Des Moines, Iowa (10/8/08)--The Members Group (TMG) announced today that it has joined the Payment Card Industry (PCI) Security Standards Council as a new participating organization. TMG will work with the council on PCI Data Security Standard (DSS) and other payment card data protection standards. The PCI DSS, endorsed by American Express, Discover Financial Services, JCB International, MasterCard Worldwide and Visa Inc., requires merchants and service providers that store, process or transmit customer payment card data to adhere to information security controls and processes that ensure data integrity. TMG will now have access to the latest payment card security standards from the Council, be able to provide feedback on the standards and become part of a growing community that now includes more than 500 organizations.
