A rapid Covid test which costs just £5 could finally allow Britons back into concerts and sports events.
The Government is reportedly set to buy 200million of the tests which give a 'yes' or 'no' result in 15 minutes.
A negative result would allow millions of people the freedom to socialise and experts say this could be key to moving away from strict coronavirus restrictions.
People who test negative could also receive a 'day pass' to go to the theatre, cinema or a sports event.
Scientists have found the test can detect around three in four positive cases of Covid.

This accuracy goes up to 95 per cent when dealing with people who have a high viral load - which makes people most infectious.
It drops sharply when people have low levels of the virus in their bodies.
Scientists have called for the public to be given lessons on how to correctly administer the test.
There are plans to buy more than 60million rapid tests a month from January, according to The Daily Telegraph, with 192 million purchased in total by March.
The tests are one of those at the heart of the Operation Moonshot pilot and could see the kits used in towns and cities across the UK to help the government get on top of the pandemic by the spring.
Public Health England and the University of Oxford have evaluated 40 lateral flow tests - similar to the ones being used in Liverpool - which are like pregnancy tests in the sense that they provide a 'yes' or 'no' result for Covid within minutes.

The test could pave the way for 'freedom passes' which would let those with a negative result into a sports game or music concert
And it appears that the tests could be used on the 10 per cent of the population who are at greatest risk.
It has been announced that 67 towns and cities will be given 600,000 tests.
Sir John Bell, regius professor of medicine at Oxford, said: 'These inexpensive, easy-to-use tests can play a major role in our fight against Covid-19.
'They identify those who are likely to spread the disease and when used systematically in mass testing could reduce transmissions by 90 per cent.
'They will be detecting the disease in large numbers of people who have never previously even received a test.'
Susan Hopkins, chief medical adviser at NHS Test and Trace, said such tests 'are proving to be accurate and reliable.
'And, importantly they're able to detect covid-19 in people without symptoms who could unknowingly be passing the virus onto others.'
Government ministers announced that relatives of care home residents will be tested for the virus so they can finally visit their isolated loved ones.
An initial scheme will be rolled out across 30 care homes this month.
On another high-octane day of developments in the coronavirus crisis:England's deputy chief medical officer has said he would be 'at the front of the queue' to take Pfizer's breakthrough coronavirus vaccine if he were eligible in a bid to reassure Brits about its safety; Economists have raised hopes the UK's economy could return to pre-pandemic levels within six months after the bombshell news about a vaccine; University students will be offered Covid tests after lockdown ends on December 2 before having a six-day window to travel home for Christmas under the government's evacuation-style plan; Government spending on anti-coronavirus measures has surpassed an eye-watering third of a trillion pounds since the pandemic began, according to analysis by MailOnline.
Britain's official coronavirus death toll passed the grim milestone of 50,000 yesterday after health chiefs announced another 595 victims in the highest daily count since May.
Prime Minister Boris Johnson said the figures was a stark reminder that the UK 'was not out of the woods yet' despite promising news about a vaccine earlier this week. Officials say Covid fatalities will continue to rise for 'several weeks' due to high infection rates though October.
He warned that a vaccine will not deliver a 'knockout blow' to coronavirus as Tories insisted he must not use the prospect of jabs to keep the country in lockdown longer.

At a bad-tempered PMQs session, Mr Johnson again welcomed the news that Pfizer's vaccine had been 90 per cent effective in early trials.
But he gave a stern message to the public that they should not be expecting an early end to restrictions, despite claims it could start being rolled out by Christmas.
He said the 'best way to get this country back on its feet' was to 'continue on the path that we are, driving the virus down'.
The premier said science had given the country 'two big boxing gloves' via a possible vaccine and mass testing, but added: 'Neither of them is capable of delivering a knock out blow on its own.
'That's why this country needs to continue to work hard to keep discipline and to observe the measures we've put in.'

And Mr Johnson is under fresh pressure from angry Tory MPs who are demanding that draconian restrictions are abandoned because they are destroying the economy, risking more deaths from poverty and other diseases that are going untreated.
At least 50 backbenchers have signed up to a new group headed by former chief whip Mark Harper, who has warned that Mr Johnson must not use the prospect of a vaccine arriving early next year to delay decisions on loosening lockdown.
Currently, Tier 1 restrictions are described as 'medium risk' with Tier 2 'high' and Tier 3 'very high'.
Under Tier 3 rules restaurants can open, but only until 10pm and pubs and bars must close unless they also operate as a restaurant.
This definition extends to pubs which sell 'substantial' meals, which like restaurants will be allowed to stay open but only serve alcohol to people eating a meal.
Locals are advised only to leave their areas for essential travel such as work, education or health, and must return before the end of the day.
Overnight stays by those from outside of these 'high risk' areas are also be banned. Households are not be allowed to mix either indoors or outdoors.
