Referee decisions in sports branches can be a matter of discussion many times. Competition Decision Assistance System is the use of electronic assistance for issues such as whether a ball has crossed the line (goal, ball inside out, etc.). In detail, it is a method to assist the referee in deciding when exactly the ball has crossed the line with the aid of electronic devices simultaneously.
We continue our efforts to develop a system that uses advanced and up-to-date technologies of the VAR systems used in football and GDS systems used in volleyball.
The purpose of this system is not to change the role of authorities, but to support them in their decision making.

In addition to football, the system can be used in many branches such as volleyball, handball, tennis and badminton.
