A credit card with a constantly changing security code is being launched in an attempt to combat fraud. 

 

英国将推出一种具有不断变化的安全码的信用卡，以打击诈骗行为。
 

 

The three numbers on the back of the card will be replaced by a digital display randomly¹ generating a new combination every hour. 

 

The digital security company Oberthur Technologies is talking to UK banks about introducing the innovation and has said the cards will be used by French customers by the end of the year. 

 

The security code on the back of most credit and debit² cards is required to make payments online. 

 

Fraud in the UK involving cards, remote banking³ and cheques totalled £755million in 2015, with more than 20,000 victims. 

 

The mini-screen on the new cards is powered by a small battery designed to last three years. 

 

Professor Alan Woodward, a cyber-security expert from Surrey University, said: ‘It's surprising it has taken so long for this to appear. The technology has existed for some time so now it will be a case of persuading card processors that it is worth doing.' 

 

He told the BBC: ‘It may be costly⁴ for card operators as some extra infrastructure⁵ will be required to ensure our cards stay synchronised with the operator, but it happens already for many banks with the dongles they issue for login (to online banking).' 

 

One drawback of the card is that customers will no longer be able to memorise⁶ their security code and will need to check every time they want to make an online purchase.
