ZURICH - Goal-line technology will be used at the 2014 World Cup and two more systems could be considered in addition to the existing pair, soccer's world governing body FIFA said on Tuesday.
Two systems, Hawkeye and Goalref, have so far been licensed by FIFA and both were used at last year's World Club Cup in Japan, one in each of the two stadiums, where goal-line technology was employed for the first time.
FIFA said a third system, developed in Germany, had already passed examinations and that the providers were in licensing discussions. A fourth system, also German, has also been tested with the results due this week.
FIFA confirmed goal-line technology was "successful" at the World Club Cup, although there were no incidents where it had to be used.
It intends to install goal-line technology at all 12 venues at the 2014 World Cup in Brazil.
"After a successful implementation of goal-line technology (GLT) at the Club World Cup in Japan in December 2012, FIFA has decided to use GLT at the Confederations Cup Brazil 2013 and 2014 World Cup," FIFA said in a statement.
"The aim is to use GLT in order to support the match officials and to install a system in all stadia, pending the successful installation, and pre-match referee tests.
"With different technologies on the market, FIFA has launched a tender today, setting out the technical requirements for the two forthcoming competitions in Brazil."
FIFA said Hawkeye and Goalref would have to join the selection process.
Goal-line technology providers had been invited to join an inspection visit to the six Confederations Cup venues in March. Those venues will all be staging matches at the following year's World Cup.
