The rfid smart wristband is used to record the upper body movement data of the user. The shoe clip records the lower body movement. The two devices can be used separately. When not in use, the shoe clip is directly placed on the wristband to avoid loss. The rfid sports wristband is built-in. A plurality of sensors and infrared sensors can detect physiological signals such as heartbeat and blood oxygen content while detecting user movements; the self-contained sensing function on the wristband can also measure the user's body temperature.
