How can I check-in an attendee using the ticket’s QR code?

First, you need to sign-in in the tickets scanner app. Then, you only need to click on the camera button and point your camera to the QR code.

When the code is read correctly, you will see the ticket status.

If the information is correct and the ticket has not been used yet, then you can confirm the check-in on the screen with one click. After the check-in is confirmed, the ticket can not be used again.
