TSYS Positioned for International Debit Growth

TSYS to Provide Brand-Neutral Support

Columbus, Ga., Dec. 11, 2001 - TSYS® (NYSE: TSS) is poised to capture a greater share of the rapidly growing debit payments market with its licensing of software from ACI Worldwide (NASDAQ: TSAI). Through this offering, TSYS will provide its clients with the ability to switch and route transactions through any PIN-based (on-line) debit network as well as a third-party gateway into international ATM networks. It also allows TSYS to provide its clients with brand-neutral support for any card product.

TSYS will begin implementing ACI's software into its newly designed Integrated Payments Platform, providing the ability to conduct domestic and international PIN-based debit transactions, including on-line transaction processing, switching, routing and ATM terminal driving. TSYS has processed domestic, signature-based (off-line) debit transactions since the 1970s.

According to Nilson Reports, debit card transactions increased 54 percent in 2000, and usage continues to grow as the debit card evolves into more than just an electronic extension of a checking account.

"ACI is the industry-leading software provider for debit networks and by incorporating their software with our Integrated Payments Platform, we will be able to provide direct access to all major ATM networks," said Debra Wohlrab, group executive of TSYS Integrated Payments division. "TSYS will be the only processor to offer the product with the proven architecture and flexible option-driven structure of our Integrated Payments Platform."
"TSYS has a tradition of leadership and innovation, and this new offering reflects their commitment," said Mark Vipond, president of ACI Worldwide.  "As debit card use grows, TSYS can count on ACI's proven software to quickly and reliably route on-line and off-line transactions-and meet the 'always available' processing needs of their clients."

ACI provides TSYS with an integrated processing infrastructure that securely and reliably processes debit card transactions. The system can address a wide range of needs for debit card processing, including multi-currency and emerging security schemes, all on a platform that sets the standard for reliable and scalable transaction processing.
