An online work hour report app for employees that uses QR codes and GPS location. This app scans QR codes at the workplace (start/end of work) and sends them together with GPS coordinates to the DB server to report the employees' working hours. This ensures that the employee is on site when he carries out the reporting. Additional determination and storage of GPS coordinates and the associated address ensure that the QR code is scanned on site and not at another location. Users must create an account and, after email verification, can log in with email/password, fingerprint or FaceID to use the app. The app also offers an overview of the reported times for evaluation. Employees have access to their own time evaluation, administrators see all employees. The administrators also have access to the admin area of ​​the website and can create and download the QR codes there and then place them at the workstations.
