PCI DSS Requirements for Ecommerce
Every business that accepts credit cards must comply with Payment Card Industry Data Security Standards, but ecommerce businesses face specific considerations. Card-not-present transactions handled through websites create technology requirements and vulnerabilities that differ from in-store processing.
PCI compliance levels depend on transaction volume. Most small ecommerce businesses qualify as Level 4 merchants with simplified compliance through self-assessment questionnaires. Higher-volume merchants face more rigorous requirements including external security assessments.
How your website handles payment data determines your compliance scope. If customers enter card information directly on your site, you have broader compliance obligations than if you redirect to hosted payment pages or use tokenization. The right architecture can significantly reduce compliance burden.
Annual compliance validation involves completing the appropriate self-assessment questionnaire and may require quarterly network vulnerability scans. Failure to validate compliance can result in fines, higher processing fees, or loss of processing privileges.
Reducing Ecommerce PCI Scope
Hosted payment pages shift most card handling to your processor, reducing your compliance scope dramatically. When customers enter card information on your processor's secure page rather than your website, you're not handling card data directly.
Tokenization replaces actual card numbers with tokens that have no value outside your payment system. Once a card is tokenized, you can store and use the token for recurring transactions without maintaining the card number itself. This reduces what you need to protect.
iFrame-based payment forms embed secure payment fields from your processor within your checkout page. The customer experience appears seamless, but the card data never touches your servers. This approach combines good user experience with reduced compliance scope.
Choosing the right SAQ matters for appropriate compliance validation. Different questionnaire types apply to different business models. Completing the wrong questionnaire provides false comfort and may not satisfy your processor's requirements.
