Payment Card Industry Data Security Standard
The Payment Card Industry Data Security Standard (PCI DSS) is a set of comprehensive requirements for enhancing payment account data security and is intended to help organisations proactively protect customer account data.
The PCI security standards are technical and operational requirements that were created to help organisations that process card payments prevent credit card fraud, hacking and various other security vulnerabilities and threats. The standards apply to all organisations that store, process or transmit cardholder data.
