pretix-cwa 1.1.2

pretix integration for the Corona Warn App (CWA)

This is a plugin for pretix. It integrates pretix with the German Corona Warn App (CWA) by making it easy for event organizers to generate event QR codes while at the same time making it really easy for attendees to use them and remind them of using it.

It currently supports the following features:

• Generate a QR code that can be used to check in to the event using the CWA. The QR code can be displayed as a self-refreshing website, printed to paper, or embedded into a digital signage system as a PNG or SVG image.

• Automatically send a link that allows to check-in using the CWA as soon as the attendee arrived. This is sent via email immediately after the event ticket has been scanned at the entrance. This way, people are actively reminded of doing the check-in (even if they do it only afterwards), but the link is only shared with people who actually show up.

We decided against printing the CWA qr code on tickets since the CWA FAQ recommend to not make it available for people not physically present to avoid misuse.

The configuration of the plugin allows to control whether a new QR codes is generated with every time slot, or just once per day.

It is built based on MaZderMind’s implementation of the CWA event registration spec.
