Mickeycaskill quotes a report from Silicon.co.uk: Rail passengers could use fingerprints or iris scans to pay for tickets and pass through gates, under plans announced by the UK rail industry. In its current form, the mobile technology is intended to allow passengers to travel without tickets, instead using Bluetooth and geolocation technology to track a passenger's movements and automatically charge their travel account at the end of the day for journeys taken. The Rail Delivery Group (RDG), which represents train operators and Network Rail, said further development could see passengers identified using biometric technology in a way similar to the facial-recognition schemes used at some UK airports to speed up border checks. The RDG said more than 200 research, design and technology projects have been identified to increase the railways' capacity and improve customer service. Other projects include new seat designs that could improve train capacity by up to 30 percent and folding seats that could boost space during peak times, including tables that could fold into seats.
