The modern smartphone has long since ceased to be just a means of communication, turning into a full-fledged digital wallet that is always at hand. Owners of Xiaomi, Redmi and POCO devices often wonder how to quickly and safely pay for purchases in stores with a single touch. The setup process can seem difficult due to the abundance of security settings and various versions of the operating system, but with the right approach takes only a few minutes.
Contactless payment is based on NFC (Near Field Communication), which is built into most of the current models of the Chinese brand. However, having a module is only half the battle; it is critical to properly configure the software and link bank cards through reliable services. In this article, we will examine all the nuances, from checking the hardware to solving common errors when trying to pay.
It is worth considering that depending on the region of use and the firmware version (Global, EU or China), the interface and methods available may vary slightly. For example, some models require unlocking the bootloader or using specific versions of applications for payment functions.
Checking for the presence of an NFC module and activating it
Before you start installing applications, you need to make sure that your device technically supports contactless communication. Not all budget Xiaomi models are equipped with the appropriate chip, so checking the hardware part is the first must. Usually the antenna of the module is located at the top of the case or next to the camera block, which is important to consider when applying the smartphone to the terminal.
For quick diagnostics, use the built-in system tools. Go to settings, search for the word "NFC" or find the appropriate item in the "Connections and Sharing" section. If the switch is not on the menu, chances are that hardware support in your model is not provided by the manufacturer.
You can also use third-party utilities for detailed diagnostics, and the NFC Check or AIDA64 app will show not only the chip's presence, but also its status, protocol version and specifications, which is especially useful if the phone has been purchased used or restored.
- ๐ฑ Go to Settings. โ Connections and sharing.
- ๐ Find a point. NFC and activate the slider.
- ๐ Make sure that the โPayment Itemโ menu selects the โPayment Itemโ SIM-"card "HCE Wallet".
Once the module is activated, the system can request confirmation to use Google services. Agree, because it is through GMS (Google Mobile Services) that tokenization of your card data takes place. Without this step, adding cards to Google Pay will not be possible.
โ ๏ธ Warning: If you've been reflashing your phone from the Chinese version to the global version, make sure that Google services remain on the system (CN ROM) install GMS The pay will not work.
Setting up Google Pay on Xiaomi smartphones
The main payment tool for Android is Google Pay (now often integrated into Google Wallet).To work correctly on Xiaomi devices, it is important not only to install the application, but also to properly configure access rights and priorities. MIUI or HyperOS system is known for its aggressive energy savings, which can block the background processes of payment systems.
First, download the official app from the Play Market Store. If your account is tied to a region where the service is not officially supported, you may need to change the region in your Google account settings or use alternative installation methods, but for most CIS users, the service works normally.
Once installed, open the app and click "Add card" button. The camera automatically reads the data from the plastic, but manual input is also possible. SMS-It's important that the phone has a lock screen on it (PIN-code, pattern lock or fingerprint, otherwise the security system will not allow you to save the card.
โ๏ธ Checking the settings of Google Pay
Pay special attention to battery settings. Go to Settings โ Apps โ All apps โ search for Google Pay. In Activity Control, select No Limits, which will prevent the system from shutting down the service to save charge, which often causes payment errors.
- ๐ณ Open the Google Pay app and log in to your account.
- ๐ Add the bank card by following the instructions on the screen.
- ๐ Install a reliable method to unlock the screen if it is not already specified.

If the Google Pay app doesnโt see the map, try clearing the cache of the Google Play Services app in your phoneโs settings, then restart the device.
Alternative ways: Mi Pay and banking applications
In addition to the Google ecosystem, Xiaomi is developing its own payment system Mi Pay, which is not available in all regions and is supported by a limited list of banks, but sometimes works more stable on devices with Chinese firmware.
Many large banks release their own applications with NFC payment function. For example, Sberbank Online, Tinkoff or Alfa-Bank applications may have a built-in payment module, in which case, in the NFC settings, you need to choose a specific banking application rather than Google Pay as the โSecurity Elementโ.
To switch between payment systems, you use the NFC settings menu, where you choose which application will open by default when you bring your phone to the terminal, which is convenient if you use cards from different banks that require different processing methods.
| Payment method | Dependence on Google | Supporting banks | Stability on MIUI |
|---|---|---|---|
| Google Pay | Complete. | Tall. | Tall. |
| Mi Pay | Not required | Low. | Medium |
| Bank's annex | Partial | Depends on the bank. | Tall. |
Using specific bank apps is often the only option for cardholders who are not supported by Google Pay in your area, but itโs worth remembering security: third-party apps can ask for more permissions than necessary.
โ ๏ธ Note: When using Mi Pay or bank apps, make sure that the settings are in place. NFC The default application is chosen, and the priority conflict can cause the phone to simply not respond to the terminal.
Solving Payment Problems on Xiaomi and Redmi
Even with the right setup, users can encounter a situation where the terminal is not reading the phone or emits an error. Often the problem lies in the case. Metalized cases, magnetic clasp cases or too thick plastic shield the NFC signal, making payment impossible.
Another common cause is demagnetization or damage to the antenna module after the device falls, and if the phone has previously fallen on a hard surface, the antenna's contact with the motherboard may have been disrupted, and in such cases, the software methods are powerless, repairs are required.
Errors can also occur due to the outdated version of the software. Google regularly updates security protocols, and older versions of Google Play services may no longer be supported by banks.
- ๐ต Take your phone and try to pay again.
- ๐ Restart the device to reset service errors NFC.
- ๐ก Make sure the internet (mobile or Wi-Fi) is enabled for tokenization.
If nothing works, try removing the card from the app and adding it again, and sometimes the token file gets corrupted, and simply re-associating it solves the problem.
What to do if you say "check the connection"
Security issues with contactless payment
The security of the card when using Xiaomi for payment is ensured by the technology of tokenization. When you add a card to your phone, its real number is not stored in the device memory or transmitted to the terminal, instead, a unique virtual account (token) is generated that is valid only for a specific device.
Even if you lose your phone, an attacker will not be able to pay for a purchase without unlocking the screen. 1000-3000 RUB, depends on the bank) the system will require input PIN-biometric verification, even if the phone is unlocked.
Xiaomi owners with an unlocked bootloader (Root rights) should be careful. Having superuser rights can lead to the blocking of payment applications by banks for security reasons.

Tokenization of card data makes payment by phone even more secure than using physical plastic, since real card data never leaves the bankโs secure server.
Check the list of devices that have access to your Google account and banking app regularly, and removing old or unknown gadgets is a good digital hygiene practice.
