Scotland manager Berti Vogts has added his support to the possibility of players wearing ear-pieces to communicate with the dug-out.
Fifa have confirmed that the use of communications equipment during a football match will be discussed at the meeting of the International Football Association Board next month.
Vogts believes the system should be tested to help the game move forward.
He told the Daily Record: "When you watch American Football, you can see how it operates with the quarterback being given instructions through an earpiece in his helmet.
"With this system, a manager could change the positions of his players very quickly and give individual or team instructions.
"I think this is worth looking at more closely to see if it would help the game. I believe we should always be trying to move forward."
Dunfermline manager Jimmy Calderwood has already tested the system with his under-21 and under-17 games.
He said: "I was sceptical at first because I've got a big enough mouth anyway.
"But, when you are away to Celtic or Rangers, it can be difficult to communicate with players.
"Using this new system, I can talk to the players and make instant changes without the instructions passed on along a line of players.
"We're going to try it again because I think anything that might help the game should be investigated. We are all always looking for an advantage."
