DMEA sparks opened, featuring a wide range of topics. Federal Minister of Health Jens Spahn kicked off events. In his interview he focused on the coronavirus contact-tracing app, which was presented to coincide with DMEA sparks. "It is decentralised, voluntary and complies with the DSGVO" - which according to Spahn were only a few of the requirements. Only if people widely accepted the app and large numbers installed it would it be able to fulfil its purpose, he said.
