Although there is no longer a certificate requirement in this country, individual cantons can still define areas where certificates are required. In addition to this, many countries, particularly in the Schengen area, will continue to require a COVID certificate for entry in the future.
This means it’s to your advantage to keep your COVID certificates somewhere safe. You can do this digitally in the COVID Certificate app, as a PDF or in paper form. Please note that if you uninstall the COVID Certificate app, all the COVID certificates it contains will be lost. The same applies if you change or lose your smartphone.
