A facial recognition system designed to replace the need for tickets on trains is being tested in the UK.

An early version that uses two near-infrared lights to help a single camera determine texture and orientation of each pixel it captures was shown to BBC Click.

The system, being developed by the Bristol Robotics Lab, is being partly funded by government and the private sector.

Researchers told the programme that they believe it will successfully identify passengers without the need for them to stop walking and could replace ticket gates.
