If after registration, trying to scan a QR on a website does not work, check that you have given permissions to the app to access the camera.
This QR reader only works with B-FY's system QRs and in order to be scanned, we need our app to read the QR directly.
If the QR of our system is read with a QR reader app, the system will not work, as it is unique to the B-FY system.
You can change the permissions in system settings-> apps.
