ACI Money Transfer System Earns Eleventh Consecutive SWIFTReady Gold Accreditation

 “We are pleased to once again award our highest accreditation, the SWIFTReady Gold label, to ACI Worldwide’s Money Transfer System solution,” said Philippe Lecomte, manager, SWIFTSolutions Partner Management, SWIFT.  “Since the inception of the SWIFTReady program, ACI Worldwide has consistently demonstrated its ongoing commitment to satisfying the standards set forth by SWIFT.”     

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 ACI Money Transfer System is a multibank and multicurrency global payments processing and risk management system that provides continuous processing capabilities.  With interfaces directly to SWIFTNet services - as well as multiple RTGS and low value networks across the globe – the system is a single, integrated solution for domestic and international payments processing.  The ACI Money Transfer System for SEPA supports processing for transactions under the SEPA Credit Transfer and Direct Debit schemes, as well as the Euro Banking Association’s prieuro scheme and existing country-specific formats.

“ACI is dedicated to providing customers with robust payments solutions of the highest quality, technology, and functionality,” said Mark Vipond, president of the global product division at ACI.  “Obtaining the SWIFTReady Gold certification for the eleventh consecutive year underscores our dedication to our customers and validates our commitment to state-of-the-art products and technologies.”
