Payment Card Industry Data Security Standard (DSS) compliance is required of all entities that store, process or transmit Visa cardholder data, including financial institutions, merchants and service providers. Visa’s programmes manage PCI DSS compliance by requiring that participants demonstrate compliance on a regular basis.

PCI DSS compliance
Security standards that benefit everyone.
Payment Application Data Security Standard (PA-DSS)
Visa strongly encourages payment application vendors to develop and validate the conformance of their products to the PA–DSS. PA–DSS compliant applications help merchants and agents mitigate compromises, prevent storage of sensitive cardholder data and support overall compliance with the PCI DSS. PA–DSS applies only to third–party payment application software that stores, processes or transmits cardholder data as part of an authorisation or settlement. In–house software applications are covered within a merchant or agent’s PCI DSS assessment.
