One of the biggest pains with coat checks isn’t the slow attendant who takes forever to come back with your coat. It’s the ditsy ones who switch coats and hand off the wrong ones to people who don’t bother to check. I’ve lost a few coats because of similar occurrences and it was enough to ruin an otherwise good night.
Potentially eliminating mishaps like this in the future is the ECLIPS system. It does away with claim tickets by employing an invisible ink stamp (which goes on invisibly on the person’s wrist) and UV lamp scanner (which the attendant uses to scan people’s wrists.) A clip is attached onto the coat, which comes embedded with a LED light that blinks when said person is ready to claim their coat.
