If you are hosting an in person event, you will be able to check in guests as they arrive in order to verify their registration and to keep attendance.
Guests will receive a QR code in their email that you can scan when they come to the event. You can also search for their name on the guest list to check them in manually.
We also have an iOS app that you can download here: https://apps.apple.com/us/app/luma/id6444549793
