What is PCI DSS Compliance?
What Does PCI DSS Stand For?
PCI DSS stands for Payment Card Industry Data Security Standard. It was created by the PCI Security Standards Council, founded by major card brands including Visa, Mastercard and American Express, to enforce consistent data security standards globally.
Who Does PCI DSS Apply To?
PCI DSS applies to any organisation, regardless of size, that accepts or processes card payments.
This includes:
- ecommerce businesses
- call centres
- retail stores
- service providers
- businesses taking payments over the phone
Even if you do not store card data, PCI DSS still applies.
Why PCI DSS Matters
PCI DSS exists to protect cardholder data and reduce the risk of fraud and data breaches.
Without compliance, businesses face:
- financial penalties
- increased transaction fees
- reputational damage
- potential loss of card acceptance privileges
PCI Compliance Levels Explained
PCI DSS has four compliance levels based on transaction volume:
- Level 1: Over 6 million transactions annually
- Level 2: 1–6 million transactions
- Level 3: 20,000–1 million ecommerce transactions
- Level 4: Fewer than 20,000 ecommerce or up to 1 million total transactions
Each level determines how compliance is validated, from self-assessment questionnaires to full audits.
What Do Businesses Need to Do to Be Compliant?
To meet PCI DSS requirements, businesses typically need to:
- complete a Self-Assessment Questionnaire (SAQ)
- conduct vulnerability scans (where required)
- submit compliance documentation to their acquiring bank
- maintain secure systems and processes
The exact requirements depend on how your business handles card data.
What is a PCI DSS SAQ?
A Self-Assessment Questionnaire (SAQ) is a form used to demonstrate PCI compliance.
There are multiple SAQ types depending on how payments are processed, including:
- SAQ A: Fully outsourced payments
- SAQ A-EP: Ecommerce with partial exposure
- SAQ D: Full data handling environments
Choosing the correct SAQ depends on your payment setup.
What is Cardholder Data?
Cardholder data includes:
- card number (PAN)
- cardholder name
- expiry date
- service code
Sensitive authentication data (such as CVV and PINs) must also be protected and must never be stored after authorisation.
Does PCI DSS Apply to Phone Payments?
Yes. PCI DSS applies to all payment channels, including:
- phone payments
- online payments
- face-to-face transactions
Taking card details over the phone without secure systems increases risk and compliance complexity.
What Happens if You Are Not PCI Compliant?
Failure to comply with PCI DSS can result in:
- fines from card schemes
- liability for fraud losses
- costly forensic investigations
- increased merchant service charges
- reputational damage
How to Reduce PCI Scope
One of the most effective ways to simplify PCI compliance is to remove cardholder data from your environment entirely.
This can be achieved by:
- using hosted payment pages
- using pay by link solutions
- ensuring customers enter their own card details securely
Simplify PCI DSS Compliance
Understanding PCI DSS is the first step — reducing your exposure is the next. Modern payment solutions can remove card data from your systems entirely, helping you stay compliant without complexity.
