The Payment Card Industry Data Security Standard (PCI DSS) is a worldwide information security standard defined by the Payment Card Industry Security Standards Council. The standard was created to help payment card industry organizations that process card payments prevent credit card fraud through increased controls around data and its exposure to compromise. The standard applies to all organizations that hold, process, or exchange cardholder information from any card branded with the logo of one of the card brands.
