In today’s smartphone world, it’s no longer enough to just call or text; devices are becoming digital wallets that hold dozens of bank cards. Xiaomi ecosystem users often wonder what exactly the technology is called, allowing you to pay for purchases with one touch of your phone to the terminal, the answer lies in the bundle of NFC hardware module and software services such as Mi Pay or Google Pay.
Contactless payments are built into most of the brand’s current models, from the Redmi budget series to the flagship Mi and Xiaomi. However, the technology does not guarantee that it will automatically work out of the box without first setting up and binding a bank card. In this article, we will discuss in detail the architecture of payment systems in the shell of MIUI and HyperOS.
Understanding Near Field Communication will help you not only pay for your shopping in supermarkets, but also use electronic passes safely or transfer files quickly. We will look at all the nuances that may arise when you activate the service, and answer the question why the name of the feature may differ in some regions.
Technological basis: what is NFC in Xiaomi smartphones
NFC stands for Near Field Communication, which translates to “near field communication,” and it’s this chip, built into the top of the Xiaomi smartphone body, that provides the physical foundation for contactless transactions, which runs at 13.56 MHz and can communicate up to 10 centimeters.
Unlike Bluetooth or Wi-Fi, NFC technology does not require complex device pairing or password entry. Communication is established instantly when you bring a gadget to a reader (payment terminal). In the context of Xiaomi smartphones, the NFC chip can work in three main modes: card emulation, tag reading and peer-to-peer data exchange.
The card emulation mode is used to make payments, in which your Xiaomi phone pretends to be a plastic bank card with a chip for the terminal, and the security of the process is ensured by the fact that the real card data is not transmitted directly, but a special token is used.
- 📡 Module NFC consumes minimal energy and does not drain the battery if it is simply on in the background.
- 🔒 Data exchange occurs only with physical contact or close proximity, which excludes remote reading by attackers.
- 🏦 Technology is supported by the vast majority of modern POS-terminals around the world.

If you’re not sure if your model has NFC, look at the specs in the About Phone menu or check for the NFC logo on the back of the device.

Main services: Mi Pay, Google Pay and third-party solutions
When we talk about the name of the payment feature, we often confuse the name of the technology (NFC) with the name of the aggregator service. Xiaomi has historically developed several platforms, and the global standard has long been Google Pay (now Google Wallet), which is pre-installed on all certified Android devices.
However, in China and some other regions, the company’s own platform, Mi Pay, is an analogue of Apple Pay, developed by Xiaomi engineers specifically for their devices. Mi Pay allows you to add cards directly to the system application “Security” or “Wallet”, bypassing Google services, this is especially true for users who do not use a Google account or are in regions with limited access to the services of the search giant.
In addition, many banks release their own NFC-enabled applications, such as those of SberBank, Tinkoff, or Revolut, which may have a built-in payment function, in which case the phone acts simply as a data transmitter for a particular banking application that takes over the generation of the token.
It's important to distinguish between these services when you set up, and if you're trying to add a card to Mi Pay and your bank doesn't support it, you're not going to be able to do it, so you're going to have to use Google Wallet or your bank's app, and the list of supported banks for Mi Pay is much narrower than for the Google ecosystem.
Instructions: How to activate and configure contactless payment
The process of setting up the payment function on Xiaomi smartphones is quite linear, but requires careful input. First of all, make sure that the NFC module is activated. To do this, lower the notification curtain from the top of the screen and find the NFC icon. If it is not in quick access, go to Settings → Connection and Sharing → NFC and move the switch to the active position.

A prerequisite for contactless payment is the availability of device protection. PIN-without this, banking applications will refuse to save payment data for security purposes.
⚠️ Note: When adding a card to Mi Pay on Chinese-based devices (CN ROM) It may be difficult to add foreign bank cards due to regional server restrictions.
Comparison of payment methods: Characteristics table
To better understand the differences between the methods available, it is worth considering their comparative characteristics: each method has its advantages and limitations, which can be decisive in choosing the main instrument for payments.
For example, Google Pay provides greater compatibility with international subscription services and apps inside the phone. Mi Pay often gives access to exclusive coupons and discounts in Xiaomi partner stores, especially in Asia. Banking apps can offer more detailed spending statistics directly at the time of payment.
| Characteristics | Google Pay (Wallet) | Mi Pay | Bank's annex |
|---|---|---|---|
| Bank compatibility | Very high (globally) | Medium (depending on region) | Depends on the specific bank. |
| Integration with OS | Deep (systemic) | Deep (systemic) | Surface (third-party) |
| Working without the Internet | Yeah (offline tokens) | Yes. | Partially (required for some tokens) |
| Security of data | High (tokenization) | High (tokenization) | High (depends on the bank) |
The choice of the method depends on your habits and geography of residence. If you travel often, Google Wallet will be the most versatile solution. For Chinese residents or users who are deeply integrated into the Xiaomi Home ecosystem, Mi Pay may be preferable.
