Active tags are attached to each bicycle’s front fork in cycling races and to each runner’s bib in long-distance running races. The tag emits radio waves* when triggered by a magnetic field at the finish line, thus ensuring accurately recorded race times.
*Average of 200 pulses per second.
Even if dozens of competitors cross the finish line simultaneously in the final sprint of a cycling race, all goals can be recognized.
The RaceReader has a resolution of 0.01 seconds. It is practically used for measuring the time of race cars travelling at 180 km/h.
