Goal Line Technology proposes introducing technology to accurately determine if the ball has crossed the goal line during football matches. It discusses different types of goal line technology including microchips in balls and magnetic fields on goal posts. The document argues goal line technology should be implemented because of past incorrect referee decisions not awarding clear goals, like ones scored by Frank Lampard for England and Roy Carroll for Manchester United. It explores what goal line technology is, different existing types, why it should be introduced, and whether it has been tested previously.
