The study by professional services firm KPMG found that 85 per cent of US bank customers think mobile banking is important, but they do not want to pay for it.
Another 91 per cent have never tried banking through a mobile device, with 48 per cent of these citing privacy and security concerns as the main deterrent. Some 68 per cent of US customers said their bank does not yet offer mobile banking services.
However, while only nine per cent have conducted banking transactions through a cell phone, smartphone or PDA, 19 per cent said they expect to use mobile banking over the next 12 months as services become more widespread.
Nevertheless, 66 per cent of consumers told the survey they were still uncomfortable using a mobile device for financial transactions.
KPMG's Mitch Siegel said: "US consumers - as well as worldwide - need to be convinced that new payment methods and banking vehicles are safe and secure for them to succeed."
