PCI Compliance
Adherence to security standards for organizations that handle credit card data.
What is PCI Compliance?
PCI compliance refers to meeting the Payment Card Industry Data Security Standard (PCI DSS), a set of security requirements designed to protect cardholder data. The standard includes 12 requirements covering network security, data encryption, access controls, monitoring, and security policies. Compliance levels (1-4) depend on transaction volume, with Level 1 merchants (over 6 million transactions annually) facing the most rigorous requirements including annual on-site audits.
Why It Matters
PCI compliance is mandatory for any business that accepts card payments. Non-compliance can result in fines of $5,000-$100,000 per month, increased transaction fees, and liability for fraud losses. Beyond penalties, a data breach can destroy customer trust and result in lawsuits. Most small businesses can achieve compliance through their processor's tools and annual self-assessment questionnaires.

Frequently Asked Questions
Most small merchants complete an annual Self-Assessment Questionnaire (SAQ) and quarterly network scans. Your payment processor typically provides tools and guidance to simplify this process.
You may face monthly non-compliance fees ($20-$100), higher transaction rates, and liability for any fraud or data breaches. Card networks can also revoke your ability to accept cards.
Using a PCI-compliant processor reduces your compliance burden but doesn't eliminate it. You're still responsible for how you handle card data in your environment.
