FIFA is willing to allow goal-line technology decisions to be shown to fans on big screens in stadiums and television viewers.
In a document to be assessed by football's rule-makers on Saturday, FIFA has reversed its previous stance that referees could be undermined if the results from the high-tech aids were revealed.
Competition organisers will be able to prevent the outcome being publicly known as it is in tennis, however, while referees have the power to ignore the goal-line decisions.
"The question of whether and how replays are shown on TV or on an LED screen in a stadium should be one of the first discussion points when starting the implementation of goal-line technology"
"The question of whether and how replays are shown on TV or on an LED screen in a stadium should be one of the first discussion points when starting the implementation of goal-line technology in a competition,'' says a FIFA document on the implementation of goal-line technology.
"FIFA recommends involving referees in this discussion as well, due to the fact that the main objective of GLT (goal-line technology) is to support and protect the referee."
A fourth system of goal-line technology has been approved and granted a licence, FIFA also said on Friday.
FIFA said that the German-produced GoalControl 4D used 14 high-speed cameras placed around the pitch and directed at both goals to determine whether the ball had entered the goal.
"The position of the ball is continually and automatically captured in three dimensions as soon as it approaches the goal-line," said FIFA in a statement.
"When the ball has completely crossed the line, the central analysis unit sends an encrypted signal to the referee's watch in less than a second. GoalControl 4D can be used with both standard goalposts and balls."
On Monday, the German-manufactured Cairos system, which uses magnetic fields around the goals, was also granted a license.
The systems previously approved are Hawk-Eye, which is used in tennis and cricket and like GoalControl is optical-based, and GoalRef, which uses magnetic fields.
FIFA approved the use of goal-line technology last year following a number of controversial incidents where teams had legitimate goals disallowed because officials wrongly judged that the ball had not crossed the line.
European soccer's governing body UEFA has yet to adopt goal-line technology, preferring to employ an extra linesman behind each goal.
The four systems will all participate in a tender to provide goal-line technology at this year's Confederations Cup and the 2014 World Cup in Brazil.
FIFA used both GoalRef and Hawkeye at last year's World Club Cup in Japan, when goal-line technology was used for the first time in professional matches. However, only one system is likely to be chosen for the World Cup.
On Thursday, the English Premier League announced that its clubs would be obliged to set up goal-line technology systems in their stadiums from as early as next season.
