On Friday the 26th of April 2019 the MONICA project successfully tested a new feature, the crowd wristband, at the Friday Rock Concert at the Tivoli in Denmark. About 150 visitors to the concert had preregistered a wristband before the concert and 250 additional visitors signed up on the venue before the concert.
Overall 400 wristbands were deployed on the venue. The wristbands will enable to share contacts, find missing persons, get involved in the concert with blinking LEDs and a potentially a deployment for cash payments. Even if the applications to provide this functionality haven’t been fully implemented and the visitors could not look at the information collected during the concert, a survey after the venue showed that these features were perceived as unanimously positive.
