This skill provides specialized guidance for developers building payment systems that must adhere to Payment Card Industry Data Security Standards (PCI DSS). It offers production-ready patterns for data minimization, tokenization, and AES-256 encryption, while ensuring that sensitive elements like CVV or full track data are never stored. Whether you are using a third-party processor like Stripe or building a custom vault, this skill helps reduce compliance scope and prepares applications for security audits by enforcing best practices in access control, logging, and network security.
