Latest initiative from Postilion transforms ATM driving and improves service performance levels

Norcross, GA, US and London, United Kingdom – 14 April 2008 – Postilion, a leading provider of software solutions for self-service banking and payments and a division of S1 Corporation (NASDAQ: SONE), today announced the launch of enhancements to its ATM Driving solution. The Postilion ATM Driving solution can now be deployed in an active/active environment, ensuring higher ATM network availability while maintaining financial transaction integrity.

In an active/active Postilion environment, two production systems process transactions simultaneously across the entire ATM estate. Traffic from some ATMs is routed to one Postilion system, while other ATMs send transactions to the second Postilion system. This allows financial institutions to intelligently spread transaction loads across two systems based on operational requirements. The Postilion active/active approach has already proven to be extremely beneficial to large multi-lane retailers. By deploying the Postilion ATM Driving solution in an active/active environment, financial institutions now have the ultimate EFT high availability solution for their ATM networks.

“Previously, Postilion ensured ATM network availability with standard disaster recovery options. Enhanced with active/active capability, the Postilion ATM Driving solution now maximizes ATM uptime and minimizes back-office operational impact due to unplanned failures, thus providing improved operational efficiency, ROI, and a higher level of customer satisfaction,” comments Eben Esterhuyse, Product Manager, Postilion.

Additionally, if deployed with the correct network infrastructure, an active/active Postilion ATM Driving system can function as a disaster recovery solution. During unplanned downtime due to failure at either site, whether the failure is a communications, network, server, or other data center disruption, both servers are capable of handling 100% of the transaction load, thus maintaining online transaction processing integrity. A further advantage of an active/active Postilion deployment is that planned downtime, including scheduled server maintenance such as software and database upgrades, can be performed at one site with no downtime at the other site. From a cardholder’s perspective, banking service will not be interrupted.
