Business Editors & Technology Writers

OMAHA, Neb.--(BUSINESS WIRE)--Oct. 1, 2001

ACI Worldwide (Nasdaq:TSAI), a leading international provider of enterprise electronic payment solutions, announces that its corporate banking business unit is changing its name to IntraNet, Inc.--the name it was known by before its acquisition by ACI's parent company in 1998. IntraNet will roll out its new name and logo at the SWIFT SIBOS trade show in Singapore, October 15-19.

"We're adopting a new identity to establish a distinct brand and focus for our wholesale banking solutions," said Dennis Jorgensen, president and CEO of IntraNet. "Nothing else has changed. We are the same company, the same management, and have the same ownership. Our infrastructure remains the same. We will continue to provide the quality service that our customers have always known, but with increased vigor and excitement.

"IntraNet will focus on the wholesale banking market with the support of TSA--our parent organization--and a continuing partnership with ACI Worldwide--our sister company."

Over the past 25 years, IntraNet has become the market-dominant provider of high-value payment systems to the largest financial institutions in the U.S. In recent years, the company has used its expertise and its relationships with major international banks and other companies--especially IBM and Compaq--to extend its franchise into the international arena, particularly in Europe, the Middle East and Africa. IntraNet's solutions have expanded from processing systems for high-value payments to software that accommodates bulk/ACH payments, global messaging, Continuous Linked Settlement (CLS(TM)) and integrated payments.

IntraNet's product strategies will continue to focus on the use of componentisation, object-oriented architecture, portable design methodologies, rich graphical user interfaces, and the integration of open languages and e-business tools including Java, XML, WebSphere and DB2. IntraNet's electronic payments solutions embrace proven technologies from IBM including IBM Framework for e-business, a roadmap for integrating Internet technologies with traditional information technologies.

IntraNet will continue to offer solutions that give its customers the ability to react quickly to changes in the payments and messaging environments, reduce cost structures, increase service levels and take on more business. These solutions are particularly suited to the integration of complex, mission-critical systems.

"Recent licensing agreements with international banks such as Deutsche Bank and Mizuho Financial Group, and a new contract with a top European international bank, demonstrate that our products continue to gain respect and awareness," Jorgensen added. "These customers need global systems that are capable of expanding as their business grows across many countries.

"We have been particularly successful in Europe recently because our research and development work is bearing fruit and underpinning our active sales campaign. We have some solid expertise and experience in our niche markets and are building excellent reference sites. We have concentrated over the past months on strengthening our products, enhancing them for the future and for our customers' future."

In addition, this press release may contain other forward-looking statements including statements regarding Transaction Systems Architects, Inc.'s ("TSA"), its subsidiaries or third parties' expectations, predictions, views, opportunities, plans, strategies, beliefs, and statements of similar effect. The forward-looking statements in this press release are subject to a variety of risks and uncertainties. Actual results could differ materially. Factors that could cause actual results to differ include but are not limited to the following.

The success of TSA, or any of its subsidiaries, entering into a new distribution or partnering arrangement depends on numerous factors including the acceptance of the distributed products or services by TSA's existing customer base and integration of the products and services into TSA's marketing efforts, the quality of the products or services as perceived after use by TSA's customers, and the degree of competition from competitive products or service providers.

TSA's business is concentrated in the banking industry, making it susceptible to a downturn in that industry.

TSA is subject to risks of conducting international operations including: difficulties in staffing and management, reliance on independent distributors, fluctuations in foreign currency exchange rates, compliance with foreign regulatory requirements, variability of foreign economic conditions, and changing restrictions imposed by U.S. export laws.

Fluctuations in quarterly operating results may result in volatility in TSA's stock price. No assurance can be given that operating results will not vary. TSA's stock price may also be volatile, in part due to external factors such as announcements by third parties or competitors, inherent volatility in the high-technology sector and changing market conditions in the industry.

For a detailed discussion of these and other risk factors, interested parties should review TSA's filings with the Securities and Exchange Commission, including Exhibit 99.01 to TSA's Annual Report on Form 10-K for the fiscal year ended September 30, 2000.
