 A `QRCodePayload` is base32-encoded and included in a URL. The URL is the content of the QR code and structures as follows:
 
 ```text
-HTTPS://E.CORONAWARN.APP/C1/<ENCODED_PAYLOAD>
+https://e.coronawarn.app?v=1#<base64-url_encoded>
 
 # example:
-HTTPS://E.CORONAWARN.APP/C1/BIPEY33...
+CWA Germany:

+CLEA FR:
+https://tac.gouv.fr?v=1#Y2xlYQ==
 ```
 
 The base32 encoding allows to leverage the input mode _alphanumeric_ when generating the QR code and produces a QR code with a lower density compared to base64 encoding.
