Frequently Asked Questions

No. It is an independent security assessment. It can support PCI DSS assessments, but it is not PCI SSC validation, listing, or certification of the application.

The POS application and its agreed transaction environment, such as card data handling, local storage, communications, user access, and device configuration.

No. Hardware evaluation under PCI PTS is performed by PCI-recognized laboratories. Device configuration is included only where agreed in scope.

Yes. Testing normally runs in a lab or test environment with test cards, or in agreed windows with production-safe constraints.

Retesting of agreed findings verifies your fixes and records their updated closure status for auditors and customers. Retest scope is confirmed during scoping.
