A credit and debit card processor has announced plans to expand its operations in southern Indiana and hire up to 140 more workers by next summer.

Heartland Payment Systems said Tuesday it will spend more than $6.2 million to expand its Jeffersonville service center, where it now has about 650 workers. Princeton, N.J.-based Heartland says it will be hiring customer service and management personnel early next year as construction and renovations begin.

Heartland president Bob Baldwin says the Jeffersonville center was a natural site for the company to consolidate processing operations from an acquisition it made in 2008.

Indiana Economic Development Corp. said it offered Heartland as much as $1 million in performance-based tax credits and up to $200,000 in training grants. The city of Jeffersonville also will provide a property tax abatement.

The company also provides gift marketing, payroll and check management services. Heartland processes more than $80 billion in credit and debit card transactions each year, making it it fifth-largest such firm in the country.
