How does the application Tečka work?

You can load certificates for one or more persons (e.g., family members) to the application Tečka by gradually registering the persons at the Public Vaccination Portal (Očkovací portál občana) or by scanning the QR code from their certificates (on paper or in other forms). After the first login to the Public Vaccination Portal, the application will connect automatically. The application then automatically downloads certificate updates (e.g., the second vaccination dose, new test results, etc.) for the person logged into the portal.)
The application shows the list of persons and the list of loaded certificates for each of them, marking the certificates’ validity. The application assesses electronic signature and validity of the loaded certificates without Internet connection, using stored parameters alone.
The application displays the QR code and identification information of the holder for each certificate when it is necessary to present them to controllers. If necessary, it is also possible to view the details of the certificate, including information on the vaccine type or a taken test.
The application updates its parameters (validation regulations and signing certificates of EU countries) and the certificates for persons logged into the Vaccination Portal every time it is opened or at the request of the user.
