Contactless payment on Xiaomi: setting up and using

Smartphones are no longer just a means of communication, becoming a universal tool for solving everyday tasks, including financial transactions. Owners of Xiaomi devices often wonder how to contactlessly pay from their phone so as not to carry physical cards and wallets. NFC (Near Field Communication) technology allows you to transfer data over short distances, providing a safe and fast transaction process in any retail outlets equipped with the appropriate terminals.

Implementation of this function on shell devices MIUI or HyperOS requires careful consideration of security settings and software choices, and depending on the region of sale of the smartphone and the version of the operating system, the methods can vary from native Google services to specialized applications from banks. NFC-The module will help to avoid mistakes when trying to make a purchase in a supermarket or cafe.

In this article, we will discuss in detail all the available ways to activate the function, the algorithms for adding bank cards and methods for circumventing possible restrictions. You will learn which models support emulation, how to check the status of the chip and what to do if the terminal does not read the device.

Compatibility check and activation of NFC

The first step before setting up any payment services is to convince you that you have the necessary hardware. Not all Xiaomi budget models are equipped with a short-range communication module, so it is important to know exactly the specification of your gadget. Usually, information about the presence of NFC is contained in the technical documentation or on the official website of the manufacturer in the characteristics section of a particular model.

You can use system settings to check quickly, go to the settings menu, select About Phone or Specification, and find a line describing wireless interfaces. If it says NFC, the hardware is there and ready to go. The absence of a mention indicates that software activation is impossible without replacing the motherboard, which is not economically feasible.

Once the module is confirmed, you need to activate it softwarely. Most often, the switch is in the notification curtain, but it can also be found in deep system settings. Go to Settings → Connection and Sharing → NFC and put the slider in an active position. Without this step, no application will be able to interact with external readers.

It is also important to pay attention to the location of the antenna. In most Xiaomi smartphones, it is built into the top of the back cover or in the main camera unit. When you move to the terminal, try to navigate this area, as in other parts of the case, the signal may be too weak to conduct a transaction.

⚠️ Attention: If, after activation, NFC In the notification curtain, the icon doesn't appear or disappears immediately, maybe the problem is a software failure or damage to the antenna plume. Try restarting the device or resetting the network settings.

Google Pay and Alternative Services

The traditional payment method on Android devices is Google Pay (now known as Google Wallet), but under sanctions restrictions, the functionality may be limited to cards issued by Russian banks. For users with foreign bank cards, the process remains standard: you need to add a card to the Google Wallet app, confirming it through the Google Wallet. SMS-issuer.

For cardholders in Russia, the situation is different: direct binding to Google Pay does not work, so you have to look for workarounds or use alternative solutions. Some users successfully use virtual cards of foreign payment systems, if they have the opportunity to replenish them. QR-codes through bank applications, although this is no longer a contactless payment through the NFC purely.

If your bank supports Mir Pay technology or its own payment systems, the setup process will be similar: download the official bank application from a trusted source (RuStore or bank website), log into your account and follow the instructions for issuing a virtual card or tokenizing an existing one, and then in the NFC settings, you will need to choose this application as the main means of payment.

Remember that any payment system requires a stable Internet connection when you add the card, although the terminal may not need the Internet to conduct the transaction itself (tokens are stored in secure memory).

Use of the Mi Pay application and its features

Xiaomi was developing its own payment system called Mi Pay, which was supposed to be a native alternative to Google’s solutions, but in the global market, and especially in Russia, this service has not received widespread support from large banking institutions.

However, in some regions of Asia, Mi Pay continues to function and is integrated directly into the system application "Security" or "Wallet". If you are a user of the Chinese version of firmware, you may have the option of adding transport cards or loyalty cards, but support for bank cards. Visa/Mastercard/Mir It also depends on local partnerships.

The main difficulty is that even with the Mi Pay menu item, the lack of agreements with banks makes it useless for financial transactions, so experts recommend not to waste time looking for hidden Mi Pay settings, but to focus on current banking applications that are regularly updated and adapted to changes in the legislation.

It is worth noting that having the Mi Pay logo on a smartphone box does not guarantee that it will work in your region, but it is a marketing element that indicates technical capability, but not the actual availability of the service.

Adding a card to the banking application

The most relevant method of contactless payment today is the use of native applications of banks themselves, the largest financial institutions have implemented NFC support directly into their mobile customers, which allows you to bypass the restrictions of third-party payment systems, the process of adding a card in such cases is as simple and automated as possible.

To start with, make sure you have an official bank application installed. If you use an Android device, download the software only from trusted stores such as RuStore, AppGallery or directly from the credit institution's website. Avoid installing modified versions from unverified sources, as this jeopardizes the security of your financial data.

When you log in to your account, find the section that's associated with your payment or card settings, usually called "Play by phone," "Pay," or has an appropriate icon. NFC-You'll need to enter the module and ask for a map. CVC-code and confirm the action through SMS. After successful tokenization, the card will appear in the list of available means of payment.

An important condition is to install the bank application as the default payment method. Go to the NFC settings and select the banking application you want from the "Pay without contact" option, and now it will be launched when you unlock your phone and bring it to the terminal.

Below is a table showing support for different payment methods depending on the type of card and application:

⚠️ Note: When adding a card to the bank's application, make sure that the phone does not have superuser (Root) rights.The presence of root rights can be considered a threat by the bank's security system, and the payment function will be blocked.

Payment problems and how to solve them

Even when properly configured, users can experience situations where the terminal is not reading the phone. One of the most common reasons is a thick case or the presence of metal elements on the back of the device. The metal shields the NFC signal, making it impossible to exchange data. Remove the case and try to repeat the operation.

Another common problem is mispositioning: Terminals have different readout zones, and sometimes you need to slowly drive the top of the phone along the surface of the terminal to catch the signal.Don't put the phone too sharply, hold it still for 1-2 seconds after the vibration appears.

If payment fails, check to see if the limit on contactless payments has been exhausted without entering a PIN, and for security reasons, banks limit the amount or number of such transactions, in which case the terminal will request a pin from the card, and the operation will need to be completed in the standard way.

Also, make sure the phone screen is unlocked. For security reasons, most payment systems don't transact if the device is in sleep mode. A quick double tap on the power button or using a fingerprint scanner will help to quickly activate the screen.

💡

If payment fails, try turning off and re-enable flight mode (air mode) this will restart all radios, including NFC, and may fix a temporary software communication failure.

Security issues in the use of NFC

Security of financial transactions is always the first priority, NFC technology itself has a high level of protection, since the range is only a few centimeters, which excludes remote reading of data by malicious users, and when paying through the phone, the card number is not transmitted, but a unique one-time token is used.

But there are risks, and the main one is the loss of an unlocked phone, and if you don't have a pin, a pattern lock, or biometric security, anyone who finds a device can make a purchase, and make sure you set up a mandatory authorization for each payment, or require that the device be unlocked before you make a transaction.

NFC also recommends disabling Android Beam if you don't use it to transfer files, a protocol that can theoretically be used for attacks, although it's already being abolished or replaced with Quick Exchange in modern Android versions.

Regularly update the operating system and applications of banks. Developers constantly close vulnerabilities through which hackers could access payment tokens. Using an outdated version of Android with known security holes is strongly discouraged for financial transactions.

💡

NFC-Payment is safer than using a physical plastic card, since card data is not transmitted directly, and the device screen must be unlocked to confirm the transaction.
