PAYMENT INDUSTRY REFERENCE MATERIAL  Used in my work developing firmware for payment terminals

GENERAL

• The PCI Security Standards Council issues standards to be used in securing payment transactions within the Payment Card Industry.

DOCUMENTS.  Most, if not all, of the following documents were found in the documents library of the PCI Security Standards Council website:

• PCI SSC Data Security Standards Overview
  
• PCI DSS Quick Reference Guide
  
• Navigating PCI DSS is a PDF document that provides an overview of PCI DSS requirements.  The following is from the document's preface:
  "This document describes the 12 Payment Card Industry Data Security Standard (PCI DSS) requirements, along with guidance to explain the intent
  of each requirement. This document is intended to assist merchants, service providers, and financial institutions who may want a clearer
  understanding of the Payment Card Industry Data Security Standard, and the specific meaning and intention behind the detailed requirements to
  secure system components (servers, network, applications, etc.) that support cardholder data environments."
• PCI DSS - Requirements and Security Assessment Procedures
  
• The PCI DSS Self Assessment Questionaire (SAQ) provides the "tools" needed to perform a self-assessment for PCI DSS compliance.
  
• Glossary of terms for PCI DSS and PA-DSS
