Modern wearables have long since ceased to be just pedometers, becoming full-fledged tools for a comfortable life. One of the most popular features for owners of Xiaomi Mi Band 5 is the ability to contactlessly pay for purchases. This eliminates the need to carry a wallet or get a smartphone in line at the checkout. However, the process of setting up this option has its own nuances that often confuse users.
To pay with the touch of the wrist, you need to understand that the NFC technology in this device works differently than in smartphones with Google Pay. It uses memory card emulation, which requires a specific approach to configuration. In this article, we will discuss in detail all the stages of preparation, installation of the necessary applications and direct transaction.
It is important to note that for the full function you will need a version of the bracelet with NFC module. Global versions without this chip do not support adding cards. If you are planning to buy or already have the desired modification, carefully follow the further instructions for the correct configuration of the payment profile.
NFC Features in Mi Band 5
Xiaomi’s fifth-generation NFC fitness tracker is implemented through card emulation technology, which means that the bracelet does not store money in its account and has no direct access to bank accounts via the Internet. Instead, it simulates a physical plastic card by reading data from the chip and transmitting it to the terminal, which is why pre-associating the card through the app is a must.
Unlike smartphones, where card data is encrypted and tokenized by cloud services, it uses a simpler but more reliable method of writing data to virtual media, which imposes certain restrictions on the number of cards and types of payment systems supported.
⚠️ Note: The bracelet does not support direct connection to Apple Pay or Google Pay. You can not simply “tie” a card from these services; you need to use a special plugin to emulate a card of the World.
It is also worth considering that to work NFC module must be activated and battery power does not have to be critically low. Although the technology is optimized, frequent use of payments can slightly accelerate the discharge of the device, however, for most users this factor remains invisible in everyday use.
Device preparation and application selection
The first step towards contactless payments will be to install the right software; the official Mi Fit app (or Zepp Life, since the services have been combined) is the basis for managing the tracker; however, the standard functionality of the app is not enough to add transport cards or payment cards in the Russian segment.
You will need to find and install a special plugin, often called “Mi Band 5 NFC” or “Plugin for Mi Band”, which can be found in official app stores such as Google Play or the App Store, or through third-party resources if direct access is limited in your region.
The firmware update process is best done in advance by connecting the bracelet to the charger and providing a stable connection to the Internet, ensuring that all modules, including NFC, will work correctly. Older versions of the software may not contain the necessary drivers for new banking plugins.

Before you start setting up, back up your data in the Mi Fit application, which will allow you to quickly restore the settings in case of a failure when installing plugins.
Instructions for adding a map of the World
The process of activating the payment function begins inside the plugin you installed in the previous step. Open the application and find the section responsible for the cards. The interface may vary slightly depending on the version of the plugin, but the logic of actions remains the same for all users.
From the menu, select the option to add a new card. The system will prompt you to choose the type of card — in this case we are interested in "Bank card" or "MIR card." After choosing the type, you will need to enter your plastic media. CVC-reverse-code.
☑️ Algorithm for adding a map
Once you enter the data, the system will contact the issuing bank for verification, and your phone will receive an SMS message with a confirmation code that you need to enter into the appropriate field, which is critical because it confirms your right to dispose of funds in the account.
When the verification is successful, the card profile will start to be loaded into the memory of the bracelet, while holding the device next to the phone and do not close the application, and when you complete the download, the notification will appear on the tracker screen, and the card status will change to Active.
The payment process in the store
Once you've set up successfully, you can start using the bracelet to calculate. When you go to the cashier, tell the cashier that you'll pay with the card. When the terminal is ready to read, hold your wrist and bracelet to the signal reception area.
The device will automatically turn on NFC-It's going to transmit data. It usually takes 1 to 3 seconds to read, and visually, it's going to vibrate the bracelet and it's going to show up on the screen. If the purchase amount exceeds the limit for payment without a pin code (usually 1000 rubles), the terminal can request the PIN code input, which will have to be entered on the terminal itself, since there is no keyboard on the bracelet.
| Parameter | Meaning/Description |
|---|---|
| Range of action | Up to 5-10 cm (depending on the terminal) |
| Response time | 1-3 seconds |
| Limit without pin code | Determined by the bank (standard 1000 rubles) |
| Number of cards | Usually up to 5-8 cards in memory |
All the data is already written into the chip, but if you block the card through a bank application, the bracelet will not know about it until the moment you try to pay, and the terminal will give a refusal.
Map management and security
The Xiaomi Mi Band 5 plugin allows you not only to add, delete, and switch between cards, which is convenient if you use multiple cards from different banks to get cashback in different spending categories.
In the app, you can see the list of attached cards and select the main one, which will be activated by default when you reach the terminal. If you lose the bracelet, the first thing you need to do is block the cards through the bank app or by phone on the hotline. The bracelet itself can be reset to factory settings, but this will not delete the data from the card instantly, so locking from the bank is mandatory.
⚠️ Note: Do not store cards with a high spending limit on the bracelet without additional protection. In the event of loss of the device, an attacker can make purchases within the limit without a pin code.
Also, consider that some banking applications may require periodic token updates. If the bracelet has stopped responding to the terminal, try removing the card from the profile in the application and adding it again, which often solves problems with the “hang” of the payment profile.
Addressing common problems
Despite the technology, users may face difficulties, and one of the common problems is that the terminal is unable to read the bracelet, which may be due to a too thick sleeve of clothing, a case on the bracelet with metal elements, or simply the wrong angle of application.
Another common cause of failure is time or error in the plugin. In such cases, it helps to reboot the tracker itself (via the Settings menu → System → Reboot) or reinstall the plugin on the smartphone. Also make sure that the phone settings for the Mi Fit application and the NFC plugin allow constant use of geolocation and background work.
What if the bracelet vibrates, but the payment does not pass?
If you've changed your smartphone, remember to untie the bracelet in your old device and re-enter the new one. Card binding is often tied to a particular account and device, so simply re-attaching Bluetooth may not be enough to restore payment features.
💡
Stability of work NFC-Payment depends on the version of the plugin and the relevance of the bracelet firmware.
