- Goal-line technology
FIFA's goal-line technology green light
FIFA has confirmed goal-line technology will be introduced in time for the 2014 World Cup.
It will also be used at the Confederations Cup, which takes place in the country from June 15 this year, the governing body said.
A statement on the FIFA website read: "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."
FIFA has launched a tender and is inviting goal-line technology providers to apply to supply the systems, with the final decision on the provider to be made in April. Hawk-Eye and GoalRef both have FIFA approval.
Goal-line technology has been the subject of debate for several years. England famously scored against West Germany in the 1966 World Cup final when Geoff Hurst's shot cannoned down from the crossbar, while England were denied an equaliser in their quarter-final defeat to Germany at the 2010 World Cup when the officials failed to spot that Frank Lampard's effort had crossed the line.
