So this app will be used for going to bars and restaurants? From what I read, it's for Germans who have been vaccinated and in their system - and that is still in a state of chaos. I'm sure (at least for the short term) that the CDC card I have to bring with me won't be accepted - either for the app or by the venues that require vaccination.

Looks like I may be limited to take-away and delivery at the hotel again.
