Since it is no longer possible to warn other users through the Corona-Warn-App regarding an increased risk of infection as of May 1, 2023, you can no longer use the QR codes created on this page or with other tools to register for events and locations. As such, the information on this page is related to features of the app that are no longer available as of May 1, 2023. For more information, click here: What is the background for the end of the development of the CWA?

Create QR code for event check-in

The app allows a check-in for events and locations. People who host events or have a business can create a QR code. By scanning the QR code, guests can check in upon arrival to register their presence. If desired, the app will also create a corresponding journal entry. If a checked-in person later tests positive for the coronavirus, other people who were checked in at the same time can be warned.

You can create QR codes in the app or here on this page. Alternatively, you can also use our official QR code utility to generate several QR codes at once, for example. Click here for a detailed guide on how to use the official QR code utility.
