Nippon Shinpan Co. and UFJ Card Co. said Monday they have agreed to adopt JCB's computer software to control key functions in their credit card operations, possibly by the end of fiscal 2008.

The two arms of UFJ Holdings Inc. and JCB, the nation's largest credit card company, said in a joint press release that the UFJ arms will add their own special features to distinguish their credit services from JCB's.

The "trunk system" software developed by JCB governs such functions as credit card and bill issuance, and controls another system for credit card operations.

Nippon Shinpan and UFJ Card said the adoption of the software will free them from having to make tens of billions of yen worth of capital investments.
