Credit, debit, and prepaid card processor Heartland Payment Systems is expanding its Jeffersonville, Indiana, work force by 140 jobs. The company will invest more than $6.2 million in a 50,000-square-foot expansion of its existing Jeffersonville service center.

"We are very proud of the customer service teams we have built in Jeffersonville, and as we have consolidated the processing activities from an acquisition we made in 2008, it was only natural that we wanted to expand those teams to handle the additional servicing activities. Heartland's growth and success are driven by taking great care of our merchant customers, and our merchant servicing efforts in Jeffersonville will therefore remain central to our success going forward," said Bob Baldwin, Heartland's president and CFO.

Heartland expects to add the jobs by the summer of 2011. It has headquarters in Princeton, New Jersey, and is the fifth largest processing firm of its kind in the United States, according to the Nilson Report.
