OMAHA, Neb.--(BUSINESS WIRE)--June 5, 2003

ACI Worldwide (Nasdaq:TSAI), a leading international provider of enterprise e-payment solutions, today announced the licensing of its integrated chip card technology to Standard Bank Group, the largest banking group in Africa ranked by assets and earnings. The ACI solutions pave the way for Standard Bank customers to receive simpler and more convenient bank-issued card services, ultimately with multiple applications on a single smart card.

Standard Bank licensed ACI Smart Chip Manager(TM) to issue and manage a large volume of smart cards to meet the issuing requirements of EMV (the global specifications defined by Visa and the recently merged Europay and MasterCard to ensure interoperability between chip cards and terminals).

Standard Bank is currently testing the solution in terms of both the local and international environment. The first phase of this smart card implementation provides a limited number of internal users with a Standard Bank credit card certified by MasterCard. Using this technology in the future, the bank's customers could have multiple applications on a single card. Several other applications are under consideration by Standard Bank to fully utilize this channel to bring new and innovative services to their customers.

Standard Bank's decision to select ACI's chip card technology was prompted by a number of key requirements, including the need for a solution that would allow the bank to evolve from single-application to multiple-application EMV card products; the need to reduce fraud and meet mandated dates for EMV acquiring and issuing; and Standard Bank's intention to work with the leading e-payments solutions provider.

"ACI is a recognized leader in payments systems, and its chip card technology provides the features we need today, with the flexibility to enhance our future offerings," said Dr. Alewyn Burger, Executive Director of Standard Bank. "ACI's Smart Chip Manager allows us to begin issuing credit-based single-application chip cards and acquiring transactions from them -- and then expand our offerings to multiple-application cards when it is appropriate for our customers and when the market is ready."

ACI Smart Chip Manager enables Standard Bank to issue a variety of smart card platforms and to keep control over the entire smart card real estate. It allows Standard Bank to develop new smart card programs and add new card products, meanwhile keeping the active schemes up to date with the latest status, applications, parameters and information. As card numbers and business grow, Smart Chip Manager employs parallel processing for high performance throughput and bandwidth.

"We are proud to welcome Standard Bank to the growing list of ACI clients in the region - with every customer we work very hard to provide new and innovative services to their consumers," said Jeremy Wilmot, managing director of ACI Worldwide's sub-Saharan operation headquartered in South Africa. "Our Johannesburg office is closely involved in this project together with ACI's Smart Card Division in the Netherlands to ensure the best possible outcome for Standard Bank in this strategic initiative. This is backed up by our global pool of professional services staff experienced in delivering large projects in the chip card arena."

ACI's chip card technologies support more than 20 million multiple-application cards on different operating systems/smart card platforms worldwide.
