How does this skill help reduce my PCI audit scope?

The skill provides technical strategies like tokenization, iFrames, and Hosted Payment Pages that allow you to offload card data handling to processors, often reducing your scope to simpler assessments like SAQ A.

Can this skill help me choose the right SAQ?

Yes, it includes a detailed decision tree to help you identify which Self-Assessment Questionnaire (A, A-EP, B, C, D, etc.) applies to your specific business model and environment.

Is this updated for PCI DSS 4.0?

Yes, the skill includes the updated 12 requirements, increased password length requirements (12 characters), and modern MFA standards introduced in version 4.0.

What programming languages are covered in the examples?

The skill currently provides implementation patterns for C#/.NET and frontend web technologies (HTML/JavaScript), but the principles can be applied to any stack.
