PCI DSS stands for the Payment Card Industry Data Security Standard — the security rulebook that every business accepting card payments is expected to follow.
The major card brands — Visa, Mastercard, American Express, Discover, and JCB — created it to keep cardholder data safe from theft and fraud.
In one line: it’s the standard that keeps your customers’ card data safe.If you accept, process, store, or transmit card payments in any way — a countertop terminal, an online checkout, orders over the phone — PCI DSS applies to you.
There’s no business too small. A corner shop and a national retailer follow the same standard, scaled to how each one takes payments.
A card-data breach is expensive and damaging — and compliance isn’t optional: your bank and payment processor require it in your merchant agreement. The risks of ignoring it:
At its core, PCI DSS is 12 requirements grouped under 6 goals:
Most merchants show they’re compliant by completing a Self-Assessment Questionnaire (SAQ) once a year.
Which SAQ you use depends on how you take payments. You answer the questions that apply to your setup, gather a little supporting evidence, and submit it to your bank.
Picking the right SAQ means you only answer the questions that actually apply — often far fewer.You don’t have to figure this out alone. PCI-Nexus’s AI compliance agent scopes the right SAQ for your business, tells you exactly what applies, reviews your evidence, drafts your policies, and keeps you on track for your annual deadline.
