A digital Covid certificate system that will facilitate travel within the EU became operational ahead of schedule in seven countries on Tuesday. The ‘digital green certificate’ records whether people have been fully vaccinated, recovered from the virus or tested negative within 72 hours.
Travellers can move freely if at least one of these three criteria is met. Bulgaria, Czech Republic, Denmark, Germany, Greece, Croatia and Poland made the certificates available. The system would be used in all 27 EU countries as of July 1.
