Barclaycard and Orange want to expand the use of some trailed technology which will enable credit card users to use their contactless mobile phones to pay for stuff by "waving" or swiping the card next to a receiver.

Research by Analyst firm Informa Telecoms & Media showed that by 2013, around 300 billion mobile transactions will be performed with an average value of around £2 each. That's up from 250 million transactions last year.

Another study showed that around one in every eight people have used a contactless prepaid card. Barclaycard already has a standalone product called OnePulse which combines Oyster card with a credit card and a Contactless card in one.
