The Reservation / Meeting Queuing module allows organizers to create a "virtual line" of guests - guests check in, are put "in line", and then can wait anywhere nearby. This is similar to how restaurants manage guests waiting for a table, or how Apple manages customers waiting for help with a purchase. When it's time for the guest to return, the event organizer can send a text message to the guest, then check them in to the station.
This is a custom module that is compatible with Android only. Please contact your Customer Success Manager for pricing and other details.
