How do bars, event venues and airports check Austria's green pass - and what info do they see?
Bars, restaurants, event venues and airports use an app called Green Check to check Austria's green pass. Here's what you need to know.
As part of Austria's green pass framework, people need to show a valid green pass in order to attend events, enter restaurants and to travel abroad.
The card will allow special privileges for people who have been fully vaccinated, as well as those who have had the virus recently and who have tested negative.
In effect, it is a uniform digitalisation of the existing 3G Rule, which has been in place since May 19th.
While much of the focus up until now has been on how to use the app - which has been frequently difficult and confusing - restaurant managers and event staff are also confused as to how the pass works.
In order to make it easier to carry out checks, the Austrian government has set up a website to help bar and restaurant owners.
Known as GreenCheck, it can be downloaded to mobile phones and tablets.
All that is needed to use the app is that the device has a functional camera.
The GreenCheck app can then check people's Grüner Pass apps to see if they are compliant.
The GreenCheck app simply has a yes or no response to see if someone is in compliance.
The app does not transmit any personal data, or information about the vaccine they had (or whether they are recovered or have tested negative).
In addition, the GreenCheck app can be used offline, making it easier for venue owners to carry out the checks if there is no wifi/data connection.
The app was developed by Austria's Federal Computing Centre (BEZ) under the legal framework established for the green pass.
In mid-August, Austria made its green pass app available in English as well as German. Here's what you need to know.
