A third of America’s small business owners are using smart phones these days, and most of them are putting the devices to work for business needs beyond e-mail and phone calls, according to a recent survey from Discover.

And while they may not be using smart phones themselves in great numbers, 19 percent of small business owners have taken or are currently taking actions to make it easier for mobile users to access their businesses.

“Small business owners are clearly paying attention to mobile-driven consumer trends, and are looking for ways to adapt,” said Ryan Scully, director of Discover’s business credit card, who has been commissioning monthly surveys of American small business owners for over four years. “Being flexible and adaptable to a changing economy has helped small business owners succeed through the years, and I wouldn’t be surprised to see new entrepreneurs push the limits when it comes to mobility.”

Thirty-four percent of small business owners indicated they use a smart phone device, compared to 26 percent of 3,000 consumers questioned in the survey. Among the business owners who use their smart phones for more than e-mail and phone calls, 33 percent of them said they use the devices “very much,” 41 percent said they use it “somewhat,” 21 percent said “not much,” and only 3 percent said “not at all.”
