Chip timing
From Wikipedia, the free encyclopedia
Transponder timing (also called chip timing or RFID timing) is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event.

Prior to the use of this technology, races were either timed by hand (with operators pressing a stopwatch) or using video camera systems.
