Five credit unions have agreed to use core processing software from Fiserv Inc.

The Brookfield, Wis., banking technology vendor said Wednesday that the new customers are also planning to use additional products, including online banking, card services, loan origination and check imaging.

Fiserv said that credit unions are increasingly interested in using numerous applications from a single provider, to make it easier to manage their vendor relationships and to simplify the installation process.

The new clients are: Conservation Employees Credit Union of Jefferson City., Mo.; Firefighters Credit Union of Indianapolis; Memorial Employees Federal Credit Union of Hollywood, Fla.; Organized Labor Credit Union of Modesto, Calif., and Electric Federal Credit Union of San Jose.
