On the sports field, athletes uphold the Olympic spirit of "faster, stronger, higher". However, the corresponding sports judging technology must also keep pace with the times.
RFID used in track events
     Track events are a type of track and field sports, and are a general term for running and walking competitions that take place on a track or prescribed road in a track and field. The electronic tags with personal information on the participating athletes are laid with carpet antennas at the starting point and end point of the track. After connecting to the reader, the tags are sent to the backstage through RS232 or TCP/IP as the basis for the referee.
