PCI DSS v4.0.1

Payment security rules apply to any system that stores, processes or transmits account data. An assistant can drag a new system into that scope with a single prompt. This starter keeps card data out of the prompt path and supplies evidence inputs for an assessment.

Scope is the whole argument in a payment assessment. A team that keeps account data away from the assistant keeps the assessed environment small. That goal sits behind every stage below.

Card data detection is the core of the request path. A payment aware redaction stage masks account identifiers. Three phrases stop a request outright: cardholder data, track data and a personal identification block. A run of thirteen to nineteen digits is treated as a card number.

Injection screening and a verified identity check run before that detection. The order matters, because a prompt must never disable the checks that follow it.

Returned text must hold 0.80 combined quality and 0.80 accuracy. No review step and no source check ship in this chain, so nothing pauses for a person by default.

Segmentation, key management, quarterly scanning and penetration testing remain infrastructure work under the standard. A qualified assessor evaluates the environment, and no starter shortens that. The final stage only shows that a call was evaluated.
