Denmark launched a COVID-19 "passport" scheme on Tuesday that will help to allow non-essential businesses to reopen to customers.
The "coronapas" is available via a secure application or in paper format to people who have either been fully vaccinated, have tested positive for COVID-19 two to 12 weeks previously or negative over the previous 72 hours.
It currently allows people to enter certain businesses — including hairdressers, beauty salons and driving schools — with the aim to gradually reopen the economy by the end of May.
It will be expanded to include terraces, which are due to reopen on 21 April, and restaurants, museums, theatres and cinemas from 6 May. The country is scheduled to be fully reopened on May 21 when the government estimates it will have vaccinated people over the age of 50.
"I've been waiting for three months to get my hair cut," Rune Højsgaard, a 42-year-old computer scientist, said after brandishing his "coronapas" at the salon.
"I had a test on Saturday, it's valid until this afternoon. I'm used to getting tested once or several times a week so it's not really a problem for me," he added.
Hairdresser Pernille Nielsen is similarly "excited" to be allowed customers after four months of closure.
"We have waited so long for this reopening! Now we are doing everything we can to be able to reopen and if that (the coronapas) is what we have to do, then we are doing it," Nielsen said.
