Built-In QRCODE Scanner User not user

Hello! Does BEtudom set the built-in qrcode scanner so that non-users can also read it?
It hasn't worked so far. The goal would be that anyone aware of the link should be able to collect data with the built-in scanner.
There would be 70 users, and we don't want to give everyone a separate user
Can you help?

Hi

They needs certain permissions to be able to use the scanner. I would suggest you to create one user account, then give them the username and password so that they can use that same user account for scanning QRCODE to checkin registrants
