Building Secure Payment Systems: PCI DSS Compliance in Practice
VViznetic EngineeringMarch 25, 202610 min read
Payments are where trust is won or lost. Supporting cards, UPI, wallets, and net banking across multiple gateways — while staying PCI DSS compliant — takes deliberate design.
Never touch raw card data
The single biggest compliance simplification is tokenization: card data goes straight from the client to the gateway, and our servers only ever see a token. That dramatically shrinks the audit scope.
Defense in depth
- TLS 1.3 everywhere, with strict security headers.
- Least-privilege access and full audit logging around payment flows.
- Idempotent payment intents to prevent double charges.
