Dubai, United Arab Emirates - 11 May 2009 - Postilion, a leading global provider of payments software solutions and a division of S1 Corporation (NASDAQ: SONE), today announced that RAKBANK, the National Bank of Ras Al-Khaimah in the United Arab Emirates, has selected Postilion solutions to drive the bank's ATM network. For RAKBANK, the implementation of Postilion for ATM Owners and Deployers will bring operational improvements and help the bank deploy new ATM services faster and more efficiently.

RAKBANK chose Postilion to improve the bank's competitive differentiation in the UAE. The Postilion solution for ATM owners and deployers will replace the bank's existing ATM solution, providing real-time monitoring and a holistic view of all payment transactions on the ATM channel. Postilion's proven reliability and flexibility will allow RAKBANK to enhance system availability and will facilitate the introduction of additional banking services more quickly to satisfy new business demands.

Postilion's PA-DSS validated payments platform is regularly updated to address the latest data security standards. By choosing Postilion to be at the centre of its ATM network, RAKBANK will be able to more easily maintain compliance with payment card industry security regulations. Postilion's back-office application will provide automated reconciliation with the UAE's national EFT switch and provide consolidated reports on payments processing activity and performance to support RAKBANK's IT management decision-making.

"More and more banks and processors in the Middle East are relying on Postilion as we provide regional specialization and support coupled with international expertise and world-class payments software," said Francois van Schoor, President of Postilion Payments. "We look forward to supporting RAKBANK in their drive for exceptional customer service and operational excellence."
