BROOFKIELD, Wis. – Fiserv’s Credit Union Group added 52 new core processing credit union clients in 2003. Fiserv has the most credit union clients in the industry with 3,107. With the addition of IntegraSys last year (the former EDS credit union processor), it now has seven data processing subsidiaries – USERS, AFTECH, Galaxy, Summit, CUSA Technologies, XP Systems, and IntegraSys. Fiserv made some moves in 2003 to regionalize its CU business. It named Joe Barry, former president of USERS, as president of its Eastern Region credit union business, responsible for the USERS, AFTECH and Galaxy subsidiaries. Fiserv already had a Western Regional president in Roger Kuhns, former president of CUSA Technologies, who oversees Summit, XP Systems and CUSA Technologies. IntegraSys is on its own with president Scott Butler overseeing its product lines.
