The International Football Association Board in Zurich have approved the use of goal-line technology in soccer matches. It means match referees will no longer have to decide if the whole of the ball crossed the line without technical help.
Eight companies took part in a first-round of tests to show the board if they have a system in place that will be acceptable to be introduced within the game. Only two met with the approval of the board - GoalRef and Hawk-Eye. They will now both go ahead and make applications to become FIFA goal-line technology licensees.
The technology will make its opening appearance at December's Fifa Club World Cup and, if all goes to plan, it will be used again at the 2013 Confederations Cup and 2014 World Cup. The Premier League in England are keen to use the technology straight away and it could be introduced there by January 2013, reports BBC Sport .
GoalRef makes use of magnetic fields around the goal. The ball is fitted with an electronic device. When the ball fully crosses the line it changes the magnetic field and this change is detected by officials via radio signals within a second.
Eight high speed cameras are used to detect the exact position of the ball. Once the data has been read by the cameras positioned at different angles, it translates an image to video software. A similar system is successfully used at the Wimbledon tennis championships.
Hawk-Eye has already been installed at Wembley Stadium in London but there may still be a delay before either system can be introduced in competitive matches because of licensing, installation and testing restrictions, reports the Telegraph.
