There're three ways admins can check-in attendees to event.
#1 Guest Check-in tool
To Check-In an individual attendee at your event, go to Contacts and click on Guest Check-in. (Search for the name of the attendee if you do not see it in your currently open list.) Click on Check-In switch below the attendee's name to check-in attendee to event. See screenshot below.
#2 Event check-in using QR code
Additionally, a volunteer can check-in attendee using the built-in Event Check-in scanner in the Dryfta event app. The scanner would scan the QR code in the attendee's badge and then checks the attendee into the event.
For volunteers to be able to view the Event Check-in scanner, they need to have an Admin account. Using the admin login credentials, volunteer can log in to the app and view the Event Check-in Scanner under the App Navigation.
#3 Check-in an individual attendee to the event
To Check-In an individual attendee at your event, go to Contacts. (Search for the name of the attendee if you do not see it in your currently open list.) Click on Check-In button in the left and attendee shall be checked in. See screenshot below.
The concerned attendee also receives an automated email that he/she has been checked in to.
