The International Football Association Board (IFAB) agreed to re-open discussions on the topic on Wednesday.
An IFAB statement read: “The indication of whether a goal has been scored must be immediate and automatically confirmed within one second.”
The IFAB wants technology companies to present ideas by the end of November.
Systems would then be tested in advance of the next IFAB meeting in March, when the next stages of the process of implementation would be discussed.
The statement from Fifa’s rulemaking division added: “The technology would apply solely to the goal-line, and only to determine whether a goal has been scored or not.
“The system must be accurate. The indication of whether a goal has been scored will only be communicated to the match officials.”
Fifa had called time on goal-line technology experiments in 2008 after deciding that systems which worked in other sports – such as the Hawkeye innovation used in tennis and – were unsuitable for football.
It also tested a system using a microchip in the ball but decided it too complicated and not accurate enough.
But after incidents such as the Frank Lampard goal that was disallowed in England’s 4-1 World Cup loss to Germany despite clearly crossing the line in June, it decided to take another look at possible solutions.
Fifa president Sepp Blatter said it would be “a nonsense not to re-open the file” on technology and referred the matter to the IFAB.
The IFAB also heard an update on the experiments with an extra assistant referee behind each goal-line.
The system is currently being tested in the Champions League, Europa League and Euro 2012 qualifiers, as well as by the French Football Association, the Moroccan Football Association and the Qatar Football Association.
Further experiments will start next year in the Ivory Coast, Mexico and Brazil.
