They do issue yellow cards in badminton, just like in soccer! I saw a couple of yellow cards given to a few players in the recent Thomas qualifying round in Malaysia, mostly against the receiver for taking too long to get ready to receive a serve. There was also a yellow card for arguing with the umpire.
I've only seen yellow - about 2 years ago in the Scottish open for rather unsportsman like behaviour on court (not me).
There are yellow, red and black cards for BAofE tournaments. A yellow card represents a warning for misconduct. A red card represents a fault for misconduct, following a yellow card warning. So a red card means you lose a point (or a serve)! A black card means disqualification from the event for serious or persistent misconduct, and can only be administered by the tournament referee.
Yep they sure do my dads a Badminton Unpire and he has given out a few of the old yellow cars but no reds yet
Cai got a red for kicking his bag at the All England Open after their loss to Boe/Moegensen. But it was after the match ended.
Koo got a yellow for asking for the tournament referee after the umpire did not fault Mogensen for being hit in the body by Tan's serve in the Denmark Open 2009.
i remember wang yihan getting a red card for supposedly wiping off her sweat and throwing it on the court and asking for the court mopper to come on, i guess the umpire thought she did it on purpose as a delaying tactic
