Zurich, Switzerland – Goal-line technology was approved on Thursday by the International Football Association Board, which determines the laws of soccer.
The IFAB, composed of FIFA and associations in England, Scotland, Wales and Northern Ireland, made the decision at a meeting Thursday, but the technology may not be used by all associations.
FIFA plans use the technology in the 2012 Club World Cup in December, and will debut the new system in the World Cup in 2014 in Brazil.
The IFAB approved both GoalRef and Hawk-Eye goal-line technology after a nine- month period of tests.
Goal-line technology has long been a debated topic in the sport and was again an issue in Euro 2012, when Ukraine had a goal against England disallowed that appeared to cross the line. England won, 1-0.
Although FIFA has approved the technology, UEFA could decide not to use it in its competitions, such as Euros and the Champions League.
The IFAB started "technology will only be utilized for the goal line and for no other areas of the game."
The IFAB also approved the use of two additional assistant referees, who are stationed on the goal lines. These assistants have been used during a two-year experiment, and the association acknowledged "the support they can provide in officiating football matches."
The IFAB also unanimously approved, "temporarily during a trial period," the wearing of head scarves.
