Xiaomi’s modern smartphones, including the Poco and Redmi sub-brands, have long been universal tools that replace wallets, bank cards and keys. The near-to-contact technology known as NFC allows you to make purchases with one touch of your phone to the terminal, which greatly speeds up the process at the checkout. However, owners of devices based on the Android operating system, especially after a series of geopolitical changes, often face difficulties in initial setting up or restoring functionality.
In this article, we will discuss in detail how to activate the module, correctly configure payment applications and what alternative payment methods exist if standard services are not available. You will learn about the intricacies of the chips in the shell of MIUI and HyperOS, and also get answers to security questions when using virtual cards.
Technical capability check and module activation
Before you start setting up payment systems, you need to make sure that your Xiaomi or Poco device is physically equipped with the necessary module.Not all budget models, even recently released, have an NFC chip built in, so the first step should always be to check the specifications. If the module is present, it takes a few seconds to activate it through the system menu.
To turn on the function, swipe the notification curtain from top to bottom and find the NFC icon. If it is not available in quick access, go to Settings → Connection and Sharing. Here you need to move the switch to active position. Also, the item "Element Location" is often available in this menu, which is critical for correct operation.
Xiaomi smartphones can place the antenna in different places: on the back cover, around the camera module or at the top of the case. Correctly specifying the location of the antenna in the settings increases the speed of reading the terminal and reduces the number of errors in payment. Once activated, the phone will start searching for available tags, which will signal the characteristic sound or vibration when you bring it to the card.
It's worth noting that the module's constant search mode is negligible, but it affects power consumption. If you don't plan to use the payment anytime soon, it's wiser to turn off the feature to save battery life. However, for everyday use, constant activation won't harm the battery.
Google Pay and Alternative Services
The traditional payment method on Android was the service Google Pay, but its functionality for cards of Russian banks is now limited. For cardholders of foreign banks, the process remains standard: installing an application, linking a card through a camera or manual data entry, and confirmation via SMS. After that, the smartphone is ready to pay anywhere in the world where contactless payments are accepted.
For card users in Russia, the situation requires alternative solutions, such as Mir Pay (for supported devices) or specific bank services such as SberPay, Salute and other ecosystem solutions, which often require downloading the.apk installation file from the bank’s official website, as they may not be available on the Google Play store.
The process of adding a map to alternative applications is usually as follows:
- 📱 Launch the banking application and go to the profile or cards section.
- 💳 Click the "Add to Mir Pay" button or similar button for the selected service.
- 🔒 Complete the verification procedure by following the instructions on the screen.
- ✅ Install the default app for contactless payments in your phone settings.
It is important to understand that any payment system needs to unlock the device screen. Unlike some other platforms, Xiaomi does not allow transactions with the display completely off, which is a security measure. Also make sure that the NFC settings select the application that will open by default when you bring it to the terminal.

Comparison of payment systems and compatibility
The choice of payment method depends not only on the issuing bank, but also on the model of your smartphone and the version of the operating system. Some older Poco or Redmi models may not support the new encryption standards required by certain applications.
| Service | Type of card | LA requirements | Stability |
|---|---|---|---|
| Google Pay | Foreign | Android 5.0+ | Tall. |
| Mir Pay | Mir, Visa, MC (RF) | Android 9.0+ | Medium |
| SberPei. | Sberbank (RF) | Android 7.0+ | Tall. |
| Salute | Sber, Tinkoff (RF) | Android 8.0+ | Tall. |
When using third-party applications downloaded from outside the official stores, Xiaomi's security system can issue warnings about a potential threat. This is a standard reaction of MIUI antivirus, and if the file is downloaded from the official bank resource, it can be ignored by confirming the installation.
Note that HyperOS updates can change the algorithms for working with communication modules. If payment stopped working after the firmware update, check the permission settings for the payment application. It should be given full access to NFC and geolocation if it is required for work.
⚠️ Note: When installing applications from unknown sources, the system may block startup, in which case you need to go to the security settings and allow installation for the specific browser or file manager you are using.
Solving Payment Problems on Xiaomi and Poco
Even with the right setup, users can experience situations where the terminal is not reading the phone. The most common reason is the device's incorrect positioning. Xiaomi's antenna is often in the top third of the case, so it's that part that you need to attach to the terminal, not the center or bottom of the smartphone.
Another common problem is that there's a thick case or a metal plate on the back, and the metal shields the signal, making it impossible to communicate, and if you're using a case with a magnetic clasp or metal inserts, you'll have to remove it before you pay, and you can also jam the cards in the case next to your phone.
If the terminal writes “Communication error” or “Card not found”, try the following algorithm:
- 🔄 Reboot your smartphone to reset the communication module errors.
- 📱 Make sure the screen is on and the device is unlocked.
- 💳 Check if the desired application is selected by default in the settings NFC.
- 📡 Turn off flight mode and make sure the network is available (for tokenization).
In rare cases, the problem may lie in the terminal or bank itself, if the phone does not see any terminal, but sees others. NFC-tags (such as transport cards) may be worth contacting the bank to reissue the card token, sometimes removing the card from the application and re-addition helps.
Security of contactless payments
Using NFC on Poco and Xiaomi smartphones is considered safer than paying with a physical plastic card. Each transaction uses a dynamic code (token) that is valid for only one transaction. Even if attackers intercept the signal, they will not be able to use this data to repay or cloning the card.
In addition, to make a payment above a certain limit (usually 1,000 rubles, but depends on the bank), the system will require biometric authorization or PIN entry, which means that even if you lose an unlocked phone, fraudsters will not be able to make large purchases without your fingerprint or face.
For maximum protection, it is recommended:
- 🔒 Always use a screen lock (pattern lock, PIN, biometrics).
- 🚫 Do not transfer the phone to unauthorized persons in an unlocked state.
- 👁️ Watch the screen at the time of payment so that the amount is considered correct.
- 📲 Install antivirus software and do not follow suspicious links.
The theoretical possibility of reading data from a distance by attackers is practically excluded in real conditions, especially given the protection of Xiaomi chips.
Using NFC for other tasks
The short-range module in Xiaomi phones is not only useful for payment, it opens up the possibility of automating household processes and quickly interacting with equipment, for example, you can create special tags for quickly switching profiles: "Home", "Work", "Night". By touching the tags, the phone will change the settings of the sound, turn on Wi-Fi or run the desired applications.
It's also used to pair with smart devices, with Mi True Wireless headphones, speakers, and even some Mi TV models supporting fast touch connectivity, eliminating the need to search for a device on the Bluetooth list and enter pairing codes manually.
Another useful feature is reading information from transport cards, electronic passes and even passports (where this is supported). Special applications allow you to find out the balance of the Troika, Strelka or other regional transport cards by simply attaching them to the back cover of the smartphone, which is convenient when you need to quickly check the balance without finding a terminal.
| Type of tag | Action. | Example of use |
|---|---|---|
| Transport map | Balance check | Find out the rest of Troika. |
| Smart home. | Launch of the script | Turn off the lights with a touch |
| Business card | Maintaining contact | Data exchange with the client |
| Wi-Fi tag | Auto-connection | Guest access to the office |
