What is PCI DSS?

PCI DSS is the Payment Card Industry Data Security Standard, and this is a worldwide standard that was set up to help businesses process card payments securely and reduce card fraud. The way it does this is through tight controls surrounding the storage, transmission and processing of cardholder data that businesses handle. PCI DSS is intended to protect sensitive cardholder data.

There are 12 high level requirements, and they fall into the six categories below:
