method is the use of the service from Google. the process of adding is as standardized as possible and does not differ much on different Xiaomi models, the main condition is the presence of a Google account and the installed Google Wallet application (or Google Pay depending on the version of Android).
Once the app is launched, the system will suggest adding the first card, you can scan the plastic with the camera or enter the data manually. Automatic reading through the camera greatly speeds up the process and minimizes the risk of error when entering a long number. Once the data is entered, the bank will send the verification code via SMS or through the bank application to confirm ownership of the account.
☑️ Checklist for map addition
It's important to note that when you add a card, you have a tokenization process, which means that your real card number is not passed to the merchant or stored in the open on the phone, instead, you create a unique digital token that is used for the transaction, and even if the phone is hacked, the attackers will not have access to your real account data.
⚠️ Note: When adding a map to Google Wallet, you may need to unlock the screen.Make sure the phone has a reliable security method installed (PIN-code, pattern lock or biometrics, as this is a security requirement.
Setup Mi Pay on smartphones Xiaomi
Mi Pay is an alternative to Google’s solutions and is integrated directly into the MIUI or HyperOS shell. To use this method, your bank must support this technology. The list of partners is constantly changing, so it is better to check the latest information on the manufacturer’s official website or in the bank’s application.
The setup process starts with adding a map to the Mi Wallet app, which, unlike Google, may require additional verification through the app. SIM-The Mi Wallet interface often offers deeper integration with the system, allowing, for example, to quickly open the card to display the barcode in the subway or stores.

Solving Payment Problems on Xiaomi
Even when set up correctly, users can experience payment difficulties. One of the most common problems is that the phone can't see the terminal or the transaction is interrupted.

To fix this, go to Settings → Connection & Sharing → NFC. Find the default payment or contact payments option and select the app you want (like Google Pay or Mir Pay). It’s also worth checking if the unblocked payment option is enabled if you want to make purchases without entering the screen pin (although it’s less secure).
