The days of having to get in the car to go shopping are long gone, and the era of logging onto a desktop computer may be soon to follow, as a new report found consumers are increasingly using their mobile devices to make purchases.

According to a new study by eDigitalResearch and Portaltech, 50 percent of surveyed smartphone owners said they have used their mobile devices to complete a purchase online. Furthermore, 11 percent of respondents indicated they now use their devices to shop online on a weekly basis.

This study's findings seem to reflect a growing level of confidence that consumers have in their mobile devices. In a similar study conducted nine months ago, only 30 percent of smartphone owners said they had used their devices to make purchases online.

"We are entering into an age of MEcommerce; a shopping revolution where the consumer now has the power to dictate to retailers where, when and how they want to shop and interact," said eDigitalResearch director Chris Russell.

The findings of this study are reflected in a recent report by mobile advertising network firm InMobi, which found mobile sales doubled from 2009 to 2010, increasing from $1.2 billion to $2.4 billion.
