Danctuary app runs its checkin algorithm to see whether the user should be allowed at this event or not. Any user blocklisted by the event organizer or triggering the event's filter criteria will be denied checkin to a Danctuary supported event.
An event-organizer can check people in to their events with the Danctuary app. The app clicks a picture of the user's face and runs it through its database of globally blacklisted users. If blacklisted, the user is denied entry to that event. After checkin, the picture clicked during checkin is visible to other dancers in the current-event-attendees section on their Danctuary app. Clicking a picture at every checkin thus enables users to then identify another dancer based on their most recent picture.
