Fifa will use goal-line technology at the 2006 World Cup in Germany if a trial run at the Under-17 World Championships in Peru proves a success.
HOW IT WORKS
Computer chip embedded in ball
Pitchside sensors track movement
Decision relayed to ref by buzzer
A 'smartball' system has been developed whereby balls fitted with a microchip will send a signal to the referee when they have crossed the line.
"We will definitely use the technology in Germany if the experiment works," said Fifa president Sepp Blatter.
A decision will be made by world football's governing body in October.
The tournament, running from 16 September to 2 October, in Peru will host 32 matches at four venues each featuring the technology that has been developed to use the 'smartball' system.
If there are no incidents requiring the goal-line technology a special match will be arranged to take place at one of the stadiums.
Blatter added: "The International Board will attend that last week of the competition in Peru in order to see how the system works.
"This goal-line technology is enough. Football must keep its human face and must accept errors. If we start to make it too scientific this game will lose its fascination."
