The EU Digital COVID Certificate has reached another important milestone with the go-live of the technical system at EU level, which allows to verify certificates in a secure and privacy-friendly way. The EU certificate was proposed by the Commission to resume safe travelling this summer. It will be free of charge, secure and accessible to all. Available in digital format or on paper, it will be a proof that a person has been vaccinated against COVID-19, tested negative, or recovered from an infection.
