The modern smartphone has long since ceased to be just a means of communication, turning into a digital wallet that is always at hand. Owners of Xiaomi and Redmi devices often wonder how to activate contactless payment function so as not to carry plastic cards. NFC (Near Field Communication) technology allows you to transfer encrypted payment data to the terminal with a simple touch, which greatly speeds up the purchase process in the store.
However, despite the popularity of the feature, not all users are aware of the nuances of its operation in the current limitations and technical features of the operating system MIUI or HyperOS. It is important to understand that standard support for Google Pay cards of Russian banks is currently limited, but there are alternative methods and settings that allow you to use the potential of your gadget as efficiently as possible. In this article, we will discuss the technical aspects of the module’s inclusion, checking its operability and current methods of making payments.
Before you start setting up, make sure your device is physically equipped with the appropriate communication module. Most modern Xiaomi mid- and flagship models have an embedded chip, but in budget versions this component may be missing to reduce cost. Hardware is the first and most important step, without which software manipulation will be useless.
Checking for the presence of NFC module on the device
The first thing to do is to visually inspect the case of a smartphone or see the specifications on the box. Usually, the NFC logo is applied to the back of the device or indicated in the specification under the acronym "Near Field Communication." If there is no marking, this does not always mean that there is no function, since manufacturers sometimes save space on the design of the package.
A more reliable way is to check your system settings. Go to Settings → Connection and Sharing. There should be a switch or a separate menu item with the name of the technology. If you don't find this section, search by settings by typing the corresponding query into the search bar.
- 📱 Open the "Security" or "Services and Feedback" app on your desktop.
- 🔍 In the search bar, enter the word"NFC" See if the result of the transition to the settings will appear.
- 🛠️ Use third-party diagnostic apps from the Play Market store to accurately identify components.
⚠️ Note: If there is no mention of a module in the settings search or in the model characteristics list on the official website, it is not possible to activate it software.
You can also use the engineering menu for deep diagnostics. Dial ##6484## in the phone app. In the test menu that opens, select "NFC test." If the system gives an error or items are not listed, then the chip is missing or defective.
Basic activation and configuration of the module
Once the module is confirmed, you need to configure it correctly to ensure the security of transactions, turn the switch on in the settings menu, after which the system can request confirmation or suggest choosing the default payment application, which is often the reason for conflicts when the phone tries to open the inappropriate application when it reaches the terminal.
In Settings → Connection and Sharing → NFC, look at the “Anitron Location” item. In some Xiaomi models, the antenna is located at the top of the body, in others, in the center or near the camera, and knowing this will help you find the reader faster in the terminal.
☑️ Security setting NFC
A critical security element is screen locking; payment systems must have secure authentication; a simple swipe to unlock will not be enough, requiring a digital code, a pattern lock, or biometric security.
| Setup parameter | Recommended value | Safety impact |
|---|---|---|
| Screen locking | PIN code/Print | High (required) |
| Confirmation of payment | Always ask | Medium (protection against accidental write-offs) |
| Android Beam | Off. | Low (function is outdated) |
⚠️ Note: Do not use simple passwords like "1234" or "0000" in the event of a phone theft, this will allow attackers to unlock the device and potentially access the associated cards unless additional verification is configured.
Once the module is enabled, the phone may suggest installing or updating a payment app. Android will determine the priority app itself. Make sure that the one you plan to make purchases through, such as Google Wallet or your bank app, is selected.
Installation and binding of bank cards
The process of adding a card begins with downloading the official application of your bank or using the Google Wallet aggregator (formerly Google Pay).For Visa and Mastercard cards issued by Russian banks, direct payment through Google Pay is currently not working due to sanctions restrictions, but MIR cards and cards of foreign banks are functioning normally.
To add a card, open the Google Wallet app and click the Add to Phone button. The smartphone camera automatically reads the data from the plastic, or you can enter it manually. The bank will necessarily conduct the verification procedure by sending an SMS code or requesting confirmation through the bank's mobile application.
- 💳 Scan the card or enter a number, expiration date and CVV-manually.
- 📲 Accept the terms of the agreement with the payment system and the issuing bank.
- ✅ Confirm ownership of the card through the code from SMS or push notification.
Why can the bank refuse to be tied?
It is important to note that tokenization (the process of replacing real card data with a digital token) requires a stable Internet connection at the time of the binding, and once successful tokenization is used for payment in the store, the Internet will no longer be needed, since a secure NFC communication channel is used.
If you use a MIR card, make sure that the bank app supports Mir Pay or similar services available in the RU Store.The principle of operation remains the same, but the authorization servers are located in the country, which guarantees the stability of the service.
Alternative payment methods and Mi Pay
Xiaomi device owners have access to the MIUI branded shell, which includes its own Mi Pay service, which allows you to pay for purchases with MIR cards even when Google Pay does not support the issuer, but Mi Pay support depends on the specific bank and region of the smartphone.
To check the availability of Mi Pay, open the Mi Credit or Wallet app that is pre-installed on your smartphone. If your bank is working with Xiaomi, you will see the option of adding a card to this service, which is a great backup for users who need maximum compatibility.
⚠️ Note: Mi Pay only works on smartphones with global or Russian firmware (CN ROM) This service may not be available or work properly without flashing.
There are also aggregator apps like Mir Pay or SberPay that emulate card performance via NFC, which create a virtual map image that is read by the terminal, and they need to install an app from the official RuStore store or the bank's website, as they may not be available on Google Play.
💡
Use the widgets of banking applications on the desktop for quick access to the QR-switching between cards or codes if NFC currently unavailable.
Solving typical payment problems
Often, users are faced with a situation where the terminal does not see the phone despite the module being turned on, and one of the most common reasons is a thick case or a metal plate on the back that screens the signal, and the metal blocks the electromagnetic field necessary for data transmission.
Another common problem is a malfunction of Google Play Services, which is a system component that is responsible for the security of transactions, and it causes payment errors, and the solution is to clear the cache or update the component.
To correct payment errors, a simple reboot often helps. NFC-module: turn it off and turn it on in the notification curtain, then restart the smartphone.
If payment fails, check the list of applications with access to NFC. Possibly the conflicting application intercepts the signal. Go to Settings → Apps → All Apps → Special Access → Use NFC and make sure that access is only available to payment systems.
