Série A Begins Using Semi‑Automated Offside System

The new tool supplies 3D reconstructions to speed VAR reviews while human referees retain final authority.

Overview

  • The system began operating across Campeonato Brasileiro Série A matches on July 25, 2026 and was used in every fixture that round to assist VAR teams.
  • It uses dozens of high‑frame‑rate stadium cameras to track players and the ball, automatically recommending a point of touch and generating a 3D visualization for VAR review.
  • The technology is explicitly semiautomatic: VAR operators validate the computer’s reconstruction and make the final ruling, with a human fallback if the system fails.
  • The supplier — the same company used in the Premier League, Belgium and Mexico — cites prior data from 65 stadiums and 6,903 decisions showing an average 33% cut in decision time, though that figure comes from earlier deployments, not Brazilian matches.
  • Reports differ on whether Brazil’s rollout uses a chip inside the ball; stadium upgrades, operator training and test matches were completed before launch, and broadcasters will show the reconstructions to increase transparency.
