More than 70 million people in the US will access the Internet from their mobile phones in 2009. So it’s no surprise that retailers such as 1-800-FLOWERS, Amazon, Ralph Lauren and Sears have launched mobile commerce programs so they can be where their customers are.

Nevertheless, mobile commerce is still in its infancy. Web-enabled mobile phone users are much more likely to employ their devices to get weather forecasts, read news, find movie times and bank online than to buy products. Consumers are willing to use their mobile phones to buy items such as pizza, movie tickets and travel reservations. And some have even used their devices to purchase consumer electronics, computers and apparel. But mobile phone users say they would make more purchases if the process were not so cumbersome, products were easier to find and their devices supported secure credit card transactions.

This eMarketer report gives a comprehensive overview of a trend that will change the retail industry in years to come.
