Holidaymakers in France are facing vaccine passport chaos as their NHS codes are not being accepted.

       France extended its health pass on Monday to cover bars, cafes and other public areas in addition to museums and other crowded settings.

       Although Britons can load digital QR codes provided by the NHS onto the Tous Anti Covid app, which is also known as the Health Pass, some venues are already struggling to read these.

       Unvaccinated people can also take Covid-19 tests to gain access to venues, but the results of these must either be printed out or uploaded to the app.

       Other businesses across France have outright refused to accept British proof of vaccination, insisting that either the domestic pass or European Union-recognised accreditation is needed instead.

       These include some of the venues participating in Les Rencontres d’Arles, the world’s largest photography festival which is currently taking place in the C？te d'Azur region.

       James Hyman, 54, an art dealer and collector from London, is currently attending the festival with his wife Claire, who works as an NHS surgeon.

       He told The Telegraph that it has been “a lottery” as to which venues accept his NHS QR codes.

       “All around the town of Arle there are different photo exhibitions,” he said. “At every single venue you have to present proof of vaccination and show your ticket but you can’t get into anywhere without showing your pass.

       “I went somewhere yesterday and they turned me away and said ‘we don’t accept the NHS app and you have to get the French one’, which I’ve not got access to.

       “The rule seems to be that unless you can talk your way in, they won’t accept the NHS app as proof and they seem to think it’s legitimate. I’m trying again today but I can’t be sure that we can get in anywhere.”

       Mr Hyman claimed that there should have been clearer guidance on the Government website after France was removed from the UK’s amber-plus travel list, which means that fully vaccinated Britons are no longer required to quarantine on their return home.

       “There ought to be a warning that you’ll be turned away from some places,” he said.

       “Someone should still warn you that if they enforce what appears to be their law, they’re not going to give Britons access, and the first I’ve heard of this shouldn’t have been in France itself.”

       Out of the 10 most popular visitor attractions in France, nine of them now require a Health Pass, while the other is still closed for Covid-19 reasons.

       Tourism hotspots that require a Health Pass as a condition of entry include the Louvre Museum, the Eiffel Tower and the Pompidou Centre landmark, as well as the Disneyland Paris and Asterix Park theme parks.

       France’s vaccine passport system has now been the subject of four weekends of consecutive protests.

       The measures have been introduced in a bid to improve France’s vaccination rates, which trail those of other developed nations.

       Fifty-seven per cent of the French population has been fully vaccinated against coronavirus, compared with 69 per cent of Britons.
