Xiaomi fitness bracelet owners often wonder about the functionality of the NFC module in the Band 4. Unlike the global version, the NFC option allows you to use the device for contactless payment in stores, transport and other points of payment, which turns a simple activity tracker into a full-fledged payment tool tied to the wrist.
Despite the technology, however, the list of supported financial institutions in Russia has its own peculiarities: Many users mistakenly believe that the function requires an official application of a particular bank. In fact, the setup process takes place through the Xiaomi Pay or AliPay ecosystem, and support depends on the type of payment system to which your card is attached. In 2021, the payment infrastructure has become more flexible, but requires a careful approach to choosing a “donor card”.
In this guide, we will discuss in detail which banks and cards are compatible with Mi Band 4 NFC. We will not list the banks that are "supported", since technically it depends not on the bank, but on the payment system. You will learn how to properly link a Visa, Mastercard or Mir card, what fees can arise and how to avoid common errors in data synchronization.
The principle of NFC in Xiaomi fitness bracelets
The NFC (Near Field Communication) technology in the Mi Band 4 bracelet works on the principle of emulating a card. The device does not store money by itself; it only transmits an encrypted token to the terminal payment system. Xiaomi Pay technology, which is based on payment system security standards, is used for work in Russia. It is important to understand that the bracelet acts as a digital key, not an electronic wallet.
In 2021, the bracelet’s division into UnionPay, Mir, Visa and Mastercard payment systems became relevant. Since it does not have direct integration with Apple Pay or Google Pay, it uses its own security profile, which means that for successful payment, the card must be issued by a bank that allows data tokenization through third-party applications or specialized intermediary services.
⚠️ Attention: Mi Band 4 bracelet NFC It does not support adding cards through the Google Pay or Samsung Pay app. customization is possible only through the Mi Fit app (now Zepp Life) or Xiaomi Wear.
If you plan to use your device in Russia but your Mi Account is registered in Europe or China, the list of available transport cards and payment profiles may vary. For Russian residents, it is recommended to use the Russia or China region (with caution) to access full functionality.
List of compatible banks and payment systems
The question of which banks Xiaomi Band 4 NFC supports often puzzles users, as there is no official list of "partners", support depends on whether the bank allows to issue virtual cards or cards of the payment system Mir and UnionPay, which can be linked to the service Xiaomi Pay. In 2021, the most stable cards that emulate the standards of international systems.
In practice, for use in Russia, cards of the following issuers that successfully pass tokenization are most often recommended:
- 🏦 Sberbank - cards of the Mir system and Visa/Mastercard (limit-bound).
- 💳 Tinkoff – any debit cards that support contactless payment.
- 🚀 Yandex.Money (now YuMoney) – plastic cards with support NFC.
- 🌐 Raiffeisenbank – Mastercard and Visa cards.
It is worth noting that Mir cards have priority in working with Russian terminals through the Xiaomi Pay profile. UnionPay cards are also supported, but their use depends on the specific terminal at the point of sale. If your bank does not appear in the list when trying to automatically set up, this does not mean that it does not work. Often manual binding through the AliPay service or adding as a "Transport Card" is required.
⚠️ Note: Maps issued after sanctions were imposed 2022 Visa and Mastercard systems may not be supported at the level of emulation in foreign services. 2021-2022 Priority of the Mir Cards.
Credit cards can also be tied, but banks can block such transactions for security reasons, requiring additional confirmation via SMS or push notification.
How to link the card to Mi Band 4 NFC
The process of setting up payment for Mi Band 4 requires sequential steps. Before you start, make sure that the bracelet has the latest firmware version installed, and the Mi Fit (or Zepp Life) application is updated to the current version, Bluetooth and Internet access should also be enabled on the smartphone.
Follow a step-by-step algorithm to activate the function:
☑️ Payment settings for Xiaomi Band 4
Once you click the add button, the system will suggest you to choose a region. It is critical for users from Russia to choose the right region, because the list of available transport cards and payment profiles depends on it. If you choose Russia, you will be available to Xiaomi Pay. If China is in Chinese or English, and the functionality is sharpened for local cards.
When entering map data (CVV-code, expiration date, number) make sure you enter correctly, the system will verify with the issuing bank, if the bank requires confirmation, your phone will come to your phone. SMS Or a notification from a banking application, and after a successful check, the data will be encrypted and transmitted to the bracelet chip.
💡
Before linking the main card, try adding a minimum (residual) card or a virtual card to test the NFC performance without risking fixed assets.
The process of writing data to the chip takes from 30 seconds to 2 minutes, while keeping the bracelet in close proximity to the smartphone (no more than 10 cm) and do not switch between applications. Interrupting the process can lead to a recording error, and the procedure will have to start again.
Configure through AliPay service
An alternative but less convenient payment method is to use AliPay.This method is often used if direct binding through Xiaomi Pay is not going through or if you are in a region where Xiaomi Pay is restricted. QR-code or code generation on the terminal screen, although the Mi Band 4 bracelet itself does not have a screen to display the code, it can store the token for authorization.
However, for Russia, the emulation of the card is more relevant, and if you decide to use the AliPay profile, you need to:
- Download the Alipay app and register an account.
- Link the card in the Alipay app.
- In the Mi Fit app, select adding a card via AliPay.
- Sign in to your account.
It is important to understand the difference: AliPay on the bracelet is more a tool for traveling in China or using it in specific partner stores. For everyday payment in supermarkets near the house through the terminal "touch and pay" prefers a profile Xiaomi Pay with a Mir or Visa/MC card binding.
Why can AliPay not work in Russia?
