Question of availability NFC-The module in the popular fitness tracker Xiaomi Mi Band 4 remains one of the most talked about among gadget owners. Users often confuse the various modifications of the device, believing that the standard version is able to support contactless payments. This misconception has generated a lot of controversy on forums and social media, where people share conflicting data about the functionality of the wristband.
In fact, the situation with Near Field Communication in the fourth generation of trackers from Huami and Xiaomi is ambiguous and depends on the specific revision of the device. It is important to understand that the presence of a chip does not guarantee its operation in your region or with your bank cards. Technical specifications often change depending on the market, which creates confusion for the end user.
In this article, we will take a closer look at which versions of the Mi Band 4 actually feature a communication module, how to check for the feature, and why the global version is not available, and how to use the technology in this device and whether to rely on it as a full-fledged payment tool.
Differences between the Chinese and Global Versions
The first thing to know when buying or analyzing features is a clear division into markets. The Global Version, which is mass-produced in Europe, CIS countries and the United States, has no built-in version. NFC-This is done by the manufacturer to reduce the cost of the device, because the payment infrastructure varies greatly from country to country.
At the same time, the Chinese version (CN Version) came in two versions: with and without NFC, and it was the presence of the module in the Chinese revision that gave rise to the myth of universal support for the technology. Visually, these devices are almost identical, but the internal stuffing and firmware have critical differences that affect functionality.
Users often try to stream the global version into Chinese in the hope of activating the payment, but this will not lead to the emergence of NFC, since the physical communication module is simply absent from the global tracker board.
How to check for NFC in Mi Band 4
There are several ways to determine if your tracker is equipped with the right module without disassembling the device. The easiest method is to visually inspect the package. The Chinese version with technology always has the appropriate logo or NFC Edition label on the box. If there are no such markings, you probably have the regular version.
The second is software. When paired with Mi Fit (or Zepp Life), the menu of the device displays the available features. If the card or payment option is not included in the settings list, the module is not active or absent. You can also try adding a card to the wristband menu: if the system writes about an error or a gray item, there is no function.
Technical enthusiasts use special utilities to scan the device's Bluetooth services. UUID-The identifiers can indicate the presence of a communication chip in the system, but for the average user, it is enough to simply check the settings menu on the tracker itself.
- 📦 Check the box for a logo. NFC or"NFC Version".
- 📱 Check the bracelet menu: look for "Payment" or "Cards".
- 🔌 Look at the charger: the versions with NFC Contacts may vary, although not always reliable).
- 🆔 Check the model serial number on the back of the capsule (lamp required).
💡
Notice the color of the strap. Often, but not always, NFC versions came in special packs with an extra strap or had a distinctive marking on the box.
Working with access cards and intercoms
If you're lucky enough to have a module version, the main use case in our latitudes is access card emulation. NFC allows you to read data from plastic intercom keys and bandwidth systems. The bracelet acts as an emulator, copying a unique card ID.
The tuning process is usually done through an app, and you bring the plastic card to the back of the tracker, and the device reads the data, and then when you bring the wrist to the intercom reader, you unlock it, which is convenient, because you don't have to carry the keys.
⚠️ Note: The bracelet only works with standard cards ISO 14443A 13.56 MHz Cards with increased security (encryption), hotel keys or bank cards with a security chip will not be able to copy.
It's worth noting that in global firmware, card emulation is often blocked or limited. Even with a chip in the Chinese version, flashed to the global version, the map add-on menu may disappear, a limitation on the part of the software manufacturer that is difficult to get around without a deep knowledge of modification firmware.
Why aren't all maps copied?
Opportunities of contactless payment in Russia and the world
The issue of payment through Xiaomi Mi Band 4 with NFC in Russia remains open. officially Mi Pay service in our country for this model is not supported. Banks do not add their cards to the Mi Fit application for this device, unlike newer models or smartphones.
In China, the functionality is fully functional: users link cards of local banks (UnionPay) and pay for purchases at terminals. In other countries, including Russia, this feature is either absent or works extremely limited through third-party, often unstable solutions.
There are enthusiastic projects to install third-party software that allows you to emulate the card, but this requires an NFC version and carries the risk of locking the device. For most users, the payment function on the Mi Band 4 remains unavailable.
| Function | Global version | Chinese version (NFC) | Chinese version (without NFC) |
|---|---|---|---|
| Physical module | Absent. | Present. | Absent. |
| Payment in Russia | No. | No (officially) | No. |
| Access maps | No. | Yes (partially) | No. |
| Mi Pay | No. | Only China. | No. |
Compatibility issues and reflashing
Many users are wondering whether it is possible to turn a regular bracelet into a bracelet. NFC-The answer is simple: you can't change the hardware, you can't change the hardware, you can't put Chinese firmware on a global tracker, you can't add an antenna and a chip to the body.
On the other hand, the installation of global firmware on NFC-The system checks the region and disables unused services. You can go back, but the firmware process requires caution and the use of special tools such as mi-band-firmware-patcher.
When flashing, there is a risk of a brick. If the data writing process is interrupted or the firmware file is damaged, the device may stop responding to charging and commands, recovery in such cases is possible only through a programmer, which requires disassembling the sealed housing.
☑️ Pre-firmware check
Alternatives and conclusions
If there is NFC-Payment is critical for you, Xiaomi Mi Band 4 is not the best choice. NFC, Mi Band 7 NFC or Amazfit smartwatches, which have wider support for payment systems and access cards.
Even without NFC, the fourth-generation trackers remain a great health monitoring device: The accurate pulsemeter, step count, sleep analysis and smartphone notifications work consistently on all versions.
In conclusion, when buying a used device or a new one in the store, always check the kit and model. Don't blindly believe the sellers who say that "all Mi Band 4 can pay." Tech progress is moving forward, and the features available in the top models rarely immediately fall into the budget segment.
⚠️ Warning: Buying a hand bracelet, be sure to demand a demonstration of work NFC-functions in the presence of the seller. Check the ability to add a card to the menu of the device.
💡
The NFC in the Mi Band 4 is a regional lottery, and global models are physically devoid of this module, and it's not software-based.
