Abstract
Systems and methods for determining a time of a passing a detection line by a participant having an RFID tag traveling along the route, the system includes a timing system an RFID tag reader system for wirelessly receiving tag reads including a tag identifier for the RFID tags, time stamps each RFID tag read, and transmits them to the timing system, a laser detector detects a laser beam interrupt and generates a laser beam interrupt indicator receives the generated laser beam interrupt indicator, and determines a beam interrupt time, and creates a laser beam interrupt message including the beam interrupt time, the timing system receives the tag read messages and the laser beam interrupt messages, determines the identity of the participant from the tag identifier, associates the laser beam interrupt message with the determined tag identifier, and stores the beam interrupt time as the time of detecting the passing.
