Referee technology refers to the various tools and systems used to assist officials in making accurate decisions during sports events. This includes technologies like VAR (Video Assistant Referee) in soccer, Hawk-Eye in tennis and cricket, and goal-line technology that helps determine if a ball has crossed the goal line. These innovations aim to reduce human error and enhance the fairness of the game. These technologies provide real-time data and video replays, allowing referees to review critical moments and make informed choices. By integrating technology into officiating, sports organizations strive to improve the overall integrity and enjoyment of the game for players and fans alike.
