Among other things, a new version of the semi-automatic offside technology will be introduced, and VAR reviews will be shown on large screens. In addition, the referees will wear body cameras during the matches.
Images from the referees' body cameras will be shown directly in the TV broadcasts.
The goal with the news is an improved experience for referees and the audience.
Swedish referee Glenn Nyberg, together with his assistants Mahbod Beigi and Andreas Söderkvist, forms the only Swedish referee team in the tournament.
Fifa also announces that an AI-driven solution will be used to collect match data, and that the teams will register substitutions digitally on tablets, instead of on paper as normally used.
The plan is for the technology to then become a new standard in international football.
The Club World Championship starts on June 15 and lasts until July 13.
