Merchant risk & security.
As a merchant accepting card payments it's important to protect your business against fraud and give your customers confidence when purchasing from you.
Payment Card Industry Data Security Standards (PCI DSS).
What is PCI DSS?
Protection of card data is critical for all businesses. The PCI DSS is a set of comprehensive requirements to ensure increased cardholder data protection and forms industry best practice for those who process, transmit, store, or can impact the security of cardholder data.
What is cardholder data?
Any data held about a cardholder. For example: cardholder PIN, CVV (the three digit code on the back of a card), card number, expiry date, or the cardholder name.
What are the benefits of being PCI DSS compliant?
Compliance with PCI DSS is an obligation under your Westpac merchant agreement, however there are other benefits to being compliant:
- Provides a security standard.
- Decreased risk of data compromise.
- Increased consumer confidence and improved brand reputation.
- Peace of mind for you and your customers.
How does this affect my business?
PCI DSS compliance is required for all businesses and service providers that store, process, transmit or have access to cardholder data – or have systems that offer public internet access to the company – and extends across all payment channels.
Becoming PCI DSS compliant.
