The system isn't always available for outdoor markets in parks or parking lots, and small markets often can't afford to set up the technology.
Two years ago, Jeff Dabbelt of Lexington Farmers Market in Lexington, Ky., set up a machine on his own to accept EBT payments. "I had to convince my directors that it was going to be worth the additional cost," he said.
Last year, the market brought in $14,000 from EBT cards, Dabbelt said.
"There can be some inherent business that comes to your table just by the machine being there," he said.
Although he had to go through bureaucratic channels to set up the machine, he was happy to learn that the federal government will offer some assistance to smaller markets.
Currently, of 7,100 USDA-registered farmers markets nationwide, 1,500 accept EBT cards, according to government figures.
The use of the cards at farmers markets has quadrupled since 2008. "I'm all about it," Dabbelt said. "It's almost a necessity, if not outright 100 percent necessary."
"That assistance would be invaluable all across the country," he said.
Health experts say a lack of affordable healthy food in low-income communities is directly related to high obesity levels.
"The retail food environment is not the same in every neighborhood," Brian Smedley of the Health Policy Institute at the Joint Center for Political and Economic Studies said this week at a Centers for Disease Control and Prevention obesity summit.
While recent studies have found that poor urban neighborhoods don't lack grocery stores, some experts say that finding fresh, affordable produce remains a challenge.
According to a federal study released during the CDC's "Weight of the Nation" summit, the lack of access to healthy foods directly contributes to high U.S. obesity rates.
"As the trends show, people have a very tough time achieving healthy weights when inactive lifestyles are the norm and inexpensive, high-calorie foods and drinks are readily available 24 hours a day," said former Agriculture Secretary Dan Glickman, the chair of the committee that produced the report.
