Cambridge Consultants Ltd. has devised a wireless tagging technology that is claimed to provide a step-change in the capabilities of paperless transport ticketing. With it commuters could have an invisible licence to travel, eliminating barriers in railway systems while allowing staff to target only those passengers travelling without tickets. The idea uses ultra-wide band radio technology that operates over a wide frequency range and short distances. The wide bandwidth emission makes it very robust to interference and it needs much lower power transmission levels than narrow band communications such as GSM.
