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.
The incoming technology will be designed to help match officials with critical decisions in matches, and its use appears to have been hastened by England being denied a goal in their defeat to Germany at the 2010 World Cup.
A shot from Frank Lampard hit the underside of the crossbar and replays showed it clearly crossed the line, however Uruguayan referee Jorge Larrionda did not award a goal, which would have been an equaliser. With the assistance of a goal-line camera, the costly mistake would not have been made.
Tennis and cricket at the highest level already feature the use of technology, with umpires and players able to turn to replays of key incidents for clarification.
Blatter said at the Club World Cup that FIFA would follow suit.
"The one thing I can say is that the referees are happy to have this help for them because they know now that if there's a conflicting situation it is possible to get the assurance to say if it was or wasn't a goal," Blatter said in December.
