SVPCO FORMS ALLIANCE WITH CARREKER ON CHECK 21 READINESS EDUCATION

Bank Demand for Check 21 Education Growing in Wake of Legislation

DALLAS, TX (December 9, 2003) — Carreker Corporation (Nasdaq: CANI), a leading provider of technology and consulting solutions for the financial industry, today announced that the Small Value Payments Co (SVPCo) has formed an alliance with Carreker to deliver Carreker’s Check 21 Workshop to SVPCo financial institutions.

Carreker’s Check 21 Workshop is an intensive two-day set of sessions designed for all areas of a bank impacted by Check 21. It is delivered on site at the client bank, tailored to the client’s business strategy and technology environment and focused on ensuring that the bank’s Check 21 response is synchronized across the enterprise. It includes a comprehensive post-workshop analysis of the relative preparedness of each area of the bank and a detailed report that guides the bank’s ongoing preparations and prioritization.

Hank Farrar, president and chief operating officer of SVPCo, which is owned by 22 of the largest U.S. banks and The Clearing House, said, “The pace of image exchange and associated planning has stimulated a demand for Check 21-related education. From conversations with participating banks, we felt that Carreker’s Check 21 Readiness Workshop was setting the standard for Check 21 education and preparedness, so we chose Carreker to help us bring SVPCo participants the best introductory services for improving the understanding of Check 21 implications.”

Nancy Langer, president of Carreker’s Global Payments Consulting division, said, “We are gratified to see our relationship with SVPCo evolve to include this important educational component. Our Check 21 workshops contrast sharply with others by getting ‘behind the firewall’ to tailor our content to each client’s circumstances and needs. We don’t just prepare the bank for the immediate Check 21 impact, but for all the domino effects we foresee across the bank, and we give them tools to sustain their efforts.”

Carreker has contracted its Check 21 Readiness Workshop for twelve leading banks. The company was also chosen by Wells Fargo to develop image exchange software, called ExchgLink™, for sending and receiving image files and software for ensuring image quality, called Image Inspector™. Both solutions will be in pilot in 2004. For more information, visit Carreker & Check 21.
