Barclaycard has unveiled its new three-in-one card, Barclaycard OnePulse, which will combine Oyster transit, credit and contactless funtionalities across London this September. For the next two years at least, OnePulse will be the only combined credit and Oyster card in the UK. An initial pre-registration website is available at www.barclaycard-onepulse.co.uk with the information on the benefits of the card.
