The Payment Card Industry Data Security Standard (PCI DSS) was created by the world's major credit card companies to protect customer data. The primary purpose of PCI is the protection of credit card data by reducing fraud and theft. PCI mandates that any merchants or service providers that handle, transmit, store or process information concerning the major credit cards, or related card data, are required to meet PCI standards or face penalties and/or severance by the credit card companies.
