The app has been adapted to be compliant with the new regulations announced by the government.

When checking a CovidCheck certificate with the app, you will now be presented with three different options:

- 3G (vaccinated, recovered or tested)
 - 2G (vaccinated or recovered)
 - a "travel" option for official regulations on entering the destination country

In Luxembourg, the person doing the check will have to choose between 3G and 2G, depending on the regime in their location.

"In case of a foreign trip, the person checking will click the "travel" button, scan the certificate and then see flags for the different countries where the application can check if the certificate is valid or not," explains the statement from the Ministries of Health and Digitisation.
