Disposable wrist watch based on RFID mobile positioning

The utility model discloses a disposable wrist watch based on RFID mobile positioning. The wrist watch includes a watch head, a watch band, an RFID emitter and a power supply. The RFID emitter and the power supply are both arranged in the watch head. The watch head includes an upper cover and a watch body. Through grooves are arranged on two symmetrical side walls of the watch body. Four fixing columns are arranged in the watch body. The two ends of the watch band are provided with through holes corresponding to the fixing columns. The two ends of the watch band pass through the through grooves and then sleeve the fixing columns. Two fixing columns, close to the power supply, are connected respectively with positive and negative output ends of the power supply. Two fixing columns, close to the RFID emitter, are respectively connected with positive and negative input ends of the RFID emitter. Two metal wires are arranged in the watch band. Metal sleeves are arranged in the through holes of the watch band. Metal sleeves of the two ends of the watch band at the same side are connected through metal wires.
