OnePulse was the name given to a credit card that was issued by Barclaycard that combined the functionality of Transport for London's Oyster card with a Visa contactless-enabled credit card. Barclaycard OnePulse was launched in early September 2007. Barclaycard has now started to change and simplify its range of credit cards and has started moving all OnePulse cardholders to one of their other cards.
In addition to the normal features of both a Visa credit card and the Oyster product, Barclaycard OnePulse included the ability to pay for low-value items under £20 using the Visa contactless system by waving the card over a reader in participating outlets. Purchases made using either the contactless or standard payment methods were debited directly from the Barclaycard account as opposed to being deducted from the Oyster Pre-Pay account. No PIN was necessary for contactless transactions, providing a similar customer experience to Oyster.
