Timing system using active loop
For sports like running, cycling, triathlon, skiing and low speed motor sport (<120 km/h, <74 mph), we recommend RF transponders or RF-S transponders.
RF transponders are on standby and are activated with an “active” loop. This loop is only for activation, the RF decoder and the transponder communicate by radio. These transponders allow a high detection rate simultaneously with accurate timing.
If your event requires timing a mass run, then the RFID transponder is the best solution. The cost is attractive but the accuracy is lower.
RFID transponders are detected by RFID decoder and they should be used for identification only.
