ChampionChip
From Wikipedia, the free encyclopedia
ChampionChips are a brand name of miniature transponders, marked with a unique identification number, used in many active sports events, to keep track of the competition times of participants.
ChampionChip transponders are waterproof glass capsules that contain a silicon chip and an energizing coil. This coil is inactive until moved into a magnetic field, generated by a send antenna in a mat (used to mark the start and finish lines of a race). The transponder then transmits its unique identification number to a receive antenna in a mat.
These chips are used in many sporting events around the world, including running races, triathlons, cycling and mountain biking competitions, in-line skating and cross-country skiing. Once the chip number is provided to the race administrators, it may be used in any competition featuring the use of this system.
