Norcross, Georgia, 09 Nov 2009

S1 Corporation (NASDAQ: SONE), a leading global provider of financial services and payments software solutions, today announced that Computer Services (CSVI) has chosen S1 to replace its legacy payments system.

CSI is recognised as an industry leader, offering service and software solutions to over 6 000 financial institutions and corporate entities. CSI decided to replace their legacy payments system with a proven open architecture to support their card issuing business. Further, because CSI manages hundreds of connections to external parties, they needed a software solution capable of processing a large cards base and supporting high transaction volumes.

S1 will provide CSI with an open-systems payments solution supporting card management and ATM driving, using its active/active high performance environment.

The S1 solution will:

* Manage online connections to ATMs, networks, card associations, host and settlement systems, and provide sophisticated monitoring of real time management information.
* Provide a browser-based portal from which CSI can configure a wide variety of services for their issuers, including card program management, stand-in options, card and account validation options, and PIN processing services.
* Provide a “bridge” approach to enable a phased migration from their legacy environment - a requirement for migrating CSI's over 450 card issuers.

S1's unique active/active option provides application-level synchronisation between two or more fully active and redundant servers, eliminating both planned and unplanned downtime and ensuring high availability to the end-user.

“In August 2008, we began an extensive evaluation of card services software providers,” said Larry Moore, CSI Vice-President of Card Services. “We wanted a partner whose business direction was aligned with ours, who offered a proven open architecture system with a cost-effective operating platform, and who gave us the ability to add non-card products in a high availability environment. S1 met or exceeded our evaluation criteria in every category.”

Moore continues: “S1's worldwide presence, strong management, experienced products teams, extensive open systems experience, and additional solutions in areas such as mobile banking, Internet banking, and voice response were also key strengths that influenced our decision.”

“When a decision is made by an organisation such as CSI to invest in financial services and payments software, it isn't just about the features and functions. It is about whether the company providing that software can be trusted with their client's reputation and brand,” said Francois van Schoor, President, S1 Payments. “We are proud to be selected as a partner for a company of the calibre of CSI. We look forward to a long and mutually rewarding relationship.”
