The Payment Application Data Security Standard (PA-DSS) is the global security standard created by the Payment Card Industry Security Standards Council (PCI-SSC). PA-DSS was implemented in an effort to provide the definitive data standard for software vendors that develop payment applications.
The standard aims to prevent developed payment applications for third parties from storing prohibited secure data including magnetic stripe, CVV2, or PIN. In that process, the standard also dictates that software vendors develop payment applications that are compliant with the Payment Card Industry Data Security Standards (PCI-DSS).
PCI-DSS is a combination of best practices and associated requirements covering security management, policies, procedures, network architecture, software design, and other protective measures. These requirements apply to all entities that store, process, and/or transmit cardholder data.
