What is the difference between all the Kiosk screen check in options?

There are several check-in options available on the Kiosk display screens.

The Enter Code option requires an attendee to input a unique reference code.  

The Scan QR option requires an attendee to scan a unique QR code.

The Register option links to a registration form from the Registration Element.

The Insert your printed/e-ticket option requires an attendee to scan a unique QR code.

The Scan this code via event app option requires an attendee to access the QR Scanner on the event App. It also requires an attendee to be logged into the event App.

If any option is not relevant to your attendees (or event) you can remove them from the Kiosk display screen by editing the screen options in the Core.
