Payment Security Standards: What Every Business Needs to Know

Why Payment Security Standards Exist

Payment security standards are the infrastructure of trust that enables the global payment system to function. Without them, the fraud, data breach, and consumer protection failures that inevitably emerge in any high-value data system would erode confidence in digital payments entirely. Understanding these standards — not just as compliance requirements but as tools that protect your business and your customers — is essential for any payment product owner.

PCI DSS

The Payment Card Industry Data Security Standard (PCI DSS) governs how card data must be handled, stored, and transmitted. The scope of your PCI compliance requirements depends heavily on how you integrate with payment systems. Businesses using hosted payment pages or payment provider SDKs that handle card data directly reduce their PCI scope significantly compared to those handling raw card data themselves. Version 4.0, effective in 2024, emphasizes continuous compliance over point-in-time assessment and increases requirements for authentication and access management.

Strong Customer Authentication

3D Secure 2 (3DS2) is the technical standard implementing Strong Customer Authentication (SCA) for online card transactions in regulated markets. Rather than the friction-heavy redirects of original 3DS, 3DS2 enables risk-based authentication that allows most low-risk transactions to proceed without additional user challenge while applying friction to high-risk transactions. Implementing 3DS2 correctly — rather than applying it uniformly — can improve conversion rates while meeting regulatory requirements.

The Role of Payment Processors in Compliance

Using certified payment processors significantly reduces the compliance burden on businesses. Certified processors handle card data storage, encryption, and transmission in compliance with PCI DSS. They manage 3DS2 authentication complexity. And they monitor for and report suspicious activity as required by card network rules.
