Michael O'Neill's side were beaten 1-0 by Switzerland thanks to a Ricardo Rodriguez penalty in the World Cup play-offs after Corry Evans was wrongly adjudged to have handled Xherdan Shaqiri's goalbound effort in the first leg in Belfast.
The decision infuriated the Northern Ireland boss, who said after the game: "it's just staggering in this day and age when the stakes are so high that something like that is a game-changer.
"It (a VAR) should be used for anything that is a defining decision, which is clearly what we saw.
"A penalty given in those circumstances, a VAR would have cleared it up and said it's clearly not a pen."
The 'Press Association' reports that the IFA could now write to FIFA to back the imprlementation of VAR in high stakes games.
The IFA is one of five members of the International Football Association Board, football's law-making body, giving them significant influence over the potential implementation of VAR on a large scale.
