ACI Announces Next Generation Enterprise Banking Solution.

ACI Enterprise Banker 7.3j First All Java, Single Product for Businesses and Consumers

OMAHA, Neb. -- ACI Worldwide (NASDAQ:TSAI), a leading international provider of software for electronic payment systems, today announced the next generation of the company's industry leading enterprise banking product. Version 7.3j of ACI Enterprise Banker([TM]) marks the product's migration to an all Java solution, which serves the needs of businesses and consumers from one product. To date, more than 20 banks have committed to version 7.3j, and three banks have committed to moving online consumer banking clients to Enterprise Banker, in addition to all their business clients. The name of the product was recently changed from Web Cash Manager to Enterprise Banker to reflect the expanded markets it is serving.

"ACI Enterprise Banker 7.3j offers our financial institutions the unique benefit of a product capable of serving all levels of retail and business online banking customers. This offers a number of benefits, including cost reduction by consolidating traditionally separate banking products," said Ralph Dangelmaier, president of the wholesale banking division at ACI Worldwide. "Another benefit is increased cross-sell capability. For example, small businesses that used to be placed on the bank's consumer product, can now take advantage of business functionality with consumer-like usability. As their needs increase, the banks simply activate new options versus forcing the customer to move to a different product. Research has shown that if a customer has to switch products, they often switch banks."

With 7.3j, customers can look forward to usability improvements that increase convenience. Examples include a re-designed dashboard with customizable display options; improved access to critical information with customized alerts and email notifications on action items; and an on-screen view of accounts while making payments, which saves the back and forth of moving to an account inquiry screen. Additional self-service capabilities include automated password resets and online, real time loan payments and drawdowns.
