Some 19% of Americans will use their mobile devices for shopping this holiday season, according to a Deloitte survey. The number is twice as high for young consumers: 39% of those 18 to 29 say they'll use their phones to find store locations, obtain coupons and sales information and research products and prices. One-quarter of all who plan to use their phones to shop say they will make purchases on the devices.

The future of retail will be based on a host digital tools and services. But one of the biggest, most pervasive contributors will be the mobile phone. As phones get smarter and networks get faster, the opportunities for retailers to serve consumers in new ways is nearly infinite. What an exciting time.
