Payment technology and security
What is PCI DSS?
Direct answer
PCI DSS is the Payment Card Industry Data Security Standard, a set of technical and operational requirements intended to protect payment account data. It applies to entities that store, process, or transmit cardholder data, and to systems that can affect that environment’s security. Validation method and scope depend on the merchant’s acceptance channels, technologies, providers, and acquiring requirements.

Key facts
- PCI DSS is maintained by the PCI Security Standards Council.
- Compliance is ongoing, not a one-time certificate.
- Using a validated provider does not transfer every merchant responsibility.
What the standard addresses
Requirements cover secure systems, account-data protection, vulnerability management, access control, monitoring, testing, and security policy. The current official standard and supporting documents should be used.
Validation and scope
An acquirer or payment brand generally defines a merchant’s validation obligations. Hosted payment pages, point-to-point encryption, and outsourcing may reduce scope only when implemented and documented correctly.
When the answer changes
- Requirements and transition dates change by standard version.
- Ecommerce scripts and third-party integrations can affect scope.
Common mistakes
- Treating a questionnaire as the entire security program.
- Storing prohibited authentication data after authorization.
What to verify
- Inventory every payment channel and data flow.
- Confirm the required SAQ, scans, attestations, and deadlines with the acquirer.
