An expert has welcomed Barclays' move to make Oyster payments available on its debit and credit cards.
Oyster is used to make payments on London's underground rail network - which will mean that Barclay's credit cards can be used for three separate transactions - also including chip and pin - from next year.
Robert Kenley, head of credit cards at Moneysupermarket.com, has said that innovation of this nature is applauded in the credit card market - but warned that work is still needed for a full rollout of the system.
Additionally, the expert claimed that the new credit card system could lead to confusion for consumers over which area of their cards are being debited.
"The risk lies not within the pre-pay element of the Oyster card - which can only be spent when the card is topped up and cannot be overdrawn - but more within purchases being debited from the credit or debit side of card."
Oyster cards can be topped up in a variety of ways, including debit or credit card payment online, before being used to access transport.
