Public transport gets smart

If you have recently undertaken one of the 25 million trips made to, from or within London each day, the chances are you used an Oyster smartcard to swipe in and out of trains, buses or, perhaps, the cable car in Docklands.
Other “intelligent transport” systems in use in London include new contactless payment technology, known as “pay-and-wave”, which went live at the end of 2012 and could one day replace the Oyster card. Paying the capital’s congestion charge via the internet, or using an access fob to hire bikes from the city’s popular cycle-hire scheme, are yet further examples.
