Transport for London (TfL) has hit a speed bump on its plan to implement contactless “wave and pay” technology across its transport network, according to Computerworld UK.

The transport originally made plans in October 2010 to introduce contactless payments ahead of the 2012 London Olympic Games this summer. However, due to “complexities with the technology” and on-going developments with the card payments industry, a full roll-out will not be possible until the end of 2013.

TfL will implement the technology in phases, following a trial set to begin next month, firstly across its 8,500 strong bus network, which will be followed by a wider roll-out to London Underground, London Overground and the Docklands Light Railway (DLR).

“We will only roll it out once we are confident it is 100% robust,” said Shashi Verma, TfL’s director of customer experience.
