Holidaymakers are at risk of being banned from popular attractions in France under new proposed restrictions.
Tourists visiting the country will have to prove they are fully vaccinated or face being barred from eating and drinking in bars, pubs and restaurants.
From today, people will need to show details of their jab status, a negative test or that they have fully recovered from coronavirus.
The move is part of French president Emmanuel Macron's vaccine passport certification system plan, which has been rolled out to most public places - including the Eiffel Tower.
UK tourists can show a QR code from the NHS proving vaccination status to gain entry, instead of having to upload it to a French version of the app, according to reports.
Fines for customers who refuse to show the health pass start at €135 (£115) and can escalate to as much as €3,750 or even six months in prison for repeat offences.
The same punishment applies to those using false certification or information belonging to someone else.
Business face closure if they fail to check, with pubs, bars and restaurants at risk of being hit by a fine worth as much as £1,300.
Under the UK's new travel rules that came into force on Sunday, fully vaccinated people and children can now visit France without quarantining on their return home.
France is on the amber list, although unvaccinated travellers still have to self-isolate at home for 10 days.
Mr Macron has previously said: “It’s about citizenship. Freedom only exists if the freedom of everyone is protected…
"It’s worth nothing if by exercising our freedom we contaminate our brother, neighbour, friend, parents, or someone we have come across at an event. Then freedom becomes irresponsibility.”
From 30 August, all those whose job brings them into contact with the public must have the pass or face being suspended from their jobs without pay.
