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:
https://e.coronawarn.app?v=1#Y3dh...
NotifyMe CH:
https://qr.notify-me.ch?v=2#bm90aWZ5bWU=
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.
