Radiant Systems' Investments in Credit Card Security Validated as 'Best Practices'; Independent Auditor Reviewed Convenience Store POS Under Visa's Cardholder Information Security Program.

ATLANTA -- Radiant Systems, Inc. (NASDAQ: RADS) announces that the latest version of its convenience store point of sale has achieved validation for Payment Applications Best Practices (PABP) under Visa's Cardholder Information Security Program (CISP) after a review of the system by independent auditor AmbironTrustWave, Inc.

Convenience and petroleum retailers using Radiant Point of Sale can have confidence that the system has been independently verified and that it meets the most stringent industry guidelines for protecting credit cardholder information. In an effort to prevent incidents of fraud and credit card data theft, Visa's CISP program defines industry best practices for security of cardholder data and includes requirements for encryption and storing of that data by payment applications, such as point-of-sale systems. Radiant Point of Sale is among the first convenience store applications to achieve validation under the program.

"Protecting the consumers' card data is the shared responsibility of retailers, card processors and payment systems providers," said Mark Schoen, president of Radiant's global petroleum and convenience retail division. "Radiant is committed to working with our clients and partners to ensure that together we can provide these assurances to the consumer."

"Radiant Point of Sale is not only safe, but also the fastest solution in the industry," said Mike Finley, vice president, global product marketing of Radiant's global petroleum and convenience retail division. "With less innovative point-of-sale providers, increased security and encryption can be detrimental to speed of service. But we've invested in a generation of products that improves both speed and security at the same time."

The Radiant Convenience Store Point of Sale is the latest software application in the Radiant product line to achieve PABP validation under Visa's CISP program.
