The present invention discloses a passive radio frequency (RF) tag module. The passive RF tag module comprises a shell. A microprocessor, a radio frequency chip, a radio frequency antenna and a powergeneration module are installed in the shell. The power generation module is used to provide the working power and a bullet fired signal for the microprocessor; the microprocessor analyzes the signaland stores the number of fired bullets; the radio frequency chip and the microprocessor implement two-way data transmission; the microprocessor writes the number of stored fired bullets into the radiofrequency chip; and the radio frequency chip transmits the number of fired bullets to an external device through the radio frequency antenna. According to the passive RF tag module disclosed by the present invention, a passive technology method is used, the reliability of the passive RF tag module is improved, and the technical problems that the adoption of the active technology needs maintenanceand the like are solved. 本发
