Facial recognition technology aims to cut passport queue times - BBC News
The UK Home Office is considering a system which would let you walk through immigration without showing your passport.
Millions of passengers pass through UK airports every year, and those numbers are projected to double by 2050.

New technology has been developed that uses a combination of facial recognition technology and your mobile phone in a bid to speed up the immigration process.

The UK Home Office and Border Force are considering using the technology in the future.

The BBC's Simon Browning has been to test it out.
