Data on all passengers leaving the UK is to be collected and handed to the Home Office under a scheme being phased in at ports and border crossings.
Transport staff will record details of all travellers leaving by commercial air, sea and rail transport.
The exit checks will particularly affect travellers on cross-channel ferries and the Channel Tunnel.
The government said they were needed to combat illegal immigration and would cause the “least possible disruption”.
For the first month all passports will be scanned but only 25% of the passport holders will have their details verified to ensure they are genuine, in a bid to minimise disruption.
After a month, there will be a move to 50% verification and by the middle of June 100% verification will be introduced.
What are Exit Checks?
Data will be collected on all passengers as they leave the UK on scheduled commercial international air, sea and rail routes.
The government says exit checks are “predominately an immigration and data tool”, giving a “comprehensive picture” of whether people leave the UK when they are supposed to.
It says the data – gathered by airline, rail or ferry operator staff – will “improve our ability to identify and further tighten the immigration routes and visas that are most vulnerable to abuse”.
It will also help security services “track the movements of known or suspected criminals and terrorists”.
