ACI Worldwide to Market Electronic Commerce Solution From Digital Courier.

OMAHA, Neb.--(BUSINESS WIRE)--June 3, 1999--

ACI Worldwide, a leading international provider of EFT processing applications, announces that it has entered into an exclusive agreement with Digital Courier Technologies, Inc. (Nasdaq:DCTI) to relicense Digital Courier's proprietary electronic commerce technologies to ACI customers worldwide. ACI will use the technology to help its customers extend existing payments infrastructures into the rapidly growing world of business-to-consumer electronic commerce.

ACI is granted an exclusive worldwide right to market Digital Courier's e-commerce payments technology. This technology is in use today in Digital Courier's e-commerce processing centers, supporting a wide range of merchants conducting business on the web, domestically and internationally. The solution includes all aspects of handling payments over the web, including value-added features in areas like customer service, merchant reporting and management, and web-centric fraud detection and management. ACI will integrate the Digital Courier solution with its BASE24(R), WINPAY24(TM) and related products, as part of its i24(R)-payments strategy.

"We are extremely excited about this new agreement with Digital Courier, an emerging force in the e-commerce payments industry. The business-to-consumer e-commerce market is exploding, and we're committed to providing our customers with the best in web-centric technologies, to allow them to enter this market in a cost-effective, high-quality fashion," said Jeffrey S. Hale, senior vice president of Strategic Business Development for Transaction Systems Architects, Inc--ACI's parent company. "Clearly, there is significant momentum in the market around e-commerce. This new solution, which we will integrate with our broad range of payments products, including value-added products in areas like payments settlement, fraud management and back-office processing support, will enable our customers to enter the e-commerce space with the most feature-rich solutions available in the market. As our customers move to the web, they want their new solutions integrated with their current payments infrastructure, to avoid the pitfalls associated with multiple payments platforms, back-office inefficiencies and exposure to fraud.

"The combination of Digital Courier's e-commerce technology and ACI's best-of-breed payments processing solutions will represent the finest web-enabled payments capabilities available in the market," Hale added. "The result will be the first end-to-end 'payments portal,' positioned to allow our customers to not only offer web-based features to their consumers, but support them with the most robust infrastructure possible, resulting in efficient, high-quality operations. We believe that this total solution will dramatically raise the bar on the services our customers can deploy in this emerging space."

"We are thrilled to enter into this strategic relationship with ACI, a world leader in this industry," said Mitchell Edwards, chief financial officer of Digital Courier Technologies. "ACI's global reach will bring much greater exposure to our e-commerce technology than we would likely achieve on our own. We view this as a long-term strategic partnership that takes advantage of our respective competitive strengths."
