There are two easy, convenient ways to check-in event goers.

Mobile Check-In

You can use the free TicketLeap app on an iOS or Android to scan QR codes on each ticket. TicketLeap Scan is a quick and efficient method for mobile and printed tickets. 

For more information, refer to: Introduction to the TicketLeap Scan app

Attendee List Check-In

You can also check in attendees using the attendee list. You have the option to check in attendees per ticket or order. Cross-reference the names of attendees on the list with those present at the event, and use the corresponding check-in option.
