Mobile banking and the use of mobile devices such as cell phones, smartphones, and personal digital assistants (PDAs) for financial transactions and payments are increasingly gaining acceptance among U.S. consumers, according to results of a survey conducted by KPMG LLP-- the audit, tax and advisory firm.

The results of KPMG’s fourth annual Global Consumers and Convergence survey show that 19 percent of U.S. consumers have conducted banking transactions on a mobile device, compared to only 9 percent when KPMG last completed this survey 18 months ago. More than 5,600 people in 22 countries worldwide participated in the survey, which examines trends in the use of mobile technology.

Among age groups, U.S. consumers age 16-24 conducted mobile banking the most with 33 percent of the respondents in this bracket indicating they have conducted banking on a mobile device. Among all U.S. respondents who have not conducted banking through a mobile device, 52 percent cited security and privacy as the primary reason.
