FIFA have granted licenses to goal-line technology companies Hawk-Eye and GoalRef.

They can now install their systems worldwide.

But world football’s governing body have ordered them to take out insurance policies so that if the systems fail, they’re covered if legal action is taken against them.
The first competitive tournament to use the technology is expected to be December’s Club World Cup in Japan.

The IAFB (international association football board) are the rule makers of football and they approved the use of goal line technology last July after a series of high profile incidents involving goals being incorrectly awarded or denied due to human error.

The two systems are designed with different techniques in mind. HawkEye will use a series of cameras in the staidum to quickly spot when the ball has crossed the line, whereas GoalRef will use a metallic sensor inside the ball to trigger a signal that a goal has been scored.
