How to comply with PCI DSS payment security

Taking cards means PCI DSS obligations. The safe path: never touch raw card data, use a compliant processor, serve everything over HTTPS, never store card numbers, and complete your SAQ.

Step by step

Work through these — each is a place compliance is won or lost. PayProof's checker verifies every one for you in about a minute.

  1. How is card data handled?
  2. Is the entire site served over HTTPS?
  3. Do you avoid storing full card numbers / CVV?
  4. Have you completed your annual SAQ (self-assessment)?
  5. Is your checkout software & plugins kept updated?
  6. Is admin access protected with strong auth / MFA?
