PCI-DSS (Payment Card Industry Data Security Standard)

PCI-DSS is a security standard for organisations handling card payments, ensuring the protection of sensitive payment data. Compliance is required for merchants, payment processors, and service providers.

Applications

E-commerce:

Reduces fraud in online card payments by verifying the cardholder's identity

Banking and fintech:

Helps issuers and payment providers comply with Strong Customer Authentication (SCA) requirements.

Advantages

  • Enhanced security: Reduces unauthorised transactions by verifying that the genuine account holder is authorising the payment
  • Fraud prevention: Helps reduce chargebacks related to fraud.

Challenges

  • User Experience: Additional authentication steps can cause friction and increase checkout abandonment
  • Implementation complexity: Requires integration with card schemes and issuer systems.
