In a historic landmark decision, the International Football Association Board (IFAB) and the International Federation of Association Football (FIFA), finally decided to approve the use of goal-line technology. The decision brings an end to a nine-month test period that involved two methods: GoalRef and Hawk-Eye. The former involves a series of sensors around the uprights and the crossbar that alert the ref when the ball has crossed the goal line, the latter requires high-def cameras that will film the ball from multiple angles as it crosses the the goal line. Both methods will get their first test at the 2012 FIFA Club World Cup which takes place this December in Japan. If successful, the technology will make it to the 2014 FIFA World Cup in Brazil.
