Facial recognition technology to end train tickets

Facial recognition technology could mean that queuing to buy a train ticket and waiting to go through the barriers may be a thing of the past. The cameras use high speed infrared lights to capture the shape and texture of the face in detail never seen before - even spotting small blemishes and wrinkles. Researchers say they could identify passengers as they walk onto the platform and the time-saving technology could be rolled out in the UK by 2020. Facial recognition identifies people by analysing the shape of a person's face. Each face has approximately 80 unique nodal points which distinguishes one from another.
