The back of the original device should be labeled NFC, and often comes with a special sticker with the logo of the payment system.

The next step is to install the right software on your smartphone.

Choice of payment method: Mi Pay or third-party services

There are several ways to implement contactless payments through wearables on the market: the official Mi Pay method in Russia and many other countries does not work directly with local banks due to the lack of partnership agreements, so users have to resort to emulation cards or using intermediary services.

The most popular solution is to use the Mi Band Tools app or similar utilities that allow you to download card data to the memory of the bracelet, bypassing official restrictions, a method that requires care, since you are actually creating a digital clone of your plastic card, and services like Payment Cards that generate virtual cards for wearable devices can be an alternative.

⚠️ Note: Using third-party card emulation applications carries potential security risks.You share your payment method data with third parties, so it is recommended to use a separate card with a limited limit for this purpose.

Also worth considering is virtual cards from payment systems that support tokenization, with some banks issuing special cards for wearable devices that can be added through their own apps as long as they are compatible with Xiaomi protocols.

Instructions for adding a map through Mi Band Tools

The most common way to implement payment is to use a bundle of Mi Fit app and Mi Band Tools (or PayTool) utility, which allows you to download card data directly into the bracelet chip, and you first need to break the bracelet connection to the main Mi Fit app to free the Bluetooth module to work with the setup tool.

Run the payment settings app and follow the instructions on the screen. You will need to take a picture of the front and back of the card, and enter the card. CVC-The application will encrypt the data and transmit it to the device. 2-3 minutes during which the bracelet should be in close proximity to the smartphone.

Once the data is successfully downloaded, a new item will appear in the bracelet menu, "Payment" or "Cards", and now, when you bring your wrist to the terminal, the device will emulate the plastic card.

• 💳 The application will automatically determine the type of card (Visa/Mastercard/Mir).
• 🔒 Data is stored in a secure memory region of the chip NFC.
• 📡 No phone connection is required to pay, works autonomously.
• ⚙️ To remove the card, you need to use the tool application again.

If the process is interrupted in the middle, don't panic. Just remove the unfinished map profile from the app and start the add-on procedure again, the main thing is to ensure a stable Bluetooth connection at the time of data transfer.

Limit setting and payment security

Since the bracelet does not require a PIN code for your payments (usually up to 1000-3000 rubles depending on the bank and country), the risk of losing funds if the device is lost is real.

Many banks allow real-time locking of a card or changing limits through a mobile application. Train yourself to check the status of the card after each purchase. If you lose the bracelet, the first thing you do is block the attached card through an online bank, since it is impossible to find the lost gadget through GPS due to the lack of your own geolocation module.

💡

The bracelet does not ask for a code when paying, so controlling limits in the banking application is your main protection against theft of funds.

You should also pay attention to the "Screen Lock" feature in the Mi Fit app itself, although it does not block it. NFC-The module directly prevents access to step history and other personal information if the bracelet falls into the wrong hands.

Solving Common Problems When Paying

Often, users are faced with a situation where the terminal does not see the bracelet. In most cases, the problem lies in the wrong positioning. NFC-The antenna in Mi Band 4 is at the top of the capsule, closer to the strap.

Another reason could be a metal case or a case if you try to adjust the card by holding the phone nearby, and some banking terminals do not read the low-power signals that the bracelet generates, in which case a tighter pressing or changing the angle of the wrist helps.

⚠️ Warning: If the bracelet stopped responding after the firmware update, it may be that the payment profile has been damaged.

Sometimes the problem is the type of card itself, and 3D-Secure cards or some banks' corporate cards may not be supported by emulation protocol, so try issuing a virtual card from another bank that is loyal to the payment system.

• 📍 Apply the top of the bracelet to the terminal.
• 📵 Keep your phone away during payment to avoid interference.
• 🏦 Check if your bank supports payment through wearable devices.
• 🔋 Watch the charge at low levels. NFC may be off.

If neither method works, try to completely reset the bracelet to factory settings and reconfigure it, which will eliminate software conflicts in the device's memory.
