About goal-line technology

Goal-line technology is a technical means of instantly determining whether the whole of the ball has crossed the goal line.

The International Football Association Board requires that goal-line technology does not interfere with the game, and as such only the match officials receive a signal on their watches to indicate whether the whole of the ball has crossed the goal line.

This information is transmitted within one second, which ensures an immediate response from the referee and that there are no stoppages or other forms of interference in the game. The match officials are the only ones to receive a signal. Unless the competition organiser decides to show a replay, this information is only available to the match officials.

What technologies are there?

Camera-based: Several approved systems work with cameras that detect the ball and use software to evaluate the footage from all the cameras.

Currently licensed systems work with seven cameras per goal installed as high up as possible within the stadium structure.
