Timetrack verification in the mobile app with QR code

To prevent manipulation in the form of unauthorized time bookings, it would be interesting to scan a QR code at the place of use. A fixed screen that generates a QR code that can be scanned with clock:it go to record a time.

The screen with the QR code replaces a classic time recording terminal and enables the clock:it go app to be used as a replacement for the RFID token. It reverses the functions of terminal and portable "device".

The QR code displayed on the fixed screen can be seen as an OTP that is invalidated either by a time interval or by a valid booking in the app.
