The Basics

Core Concepts Explained Simply

PCI DSS stands for Payment Card Industry Data Security Standard. Think of it as a set of security rules created by major credit card companies to keep payment information safe. When someone buys from your Square online store, their credit card details need protection—that’s where PCI compliance comes in.

Square’s Role: Square acts as your payment processor, handling the technical aspects of accepting payments. They’re already PCI compliant, which means they’ve built strong security into their system. However, as a merchant, you still have responsibilities.

Key Terminology

Merchant: That’s you—the business accepting credit card payments
Payment Processor: Square, in this case—the company that handles the transaction
SAQ (Self-Assessment Questionnaire): A form you complete to verify your compliance
Cardholder Data: Credit card numbers, expiration dates, and security codes
PCI Levels: Categories based on how many transactions you process annually
