A chip embedded in a football which alerts the referee if the ball crosses the goal line, is still being considered for the professional game.
Investigation into the use of goal line technology has stepped up once again.
Adidas and Cairos Technologies have submitted a solution to the FA that is being considered.
The technology being looked at now is based on a chip in the football sending an encrypted radio signal to a watch on the referee’s wrist. The chip senses when the ball crosses the line as the penalty box and an area behind the goal contains cables running different rates of electricity. The electricity creates varying magnetic currents which the ball picks up. When the ball receives the signal that it has crossed the line, the referee receives the signal.
The next step is for a professional league to trial the technology. Should the results prove positive, the technology could be rolled out to the professional game globally.
