Timing chips are small electronic devices used in various sports events to accurately record the time it takes for participants to complete a race. These chips are typically attached to a runner's shoe or bib and work by sending signals to timing mats placed at the start and finish lines. This technology ensures precise timing, which is crucial for competitive events. In addition to running, timing chips are also used in other sports like cycling and triathlons. They help organizers track performance and provide participants with reliable results. The use of timing chips has become standard in events organized by groups like USA Track & Field and Ironman.
