Richard Humbach, manager of mobile payment systems at Nokia, explained that the handsets may need a subtle redesign to cope with how Londoners use contactless payment methods.
"In Singapore's transit system, they wave the card a centimetre or so above the payment pad, but in London they tend to wipe the card on the pad. So the phone may need to be reshaped to avoid scratching the camera lens."
Over 1,000 shops in London now use the Barclays system, which allows for payment without a Pin reader or signature.
Humbach is confident that such payment systems will achieve mass market acceptance "around 2010 or 2011".
