At Danctuary, we use facial recognition to identify our users. It allows us to give them an app-free checkin experience. It allows users to maintain their anonymity by not giving us access to their name or email id. It also allows users to identify other dancers at an event by their face. But most important of all, it allows us to associate previous reports of misconduct with a face and remember that globally. We use those face-associated reports while checking people in to an event.
