The Department of Health and Human Services will promote HealthCare.gov at the bottom of some 7-Eleven receipts in an effort to reach demographics that could be uninsured, the department announced Thursday.

The department is partnering with PayNearMe, an electronic payment processing system that lets businesses process large cash payments. Stores such as 7-Eleven, Family Dollar and ACE Cash Express stores use the app; Individuals can pay for utilities, rent, travel tickets or other expenses in cash using the app, if the business is a PayNearMe customer. Payers select the business they’re paying through the PayNearMe app online, print out a barcode, and take the cash payment to a nearby store in exchange for a receipt of payment. PayNearMe usually takes a transaction fee, which can work out to around $3.

Starting today, and until the end of the open enrollment period for insurance under the Affordable Care Act, PayNearMe receipts printed at all 7,800 7-Eleven stores in the United States will direct payers to HealthCare.gov.

HHS Secretary Sylvia Burwell demonstrated the system at a 7-Eleven in downtown Washington on Thursday in a small press event attended by Sunnyvale-based PayNearMe chief executive Danny Shader.

The partnership is an effort to reach potential customers where they already are, Burwell said.

“We know that the populations we’re trying to reach, many of the uninsured are those who . . . are unbanked,” Burwell said. “Those are the people that PayNearMe reaches. We want to try and reach those populations.”

This new campaign builds on a recent one at Westfield Shopping Centers, which agreed to let HHS employees hand out information about the health insurance marketplace on Black Friday.
