Payment Card Industry (PCI) Data Security Standards (DSS)

Last updated: January 19, 2024
Audience: All UW

Maintaining payment security is required for all entities that store, process, or transmit cardholder data. Guidance for maintaining payment security is provided in PCI security standards. These set the technical and operational requirements for organizations accepting or processing payment transactions, and for software developers and manufacturers of applications and devices used in those transactions.
