PHILADELPHIA (CBS) — McDonald’s restaurants have expanded a cashless program that lets customers round up their bill to the nearest dollar and donate to the Ronald McDonald House Charities. Digital kiosks and counter registers now allow people to donate without using cash.

The systems were tested at multiple locations, including at Philadelphia-area McDonald’s restaurants.

Danielle Dawkins-Alston, who owns and operates six area McDonald’s restaurants, had one of the systems at her locations. She said before the round-up technology existed, her restaurants collected spare coins in donation boxes.

“But now that we’re moving to a more cashless society, the donation boxes were collecting less and less over the years. So this is a way for our customers to donate their change, rounding up to the nearest dollar,” Dawkins-Alston said.

As of Dec. 10, McDonald’s says, the Round-Up for RMHC technology has been installed in around 14,000 locations nationwide. During its testing phase, it collected $2.2 million.

The company says customers can round up at the counter as well.
