The BBC's consumers' programme, Watchdog, has exposed a security weakness in chip and pin technology that allows fraudsters to harvest security details.
Cambridge University researchers said that the details could be hijacked if a card is put into a doctored payment machine.
Details can then be sent wirelessly to accomplices and purchases made using a fake card with those account details.
A spokesman for UK payments association Apacs said there was no evidence the method had been used in the UK.
This of course is a totally meaningless statement; as it does not mean that this method has not been used, also it does not mean that this method might not be used in the future.
