Goal-line technology will cost as little as £100,000 to install in a stadium, FIFA general secretary Jerome Valcke has claimed.
Speaking after an International FA Board meeting in Edinburgh which approved the use of goal-line technology replays on television and big screens, Valcke said that the bottom price was the "lowest six-figure" sum but that a decision would also take into account servicing and maintenance costs and demands.
However, contrary to previous reports, replays in stadia would not take place if it was a controversial decision that undermined the referee.
FIFA has had tenders from the four licensed companies to install systems for the Confederations Cup and World Cup in Brazil, while the FA and Premier League are in talks with two of the firms over putting the technology into English top-flight clubs and Wembley Stadium.
"We have talked about the use of the replay, and because that can be controversial, and when there is a risk of creating a problem for referee in the stadium, then there will be no broadcast of the replay," Valcke said.
The IFAB, the game's law-making body, also ruled that competition organisers can allow the technology to be used in competitions such as the FA Cup even if not all the clubs have systems in place.
FA general secretary Alex Horne told a news conference: "My view that I will recommend to the FA Cup committee is that technology favours nobody - it is there for both teams so if at any stage where a club enters and have that we would allow them to switch it on."
The other major decision made by IFAB was regarding its own composition - it is made up of the four British associations who each have one vote and FIFA which has four votes. The structure will remain the same but it is proposed to set up two advisory committees - a technical panel made up of referee experts and a football panel of former players and coaches.
Stewart Regan, the chief executive of the Scottish FA who hosted the meeting, said: "The IFAB has agreed that greater levels of consultation are required to provide greater transparency and opportunities for other associations and stakeholders to contribute with ideas and initiatives to benefit the game. This will need to be approved by FIFA Congress in May."
The IFAB also agreed to set up a group of sports scientists and medical experts to look into the benefits of electronic performance monitoring systems - a chip in a player's shirt which can transmit back immediate information such as heart-rate and distance covered.
New wording on the offside law was also agreed to make it clearer for referees to rule when a player in an offside position is interfering with play.
