Buying smart health gadgets has become a real challenge today, especially when it comes to the popular Xiaomi brand. The market is flooded with low-quality copies that are almost indistinguishable from the original devices, but their functionality and measurement accuracy leave much to be desired.
Unscrupulous sellers often replicate the original using similar packaging and logos. However, there are reliable verification methods that will help you avoid buying a low-quality product. QR-codes, serial numbers and software.
Where to find identification codes on packaging
The initial inspection starts with the box, because that's where the manufacturer places the basic marking elements. On the bottom or side of the package, a white label with technical information should be pasted. EAN-13, QR-device code and serial number.
Notice the quality of the label printing. On the original Mijia and Xiaomi products, the text is clear, not lubricated, and the stickers themselves are glued smoothly, without bubbles or distortions. Copies are often sinned crookedly with labels or using low-quality paper.
It's important to check the number on the box against the number that's stamped on the device itself, which is usually on the bottom panel, next to the battery contacts, and the discrepancy between the serial number on the box and the case is a complete sign that the device is made from different parts or is a fake.
The barcode must be read by any standard scanner in the store, and if a vendor refuses to hand you a box or says "no need to have a scanner," that's a reason to be wary and refuse to buy.
💡
Always take pictures of the label with the serial number at the time of purchase, which will help in the case of return of goods or contact the warranty center.
Method of scanning QR-code-by-app
The most reliable way to verify Xiaomi’s scales is by using official software, which has integrated verification directly into the process of pairing the device with a smartphone, and you’ll need the Mi Fit app (now Zepp Life) or Mi Home app to do so.
After installing the application and registering an account, you need to add a new device. In the process of searching for scales, the application may offer to scan. QR-code located on the bottom of the scale or on the box, the system instantly checks the unique identifier with the manufacturer's database.
If the scales are original, you'll see the full model name, the exact firmware version, and the ability to upgrade. In the case of the replica, the app will either not see the device at all, or will identify it as "Unknown Device" without full synchronization.
⚠️ Note: If the application offers to download an additional, unknown to you APK-File for scales, stop installation immediately.The original devices only work through official app stores.
The original Bluetooth 5.0 modules used in new models connect in 1-2 seconds. Long device searches or frequent communication breaks may indicate the use of cheap Chinese analogues of chips.
☑️ Checking through the application
Analysis of the EAN-13 barcode
The barcode is a universal product identifier, and its structure is strictly regulated: the first 2-3 digits of the code indicate the country of registration of the brand, not necessarily the country of manufacture. For Xiaomi products, it is often the China code (690-699), but other codes may occur depending on the region of the distributor.
You can check the validity of a barcode with online services or special scanner applications, which will show which product is assigned this number, if the scanner shows "Microwave oven" or "Hearphones", and you are holding a scale, you have a clear fake with the regated code.
The table below shows examples of prefixes and their implications for products related to the Xiaomi ecosystem:
| Code prefix | Country of registration | Chances for Xiaomi | Note |
|---|---|---|---|
| 690-699 | China | Tall. | Basic code for global versions |
| 400-440 | Germany | Medium | For the European Market (EU) |
| 500-509 | UK | Low. | Rarely for weights, more often for other techniques |
| 800-839 | Italy | Low. | Specific regional deliveries |
It is important to understand that having the correct prefix does not guarantee originality, since fraudsters can copy the code from the original box, but the code discrepancy with the declared sales region is a clear alarm signal.
Visual differences between the original and the fake
Chinese replica makers have learned to make very high-quality replicas, but the parts always give them away. First of all, check out the bottom scale panel. The original Mi Body Composition Scale 2 models have a matte plastic, nice to the touch, with perfectly smooth seams.
Forgeries are often found burrs on the edges of plastic, backlash of a glass platform or stickers that start peeling off in the store. Also note the font of the inscriptions: Xiaomi uses a brand font that is difficult to reproduce accurately.
Weigh the device in your hands. The original scales have a certain weight (about 1.5-1.7 kg for the Scale 2 version), due to quality sensors and battery. Too light scales are likely to have a simplified design and cheap sensors.
⚠️ Attention: The absence of a protective film on the glass surface or the presence of air bubbles on it indicates a violation of storage conditions or re-packaging of goods.
Check the battery compartment. The lid should open with a characteristic click, but without excessive effort. Inside should be a polarity (+/-) designation, made by the casting method, not just painted with paint.

Verification of functionality and sensors
Once turned on, the device needs time to calibrate. Xiaomi's original scales show "88.88" or flashing zeros on the screen, then go to standby mode. Replicas can immediately show zeros or have a dim, uneven LED screen.
The main test is accuracy and speed of response. Stand on the scale. The original shows weight almost instantly (in 0.5-1 second). If the numbers run long or the weight jumps when static, the sensors are uncalibrated.
Special attention should be paid to the functions of bioimpedance analysis (measuring the percentage of fat, muscle, etc.) This technology only works in conjunction with the application. If the scales show only weight, but the application claims to support analysis of body composition, it may be that the device does not have the necessary electrodes or they are not connected.
For models that support Mi Fit, check the data synchronization. The original device allows you to upload data to the cloud, plot and compare results. Counterfeiting is often limited to simply displaying weight on the screen without the ability to save history.
💡
Having a bioimpedance analysis (measuring the percentage of fat) only works when synchronized with an application. If the scales show only kg, but the seller promised a body composition analysis, it is a fraud.
