Modern wearables have long ceased to be just pedometers, becoming full-fledged tools for interaction with the world. Xiaomi Mi Band 6 became one of the first fitness bracelets in the budget segment, received the NFC module, which allowed users to forget about finding keys and plastic cards at the most inopportune time. However, owners often face confusion when buying, since the device comes in two versions: conventional and NFC, which are almost identical in appearance, but functionally different.
The process of setting up contactless payment and access control requires care, especially if you plan to use the bracelet as an office pass or intercom key. The Chinese version of the device may differ from Global by the presence of pre-installed payment systems such as Alipay, but the basic principle of the communication module remains the same for all regions. NFC-The tags depend not only on the tracker itself, but also on the software installed on your smartphone.
In this article, we will discuss in detail the algorithm of actions necessary to activate the communication module, add maps and solve typical synchronization problems. You will learn how to turn your gadget into a universal tool that allows you to pass the subway turnstiles or pay for coffee with one touch of the wrist.
Verification of compatibility and device version
The first and most critical step is the physical presence of a communication module on your device, and many users mistakenly believe that the function can be activated software on any model, but this is not the case. NFC-The chip is built only into a special modification of the bracelet, and if you purchased the basic version, no manipulation of the software will not make it work in the mode of emulation of cards.
To make sure you have a module, carefully inspect the back of the tracker capsule. The contactless version, next to the charging contacts, usually has the NFC label. You can also tell the difference by packaging: the box with the supported model always has the appropriate logo or marking. If you buy the device from hand or from a small store, be sure to check these parts before paying.
Global versions often have limited functionality of payment systems compared to Chinese counterparts, where Alipay and WeChat Pay are integrated. For users from Russia and CIS countries, the most relevant possibility is the emulation of access cards and transport cards that work at the hardware identifier level.
⚠️ Warning: Do not attempt to open the bracelet body yourself in search of an antenna. This is guaranteed to lead to loss of warranty and violation of the tightness of the device, which has a high class of water protection.
Smartphone compatibility also plays a major role. To work properly, the phone's operating system needs to support the necessary data protocols. Usually Android 5.0 and higher or iOS 10.0 and higher. Make sure your phone also has an NFC module activated, although it is not always required to set up the bracelet initially, but you may need to copy access cards.
Installation and configuration of the Mi Fitness application
For the sixth generation and newer models, Xiaomi has switched to the Mi Fitness platform (formerly known as Zepp Life), although support for the old Mi Fit app is still maintained for some regions.
Download the application should be exclusively from official stores: Google Play for Android or App Store for iOS. Using third-party builds or modified versions can lead to unstable operation of the communication module or leakage of personal data. After installation, you need to register a Xiaomi Account or log in through an existing profile.
The process of pairing is as follows:
- 📱 Turn on Bluetooth on your smartphone and bring the bracelet to your phone.
- 📲 Launch the application and click the button "Add device».
- ⌚ Select Mi Band 6 from the list of found gadgets.
- ✅ Confirm pairing by clicking on the tick on the bracelet screen.
Once successfully connected, the app will offer to update the bracelet firmware, which is a must-do step, as newer versions of firmware often fix bugs. NFC-The update process can take several minutes, while holding the bracelet next to the phone and do not turn off the smartphone screen.
☑️ Preparation for setup NFC
Activation of NFC and Adding Access Cards
The non-contact module is primarily focused on emulating access cards, which allows you to use the bracelet as a key to an intercom, office turnstile or gateway. It is important to understand that the technology works at 13.56 MHz, so old-style cards with a frequency of 125 kHz will not be copied.
To add a map, follow the following steps in the appendix:
- Go to the device profile and find the Profile or Additional section.
- Select the Access Card (Access Card) option.
- Click on “Add Card” and follow the instructions on the screen.
- Attach a plastic card to the back of your smartphone (if the phone can read cards) or choose manual input if such an option is available in your area.
In some cases, the app may suggest creating an "empty card" mode, which is useful if automatic reading is not possible. The bracelet generates a unique identifier, which you then need to register with your building's access control system. To do this, contact the administrator or management company with a request to “prescribe” a new one. ID-code.
⚠️ Note: Some access cards have additional protection or encryption, in such cases, simple copying is not possible, and you will need to create an empty card with subsequent manual binding. ID-security-room.
The success of the copy depends on the type of chip in the original card. Standard Mifare Classic cards are copied most often without problems. If the process is unsuccessful, try bringing the card closer to the center of the bracelet or removing the protective case from the smartphone if the reading is through it.
Using a bracelet to pay for purchases
The possibility of paying for purchases through Xiaomi Mi Band 6 is implemented through the service Alipay.This method does not require the Internet on the wristband at the time of purchase, as it uses an offline code or card binding within the Alipay ecosystem.
To set up payment, it is necessary:
- 💳 Download the Alipay app and register an account.
- 🔗 In the Mi Fitness app, find the “Payment” or “Alipay” section».
- 📲 Scan. QR-code displayed on the bracelet screen via the Alipay app.
- 💰 Linking a bank card to an Alipay account.
After binding for payment, it is enough to display the bracelet on the screen QR-The terminal reads the code and the amount is debited from the linked account., the conversion rate and fees depend on the rules of the payment system and your bank.
For users from Russia, this method can be inconvenient due to the complexity of depositing and linking cards. NFC-The payment system market is dynamic, and support for new methods may appear in future software updates.
Why is the payment not working in my area?
Transport cards and other NFC functions
One of the most useful features is the use of the bracelet as a transport card, which in some cities in China, as well as in some regions in other countries, can emulate the transport cards of local operators, which allows you to pass through the turnstiles of the subway and buses, simply by holding your wrist to the reader.
Adding a transport card is done through the Transport Card section of the app, you will be asked to select the city and type of map, after selecting the system will create a virtual copy of the map, to replenish the balance usually requires the use of the original application of the transport operator or specialized services, as a direct replenishment interface in Mi Fitness may not be available.
Comparison of the capabilities of different types of cards:
| Type of card | Method of addition | The Necessity of the Internet | Region of work |
|---|---|---|---|
| Access card (Domophone) | Copying / Manual ID entry | Just for the setup. | Globally |
| Alipay (Payment) | Tie-in through QR-code | Required for code generation | Globally (service China) |
| Transport map | Creating a virtual map | Required for replenishment | Locally (China et al.) |
| Smart Home (Mi Home) | Automation of scenarios | Required for customization | Globally |
You can also use the module to automate scenarios in a smart home system, such as tapping a specific tag with a bracelet can turn on a light in a room or trigger a "I'm at home" script. NFC-tags or bracelet itself (depending on configuration).
💡
Use the Empty Card function to create a universal key, write down the card's ID in a notebook or save a screenshot so that if the bracelet settings are reset, you don't have to contact the management company again to register the device.
Solution and troubleshooting
Despite the smoothness of the process, users may encounter difficulties. Often the bracelet does not see the card or the copying process is interrupted in the middle. First of all, make sure that the card does not have metal protection or a thickened case that shields the signal. Also check if the antenna inside the plastic card is damaged.
If the bracelet has stopped responding to commands, try rebooting. To do this, find System → Reboot in the device menu or press the touch button for a few seconds. In rare cases, a full reset to factory settings helps, but before that, make sure to back up the data in the application.
Problems can also arise on the app side. Make sure the Mi Fitness app has all the necessary permissions, especially access to Bluetooth, geolocation and background work. Without geolocation permission, Android smartphones often block scanning. NFC-safety devices.
⚠️ Note: If the card is not copied after multiple attempts, it may be a high level of protection or a non-standard format, in which case the use of the bracelet as the key to this card is technically impossible without special equipment.
The stability of the module also depends on the battery charge. At a low charge level (less than 10%), the system can automatically turn off energy-intensive functions, including NFC, to extend the time of the tracker.
💡
Successful NFC configuration depends on three factors: compatibility of the bracelet version, card type (13.56 MHz) and correctness of the permission settings in the application on the smartphone.
