Mobile payments technology, over time, could have a profound impact on the way products are sold, bills are paid and money is transferred around the world.
But some of the experts who look at the new technology say they have questions about the security and privacy issues tied to the payments format.
Executives in the payments industry say the technology is good and getting better.
But security experts say the swift growth of smartphone use inevitably is going to attract fraud. As more consumers use their mobile phones as payment devices, the risks can increase.
Dallas-based NQ Mobile, which provides security software for smartphones, says it saw more than 65,000 new malware threats released worldwide in 2012, up from 24,000 the year before. Malware and phony app sites can direct unsuspecting phone users to sites where they give up sensitive personal information, such as bank account passwords.
"It is a real problem, and it is growing," said Gavin Kim, chief commercial officer of the company. "Smartphone sales are booming, and they are becoming a much more targeted device by hackers." The company sells software that can identify mobile phone apps sites and protect users against malware and viruses.
Interest in the mobile phone security software is growing, but the company estimates that only about 8 percent of the mobile market actually uses security products on phones.
Executives in the payments industry say payments processors and their network of affiliated merchants are constantly improving technology and processes to combat fraud.
