Payment Card Industry Data Security Standard—requirements for organisations handling card payment data.
PCI DSS (Payment Card Industry Data Security Standard) is a set of security requirements for organisations that store, process, or transmit payment card data. Created by major card brands, PCI DSS covers network security, data protection, access control, monitoring, and security policies. Compliance level depends on transaction volume—large merchants require external audits; smaller merchants can self-assess. Non-compliance risks fines, increased transaction fees, or loss of card acceptance ability.
Why It Matters
The DSC Perspective:
If you handle card payments, PCI DSS applies to you. Compliance requirements vary by transaction volume. Non-compliance carries financial penalties and reputational risk if breaches occur.
