The European Commission has launched on 17 March 2021 a proposal for a Regulation on the Digital Green Certificate to facilitate safe free movement inside the EU during the COVID-19 pandemic. The Digital Green Certificate will be a proof that a person has been vaccinated against COVID-19, received a negative test result or recovered from COVID-19. It will be available, free of charge, in digital or paper format and will include a QR code to ensure security and authenticity of the certificate. The Commission will build a gateway to ensure all certificates can be verified across the EU, and support Member States in the technical implementation of certificates.
