Mangle management -QR Codes

It would be nice if you could link individual defects or entire lists with a QR code. The subcontractor can then scan and edit the QR codes directly without having to be created as a user beforehand. Anyone with the code can edit the associated ticket(s).
Scan → Web view for ticket is loaded → Subcontractor can set the defect to processed and add photos> Responsible person (site manager) receives a push notification and can set the defect to completed.
This is already possible with other providers!
