Event timing based around Radio Frequency Identification (RFID) technology ('chip timing') has become standard in marathon, triathlon and other mass participation events since the mid-1990s. Athletes wear a transponder chip or tag on their ankle or footwear. This Timing Tag transmits a unique ID code when it is over a timing mat and these ID codes and crossing times are recorded in the Timing Point computer monitoring each mat.
RedTag Timing have developed Timing Points, Mats and Tags built around the same Texas Instruments low frequency RFID components used in the other sports timing systems like Winning Time and ChampionChip timing. However, we have taken advantage of the major developments in the power of embedded computing and networking in recent years to provide significant improvements in providing prompt results and in the information that can be delivered live on the course to help with tracking athletes' progress through the race.
