FIFA says it will use goal-line technology at the 2014 World Cup in Brazil, and could have four systems competing for selection.
FIFA says it is seeking tenders from companies which want their system to be used at the Confederations Cup in June and next year's World Cup.
The decision was expected once FIFA's rule-making panel, known as IFAB, decided last July to approve goal-line technology at competitive matches after two systems passed extensive tests.
The camera-based Hawk-Eye system and GoalRef, which uses magnetic sensors, were used at the Club World Cup in Japan in December.
FIFA says two new German systems have completed tests and could soon be licensed for use.
FIFA says it wants to choose its Confederations Cup goal-line system "in early April."
