Managing credit card payments requires strict adherence to security standards and best practices. Always comply with PCI DSS (Payment Card Industry Data Security Standard) requirements when handling credit card information. Use tokenization to replace sensitive card data with unique identifiers, reducing security risks.

Implement secure payment gateways like Stripe, PayPal, or Square that handle PCI compliance on your behalf. These services process payments without storing card details on your servers. Always use HTTPS for all payment-related communications and implement proper SSL/TLS certificates.

Regularly audit your payment processes and maintain detailed transaction logs. Implement fraud detection measures including address verification, CVV checks, and transaction monitoring. Provide clear refund and dispute resolution procedures. Keep payment systems updated with the latest security patches.
