The modern smartphone has long since ceased to be just a phone and has become a full-fledged digital wallet that allows you to make purchases in one touch. Users of the Xiaomi ecosystem often wonder what this technology is called and why it may not work in their region. The main term you are looking for is NFC-payment (Near Field Communication), but in the interface it hides behind the names of services like Google Pay or Mi Pay.
It is important to understand that the communication module itself only transmits encrypted data to the terminal, and the direct processing of the transaction is taken over by the software. Depending on the country of use and the firmware version, the names and availability of functions can vary significantly.
Next, we’ll take a closer look at how to activate contactless payment, what apps to use, and what to do if standard methods don’t work, learn about the intricacies of security settings and understand why having a chip in a phone is only half the success.
NFC Technology: The Basis of Contactless Payments
The foundation of any phone payment is NFC technology, which allows two devices to communicate up to 10 centimeters away. In Xiaomi smartphones, this module is built into the top of the case, usually next to the main camera. It is this small chip that emulates a plastic card, giving the reader terminal a unique token instead of the real card number.
Without the active NFC module, the phone cannot be used as a means of payment, regardless of the applications installed. Many budget models of Chinese brands can come without this component to reduce the cost of construction, so always check the specifications of a particular device before buying. Having an NFC logo on the back cover or in the box is the first sign of support for the technology.
It is worth noting that NFC-The module consumes minimal energy and does not drain the battery in the background, it only activates when the smartphone is placed on the reader, which makes the technology not only convenient, but also energy efficient compared to other wireless communication methods.
💡
Turn on NFC only before payment if you’re worried about theoretical security, though modern tokens are almost impossible to intercept.
The payment system also requires a secure security element, which in modern smartphones is integrated directly into the processor or the system. SIM-This element stores cryptographic keys and ensures that the card data will not be copied by malicious actors.
Google Pay and its analogues: how it worked and works now
For a long time, the main answer to the question of “what is called payment by phone” was the application Google Pay (formerly Android Pay), a standard solution for the Android operating system, which aggregated cards of all banks and allowed you to pay for purchases in stores and applications.
In the global marketplace, Google Pay remains the dominant solution, providing the highest level of security thanks to to tokenization. When you add a card, the bank issues a virtual number, which is transmitted to the terminal, the real card number remains in the secure storage of the bank's server and never gets into the phone or to the seller.
- 📱 Tokenization: Real card data is replaced with a unique digital code for each transaction.
- 🔒 Biometrics: To confirm payment, it is necessary to unlock the fingerprint, face or PIN-code.
- 🌍 Globality: the service operates in dozens of countries, accepting everywhere where there are contactless payment terminals.
In the current environment, Russian users have to look for alternatives, as the direct link of Russian bank cards to Google Pay has been suspended, which has led to a resurgence of interest in other methods, such as payment by payment. QR-code or use of foreign bank cards.
Mi Pay: Xiaomi’s own payment system
Many owners of Xiaomi, Redmi and POCO smartphones pay attention to the built-in Mi Pay app. This is the company’s own development, which is positioned as an analogue of Google Pay, but with a juicy integration into the MIUI shell (now HyperOS).
It is important to distinguish between the global version and local implementations. In some countries, such as India or China, Mi Pay is the main payment method and supports local banking systems. However, in Europe and CIS countries, functionality is often limited or completely absent for local bank cards.
Technically, Mi Pay uses the same NFC module as Google Pay, but runs through its own authorization servers. If you have a support service in your region, you can add the card directly to the system application "Security" or a separate application Mi Wallet.
⚠️ Note: Do not try to forcibly change the region in the Mi Account settings to activate Mi Pay in unsupported countries.This may lead to account blocking or incorrect operation of the system services of the smartphone.
For users looking for a native solution from the phone maker, Mi Pay remains an interesting but often unavailable option: In most cases on global firmware, the system redirects the user to install Google Pay or offers alternative NFC use cases, such as transport cards.
Alternative payment methods for Xiaomi users in Russia
Because it's straight. NFC-Payment by card of Russian banks through Google Pay and Mi Pay is now unavailable, the market has offered a number of workarounds. QR-This method is not required by the Quick Payment System (FTP). NFC It works on any smartphone with a camera and the Internet.
The second popular option is to use virtual cards of foreign banks or cryptocurrency cards that can be linked to Google Pay, and emulator apps that mask the phone as another device or use specific protocols to conduct transactions are also gaining popularity.
Compare the main available methods:
| Payment method | NFC required | Support of Russian banks | Convenience |
|---|---|---|---|
| Google Pay (Maps of the Russian Federation) | Yes. | No. | It's not working. |
| Payment by QR (SBP) | No. | Yes. | High. |
| Mi Pay (Cards of the Russian Federation) | Yes. | No. | It's not working. |
| Bank stickers | No. | Yes. | Average. |
And the pay stickers that banks put on the back of the phone, which are the same NFC principle, but the physical chip is not inside the phone, but on the sticker, and you can pay for your purchases even on an iPhone or on an old Android phone without NFC.

How to set up and check NFC on Xiaomi
Before looking for payment methods, you need to make sure that the NFC module on your Xiaomi device is active and working correctly.Setting up takes only a few minutes and requires no special knowledge.First check the presence of the chip in the characteristics of your model on the official website.
To activate the function, do the following: Open your smartphone settings and enter "NFC" in the search bar. The system will suggest going to the corresponding menu.
☑️ Checking readiness for payment
Next, you need to select the default payment app. NFC There's a "Tap to Pay" option (or "Default Payment"). Click on it and select Google Pay or another app you use. If you don't, the phone may try to run another one. NFC-application, for example, for reading labels.
Also make sure that the security settings include screen lock.Contactless payment will not work if the phone is not installed. PIN-a code, pattern lock or password, as this is a requirement of payment security systems.
⚠️ Warning: If the phone is not responding to the terminal, remove a thick case or case with a metal insert. NFC, And the payment won't pass.
Problems with payment and ways to solve them
Even with the right setup, users may encounter errors when trying to pay for a purchase. Most often, the problem is that the phone is not read by the terminal. In this case, try to bring the top of the smartphone (where the camera is located) closer to the reader and hold for 1-2 seconds.
Sometimes rebooting helps. NFC-To do this, turn off the function in the settings, wait 10 seconds and turn it on again. If the problem persists, check the system updates in the Settings menu. → The phone. → Version. MIUI. Errors in the operation of payment modules are often corrected by security patches.
If the terminal says "Bank error" or "Card not accepted", the problem may be on the card issuer's side: make sure the card is not blocked, limits are not exhausted, and Internet banking is available. In the case of Google Pay, it is also worth checking whether the card token has expired.
💡
The most common reason for failure is poor contact or improper positioning of the phone relative to the terminal reader.
In rare cases, you may need to clear the cache of the Google Pay app. Go to Settings → Apps → All Apps → Google Pay → Memory and click Clear Cache. This will not delete your cards, but update the data of the Google Play services.
Payment security via smartphone
Payment by phone is considered more secure than using a plastic card. When transferring data to a terminal, the smartphone does not broadcast the real card number, but uses a one-time cryptographic code, and even if hackers intercept the signal, they will not be able to use this data to re-purchase.
In addition, to conduct a transaction for an amount above a certain limit (usually 1000 rubles) or after several purchases in a row, the system will require biometric authorization. Plastic card with PayPass technology can be paid simply by attaching to the terminal, without entering a pin code, which creates risks in case of loss.
Xiaomi owners are also encouraged to use the “Second Space” or guest mode feature if you give the phone to children or strangers.This will prevent accidental or unsank “one-on” purchases through tied cards.
