France has now got a British border and Belgium is next to get one
But critics blasted the new technology roll out claiming it leaves Britain more exposed to illegal immigration.
The new system is the first of its kind overseas and allows people travelling on EU, Asian, Middle Eastern, North, South and Central American passports to expedite their arrival before they are even in the UK.
Documents can be forged and e-borders foxed which given the problem with illegal immigration in France thanks to the EU's open borders means there are people who will now use this route to get into the UK illegally

John Vine, chief inspector of borders and immigration, said the e-borders scheme had failed to meet its promises three years ago.
And he warned of the potential of terrorists and organised criminals being able to access the country insisting that the expensive scheme had failed to meet its promises.
According to the government's own data, 87 per cent of those travelling to the UK to claim asylum make it past border control before they make their applications, suggesting the current system doesn't work.
Belgium is getting an e-border despite the terror attacks that happened last year
However officials opened the gate in France last week and announced another plan to open one in Brussels later this year despite the UK's plan to leave the European Union (EU).
Ukip home affairs spokeswoman Jane Collins MEP said the government had "made a grave error" replacing people with e-borders.
She said: "We still have a problem with illegal immigration into the UK and we should be investing in human capital and fixing the retention problem which currently exists in the border agency, not replacing them with robots.

"What we need is the experience that comes with working in a profession and developing that instinct for when someone is not telling the truth.

The new gates on foreign soil are in addition to almost 200 ePassport gates in operation at airports throughout the UK.
Home Office officials announced there will be 239 gates in operation across the UK, France and Belgium by the end of 2017.
The cost so far of introducing the electronic system has reached £600m while border staff have lost their jobs up and down the country.
Just a year ago Prime Minister Theresa May, who was then Home Secretary, was slammed after she announced budget cuts with critics identifying both Paris and Brussels as terror hotspots.
Paris has seen more outbreaks of violence and terror than any other city in Europe
At the time Border Security campaign Andy Burnham, the shadow home secretary, said: "A group of the most eminent police and counter-terrorism experts have written an open letter saying that attacks in Paris and Brussels must be a wake-up call for the British Government on lax border security.
"Worryingly the letter reveals that the National Crime Agency has evidence that people traffickers are now specifically targeting weaker sea ports as I have repeatedly warned her.
“Let's be clear about what has just been announced.
“She has just announced to this House a cut, a revenue cut to the Border Force budget."
The UK's Ambassador to Lord Llewellyn hailed the new border insisting that millions of passengers will now be able to access the UK more easily at a ceremony in Paris.
He said: "Millions of passengers travel each year on Eurostar services with both countries benefiting from our close trade and tourism links.
"I am delighted that passengers can now benefit from this new technology which will improve passengers’ experience".

The scheme, devised by the Home Office in 2003, was meant to improve immigration controls.

The Home Office has been approached for comment.
