Mass Checkout is a helpful tool to mass checkout attendees. The organiser has the option to check out all attendees or only attendees under a specific price level.
This feature is great for events that run for multiple days. The organiser can mass checkout the patrons at the end of the day so that customers can still reuse the ticket on the following day.
Note: It is imperative that the organiser remembers to do the mass checkout at the end of each day as failure to do so will make the tickets invalid in the upcoming days.
