The "Green Pass" app was developed to display the certificate stored on the smartphone in PDF form or as an image. However, the certificate must be available as a file on the smartphone.
Green Pass can be operated offline after installation. No internet connection is required.
The contents of the displayed files remain unchanged.
You can also display the certificate via another PDF viewer or via the Gauls. GP does not change any data, does not read anything and does not transmit anything.
If you operate your smartphone in dark mode, GP is also displayed in the dark design.
