The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards designed to ensure that ALL companies that accept, process, store or transmit credit card information maintain a secure environment.
The Payment Card Industry Security Standards Council (PCI SSC) was launched on September 7, 2006 to manage the ongoing evolution of the Payment Card Industry (PCI) security standards with a focus on improving payment account security throughout the transaction process. The PCI DSS is administered and managed by the PCI SSC (www.pcisecuritystandards.org), an independent body that was created by the major payment card brands (Visa, MasterCard, American Express, Discover and JCB.). It is important to note that the payment brands and acquirers are responsible for enforcing compliance, not the PCI council. A copy of the PCI DSS is available here.
All merchants will fall into one of the four merchant levels based on Visa transaction volume over a 12-month period. Transaction volume is based on the aggregate number of Visa transactions (inclusive of credit, debit and prepaid) from a merchant Doing Business As (‘DBA’). In cases where a merchant corporation has more than one DBA, Visa acquirers must consider the aggregate volume of transactions stored, processed or transmitted by the corporate entity to determine the validation level. If data is not aggregated, such that the corporate entity does not store, process or transmit cardholder data on behalf of multiple DBAs, acquirers will continue to consider the DBA’s individual transaction volume to determine the validation level.
