Merchant Customer Exchange CEO Brian Mooney this past week announced the company's mobile payment platform, CurrentC, is now available for use at participating Kmart, Sam's Club, Sears and Walmart locations around Columbus, Ohio, as part of an expanding beta in that city.

Mooney made the announcement during his keynote speech at the Electronic Transaction Association's Strategic Leadership Forum in Scottsdale, Arizona.

The beta will soon grow to include select local Exxon, Mobil and Shell fuel stations, Mooney said. The Columbus beta launched in September at CVS/pharmacy, Giant Eagle, Giant Eagle Market District, Target and Wendy's, according to a press release.

"Our goal is to deliver real value to consumers, incentivizing them to use, and keep using, CurrentC," Mooney said. "By creating the best experience for consumers at every merchant in our network, we think CurrentC can bring consumers and merchants closer together by delivering meaningful and personalized experiences."
