NFC and payments

NFC connectivity is enabled by default and allows you to add compatible bank cards using Xiaomi Pay. Once set up, certain transactions can be performed without keeping your phone connected.

It also supports emulation of some 13.56 MHz IC access cards. Encrypted, transport, access, or payment cards may have limitations depending on the system used. Actual compatibility depends on the country, bank, card, and services enabled by Xiaomi.

Health and rest

The bracelet allows you to monitor heart rate, blood oxygen saturation, stress, and sleep . It also offers sleep stage analysis, heart rate variability tracking during sleep, and measurements related to nighttime breathing.

The results can be viewed and synced using the Mi Fitness app. These features are intended for wellness and physical activity and are not a substitute for a medical device.

Sports activity
