FIFA has confirmed that goal-line technology will be used at next summer's World Cup in Brazil.
The governing body of world football has already licensed two systems - Hawkeye and Goalref - but has now invited other providers to submit tenders.
Goal-line technology was employed for the first time at last year's Club World Cup in Japan but FIFA will now roll it out during this summer's Confederations Cup, as well as the 2014 World Cup.
FIFA said in a statement: "After a successful implementation of Goal-Line Technology (GLT) at the FIFA Club World Cup in Japan in December 2012, FIFA has decided to use GLT at the FIFA Confederations Cup Brazil 2013 and 2014 FIFA World Cup Brazil.
"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."
HawkEye involves the use of cameras, while GoalRef is a more scientific system, involving a low-frequency magnetic field surrounding the goal and an electronic circuit in the ball, with goal confirmation being transmitted in a fraction of a second to a watch worn by the referee.
A FIFA decision on the preferred provider is due to be made in early April.
