Labs Talk Podcast: The Corona-Warn-App with Thomas Klingbeil

SAP is developing the so-called “Corona-Warn-App” – Germany’s official contact tracing app.  While SAP’s role is to develop the iOS and Android applications, Deutsche Telekom is focusing on a scalable backend service for these applications.

The first open source documents were available on May 13, 2020 and the first code drop followed over the next days. At the time we conducted this interview, the Corona-Warn-App is a few days to being released publicly.

We’re lucky to be in touch with Thomas Klingbeil, Senior Developer at SAP and part of the application’s project team. Together with Thomas, we will explore the features of the app, discuss what Bluetooth Low Energy is,  how it can be used for contact tracing and especially highlight the privacy preserving nature of the overall Corona-Warn-App system.
