CARREKER ENGAGES E-PAYMENTS EXPERT NANCY LANGER TO HEAD CONSULTING GROUP

Company Reiterates Its Commitment To Payments Consulting Business

DALLAS (March 6, 2003) — Carreker Corporation (Nasdaq: CANIE), a leading provider of technology and consulting solutions for the financial industry, today announced that Nancy Langer, former president of Metavante Corporation’s Electronic Payment and Presentment division, has joined the company as executive vice president of Global Payments Consulting (GPC), a newly structured unit that brings together all of the Company’s consulting services in one payments-focused group.

The assembly of this business unit reflects the company’s emphasis on its payments-related strategy and its commitment to build a consulting business comprised of a broad range of consulting practices that help financial institutions improve their payments business. Carreker’s GPC group complements the company’s two other business units: Global Payments Technology (GPT), formerly called Global Technology Solutions, and Revenue Enhancement (Rev E), completing Carreker’s unified payments solution for financial institutions around the globe.

Langer has extensive expertise in electronic payments solutions. As president of the Electronic Payment and Presentment division at Metavante, Langer grew the division to contribute a substantial portion of the company’s $650 million in revenue. She founded the division, expanded Metavante’s client base for electronic payment solutions, secured long-term contracts with four of the largest global financial institutions and two of the largest global credit card companies, and managed several electronic commerce acquisitions. Prior to this role, Langer was Vice President of Metavante’s Electronic Banking Solutions, which she also founded. Under her leadership, this business unit built the first full service Internet banking Application Service Provider (ASP), which processed the first Internet banking transaction worldwide, and established Metavante as a leading provider of outsourced online banking services.

“We are very pleased to have Nancy’s business-building and payments expertise leading our consulting business,” said Mike Hansen, Carreker’s president and chief operating officer. “Her experience in developing electronic payments offerings complements our existing payments consulting capabilities, and she has an exemplary track record for results. We’re confident that the combination of her skill set and our existing core competencies will allow us to successfully execute this part of our strategic plan and broaden our GPC business to successfully address our clients’ needs in a blended payments environment.”

Carreker’s chairman and chief executive officer, J. D. (Denny) Carreker added, “The assimilation of our consulting services into one business unit under Nancy’s leadership is a critical component of our corporate strategy around the business of payments, a comprehensive initiative that included the Check Solutions acquisition in June of 2001. The experience and proficiency of our GPC group will help extend our existing position in payments, while providing thought leadership and direction for our service and technology decisions. We believe the alignment of our three business units, GPT, GPC, and Rev E, will enable long-term value, growth and success as we pursue the growing market opportunity in the payments business.”
