What do the umpires in badminton use red and yellow cards for?

Answer 1

The yellow card stands for warning, which is a reminder to a few players of their faults. If the player or the same side is in misconduct again, the umpire will give a red card, then one point will be awarded to the opponent. In another case, after the umpire showing a red card, if the fouling party continued to foul again, the umpire may apply to the referee for the ejection of it. After the referee verifying it, he would license to a black card to the umpire for the execution of the ejection.
