Figures from payment body Apacs show UK online banking fraud increased from £23.2 million in 2005 to £33.5m last year.

But losses from payment card fraud fell slightly, from £439.4m in 2005 to £428.0m in 2006, with a much sharper 47% fall in card fraud losses at UK retailers – showing the continuing impact of chip and PIN technology.

Fraud in cases where the actual card is not presented, known as "card not present fraud" has risen, with losses up by 16%, and now accounts for nearly half all card fraud losses. To put total fraud losses further into context, however, losses as a percentage of plastic card turnover equated to 0.095% in 2006 – significantly less than the 0.141% figure in 2004.

Apacs attributed an increase in card fraud committed abroad to the growing phenomenon of counterfeiting cards by copying their magnetic stripe. Such cards can be used in countries that have not adopted chip and PIN technology.

Sandra Quinn, communications director at Apacs, said: "These figures clearly show that there is no 'one size fits all' approach to dealing with fraud. Chip and PIN has had a hugely positive effect on fraud losses over the counter in UK shops and stores, but we are seeing more fraud on transactions that do not use chip and PIN – such as over the internet and phone, by mail order and abroad in countries that have not yet fully upgraded to chip and PIN."

She added: "Fighting fraud is never going to succeed with a single-layered approach. It requires different sectors – including public and private -- to work together on developing and implementing strategies, sharing best practice and, most importantly, sharing data."

She called for government intervention "to remove the current barriers" to data sharing and welcomed measures to allow this in the Serious Crime Bill.
