COPENHAGEN, Denmark (AP) — The Danish government has presented its digital coronavirus passport enabling people to travel abroad or, in Denmark, go to the hairdresser, a tattoo parlor, dine inside a restaurant or wherever else it is needed. During a news conference Friday outside the Copenhagen airport, Denmark’s health minister held up his phone to show the app, which shows a QR code and a green bar if the person has been fully vaccinated or has recently tested negative. People will either have it scanned or will flash it before entering an airport, a harbor, a train station, a hairdresser or an eatery.
