Case Study: Sun Federal Credit Union achieves 1,034% increase in credit card balances with Fiserv

Sun Federal Credit Union Partners with Fiserv for Successful Credit Card Program

Sun Federal Credit Union, a 12‑branch credit union based in Maumee, Ohio, faced the limitations of a single credit card offering — a fixed‑rate uChoose Rewards® card from Fiserv — and needed expert guidance to compete as credit card usage grew. Sun Federal worked with Fiserv to assess its portfolio, member base and competitive position and to identify the right mix of new products and go‑to‑market approaches.

Fiserv implemented a new card lineup using Credit Full‑Service Processing, helping Sun Federal launch three distinct cards (exclusive/affluent, cash back and low‑rate), conduct marketing and sales training, and pilot an affluent product. The program drove measurable results: applications up 64%, new card issuance up 39%, credit card portfolio balances up 1,034%, and average credit limits increasing from $1,600 to $6,000, demonstrating Fiserv’s tangible impact.
