Payment Application Data Security Standard (PA-DSS)

The Payment Application Data Security Standard (PA-DSS) is a set of security requirements established by the PCI Security Standards Council. It ensures that payment applications—software used to process credit card transactions—are designed to protect sensitive cardholder data. Developers follow these guidelines to prevent data breaches and fraud, helping merchants securely handle payment information. By adhering to PA-DSS, payment applications reduce the risk of cyberattacks and ensure compliance with industry security standards, ultimately safeguarding both businesses and customers during payment transactions.
