Goal-line technology has finally been approved by the International Football Association Board after a meeting in Zurich. Both Hawk-Eye and GoalRef passed Fifa's criteria, following a unanimous decision. But the sport's governing body is yet to decide on which system they prefer. The technology will be first used at December's Fifa Club World Cup in Japan and if successful, at the 2013 Confederations Cup and 2014 World Cup. After nine months of testing in England, Germany, Hungary and Italy, the IFAB admitted the decision had to be made to give referees more assistance during the game. Hawk-Eye's system works by using six cameras, focusing on each goal, to track the ball on the pitch. The system's software then uses 'triangulation' to pinpoint the exact location of the ball. GoalRef uses a microchip implanted in the ball and monitors low magnetic waves around the goal. Fifa's president, Sepp Blatter, admitted he had changed his mind about the technology after Frank Lampard's disallowed goal for England against Germany in the 2010 World Cup. The controversial issue also reared it's head at Euro 2012 when Ukraine were denied a goal against England. The Premier League has welcomed the decision and says they will implement the new technology 'as soon as practically possible.'
