Work is being carried out to develop coronavirus freedom ‘passports’ that will allow those who have tested negative to enter pubs, schools and workplaces.
Two firms have been awarded Government contracts for exploratory work on a new app that would allow people to prove they do not have Covid.
The Department of Health said no decisions had been made on introducing the passport.
The contracts envisage a system under which people are assigned a QR code on their smartphones linking to a digital passport that includes a photo of them.
After a Covid test, this would be updated at the test centre and when people want to enter a venue they could present their QR code as proof of their negative status.
