Tuesday, small businesses in Copenhagen, Denmark reopened once more, offering services to consumers who are able to present their COVID-19 passports.

At a hair salon in central Copenhagen, customers presented their passports prior to taking a seat.

Customers can either show a negative PCR test no older than 72 hours, proof that they have been vaccinated against the coronavirus, or even proof they previously infected with the virus.

"It feels so good to finally be back", says the hair salon manager, Pernille Nielsen.

Danes became among the first in Europe to begin the use of COVID-19 passport, a key factor in the country's plan to return to a 'normal life.'

Notably, earlier Tuesday, the World Health Organization announced that they do not support the use of a coronavirus vaccine passport for travel purposes due to the uncertainty of the jab preventing virus transmission, and due to the discrimination it poses on those unable to receive a jab.
