Will Goal Line Technology help stopping goal like Lampard's 2010??

England midfielder Frank Lampard's infamous un-allowed goal against Germany in FIFA world cup 2010 has raised some questions for the manual decisions vs inclusion of Goal line technologies. At half time England and Germany could have been at 2-2; They were not and the score was 2-1 in favor of Germany as Referee disallowed the Lampard's goal. Since then there were enormous discussion on the topic and finally The International Football Association Board (IFAB) has approved the use of goal-line technology (GLT) in football matches after a nine-month testing period.

In a statement from IFAB, "a final installation test at each stadium was required before the systems could be used in “real” football matches"
