How does the Xiaomi Smart Scale S200 identify users?

After the device is bound, the scale will save your information. Later measurements will match users based on weight differences and synchronize measurement data.
Note:
1. Users with a weight difference in the range of ±2kg cannot recognize it;
2. It is recommended to use the share device function of the account and share it with another person. When using it, keep the Bluetooth connection to measure. When offline, the scale cannot recognize the only user.
