Your face could soon become your train ticket

Researchers have created facial recognition software that could one day allow you to use your face as a train ticket.

A team from Bristol Robotics Laboratory have developed the 3D software, which can pick out the smaller details of people's faces, like their wrinkles, to differentiate one person from another.

Lyndon Smith from Bristol Robotics Laboratory told BBC Click: "You can imagine that, if you can get rid of the gate lines in a place like Victoria station, there's a massive potential for increasing throughput.

"So we ran an interesting project for [Cubic], which they're installing at their laboratory in Salfords [in Surrey] and the aim is to move it onto the underground. You can imagine, for example, paying just by means of presenting your face to a system rather than having to use the card and pin."

The software would even be able to differentiate between identical twins as it can detect the smallest of moles and even a person's pores.

Dr Melvyn Smith, Director of the Centre for Machine Vision, added to MailOnline: "Everybody's face is unique in three dimensions actually. Even identical twins are unique. 3D imaging can distinguish features like moles and pores which are different on identical twins.

"With a 2D imaging system you could use a picture but to avoid that the 3D information finds shape in space. You could only fool it if you could carry a 3D representation of your head."

And Justin Vaughan-Brown, Director of Technology Strategy for EMEA at AppDynamic, has likened the technology to e-passports.

He shared: "While many passengers may be sceptical about using their face as a means of financing future travel, the idea in its simplest form will already be familiar to those who use e-passports, and the technology that allows us to go hands-free.

"The future of train ticket validation may lie in facial recognition, but the potential of the technology will only be realised if consumers receive a flawless experience. With the current tap-and-go policy so familiar to the majority of commuters, facial recognition must offer something more than what's already on offer."
