In association football, goal-line technology is a method used to determine when the ball has completely crossed the goal line with the assistance of electronic devices and at the same time assisting the referee in calling a goal or not. The objective of goal-line technology (GLT) is not to replace the role of the officials, but rather to support them in their decision-making. The GLT must provide a clear indication as to whether the ball has fully crossed the line, and this information will serve to assist the referee in taking his final decision. In the wake of controversial calls made in the Premier League, 2010 World Cup and the Euro 2012, FIFA (previously against the technology) is testing potential candidates for goal-line technology. Nine systems were initially tested, but only two remain.
On 5 July 2012, IFAB officially approved the use of goal line technology. The two systems approved in principle were involved in test phase 2: GoalRef and Hawk-Eye. In December 2012, FIFA announced it would introduce goal-line technology in a competitive match for the first time at the 2012 FIFA Club World Cup in Japan.

Famous quotes containing the word technology:
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
