PCI DSS stands for Payment Card Industry Data Security Standard.
PCI DSS is a set of policies, standards and procedures designed to maximise the security of credit, debit and cash card transactions protecting cardholders against the misuse of their personal information.
PCI DSS applies to every merchant, however small who processes credit or debit card information.
PCI DSS was created jointly in 2004 by four major credit-card companies:
Visa, MasterCard, Discover and American Express.
The aim of the standard is to protect any information, which could be used to produce a counterfeit card or generate a fraudulent online transaction, from falling into the wrong hands.
This information includes the card number, the expiry date, PIN, CVV numbers, plus details used in online transactions such as password, email address and user name. 
PCI DSS sets out a number of major objectives.
New research reveals that two thirds of U.K. companies still do not fully understand PCI DSS requirements, with 89% saying they are not compliant with the current standard and unsure whether they would achieve compliance with the new PCI DSS compliance deadline of September 2010 set by the two main card providers, Visa and MasterCard
