Payment Applications Data Security Standard (PA-DSS)

The Payment Application Data Security Standard (PA-DSS) is a set of security rules designed to ensure that payment software used by merchants securely handles cardholder information. It provides guidelines for developers to build applications that protect sensitive data from theft or breaches during authorization and payment processing. By following PA-DSS, software vendors help merchants reduce risks, comply with industry regulations, and safeguard customers’ payment details, promoting trust and reducing fraud in electronic transactions.
