CLEAN : FIFA tests balls that

The video tutorial discusses the unique goal ref technology used in football, which involves embedding passive technology within the ball and setting up antennas around the goal to detect when the ball crosses the line. The system is designed to be seamless, ensuring players do not notice any difference. The tutorial also covers the challenges of integrating this technology with different ball manufacturers and the setup of antennas to relay information to referees in real-time. Finally, it mentions the testing and implementation of the system in Japan, highlighting its potential for future global events.
