Chilling face of the future: As train companies say they'll use facial recognition technology to replace tickets... how the technology could strike at our right to privacy...

There are few sights more dispiriting than a long queue at ticket offices or machines when you’re rushing to catch a train. However, technology is now offering an ingenious solution.
