Unisys Corp. of Blue Bell, Pa., said Thursday it has sold its payment systems operating unit to a Los Angeles private-equity firm, Marlin Equity Partners.

The unit, now called Burroughs Payments Systems Inc., is based in Plymouth, Mich. The company provides hardware and services for image capture and payment processing to banks and processors.

"Marlin's financial and operational expertise combined with our industry-leading products and focus on customer service will enable" the newly-formed company to "increase market share," Alan Howard, Burroughs' president, said in a press release.
