Germany launched the rollout of the certificates late last week. Users can download proof of their coronavirus vaccination status onto a smartphone app.
Pharmacies across the country started issuing certificates on Monday to people who have been fully vaccinated and so far have only analogue proof.
The certificates can also be issued on-site by large vaccination centers. German officials say they have already been used by travelers at European borders without problems.
German Health Minister Jens Spahn said as he arrived at a meeting with European Union colleagues in Luxembourg on Tuesday that 5 million certificates would be issued by the end of the day.
As of Monday, 22.3 million people in Germany had been fully vaccinated, 26.8% of the country’s population.
