ACI Money Transfer System Earns Tenth Consecutive SWIFTReady Gold Accreditation.

OMAHA, Neb. -- ACI Worldwide (Nasdaq:TSAI), a leading international provider of enterprise payment solutions, today announced that its market-leading ACI Money Transfer System[TM] has achieved the highest SWIFTReady accreditation for Payments for the tenth consecutive year. The Gold Label accreditation recognizes that the Money Transfer System satisfies SWIFT's highest requirements, and it is a tribute to ACI's decade-long support and commitment to SWIFT's standards, products and services.

"For the tenth consecutive year, we are pleased to award our highest accreditation, the SWIFTReady Gold label, to ACI Worldwide's Money Transfer System solution," said Victor Abbeloos, senior manager, marketing, at SWIFT. "Since the inception of the SWIFTReady program, ACI Worldwide has consistently demonstrated its ongoing commitment to satisfying the standards set forth by SWIFT. It is a pleasure to recognize this commitment with an impressive tenth SWIFTReady Gold certification."

SWIFT, the Society for Worldwide Interbank Financial Telecommunication, supplies secure messaging services and interface software to wholesale financial entities. Third-party financial applications, such as the ACI Money Transfer System, are either awarded SWIFTReady Silver or SWIFTReady Gold labels, depending on their level of compliance. Candidates for the SWIFTReady accreditation are evaluated on an annual basis to determine their ability to meet a wide range of SWIFT-specific criteria. The SWIFTReady Gold level of accreditation certifies that the Money Transfer System satisfied all SWIFT requirements across a wide range of criteria that are SWIFT-specific and re-evaluated on a yearly basis. The labeling also confirms that the Money Transfer System can be fully integrated into a SWIFT messaging environment.

With interfaces to SWIFT - as well as Fedwire, CHIPS, telex carriers, Fed Book Entry Securities and many international RTGS networks - the system is a single, integrated solution for domestic and international payments processing.
