The standard for validating off-the-shelf payment applications used in authorization and settlement is:

• A. PCI PTS
• B. PCI P2PE
• C. PA-DSS
• D. PCI DSS

Answer: (C)

This is about ensuring that commercially available payment software used to process transactions is validated for secure handling of card data. Payment applications that merchants buy off-the-shelf and use in the authorization and settlement flow must meet security requirements so they don’t introduce PCI DSS risks on their own. The PA-DSS standard is designed for exactly this: it certifies third-party payment applications to ensure they handle data securely, don’t store sensitive full track data after authorization, and integrate with processors in a PCI-compliant way. This helps merchants deploy these apps with confidence that the software itself won’t undermine PCI compliance, without needing to audit every line of code themselves. In contrast, PCI PTS is focused on securing the hardware and PIN-entry devices, ensuring they resist tampering and protect PIN data at the point of entry. PCI P2PE centers on encrypting cardholder data from the point of capture to the processor, protecting data in transit. PCI DSS is the overarching set of requirements for protecting card data across the entire environment, but the specific validation of off-the-shelf payment applications used in authorization and settlement is PA-DSS.
