Payment gateways employ multiple security measures to protect transactions and customer data:
1. Encryption: Data is encrypted during transmission to prevent unauthorized access or tampering.
2. PCI DSS Compliance: Payment gateways follow the Payment Card Industry Data Security Standard, ensuring they meet stringent security requirements.
3. Fraud Detection: Advanced algorithms and machine learning are used to detect and prevent fraud.
4. Tokenization: Sensitive card information is replaced with unique tokens, adding an extra layer of security.
5. Secure Authentication: Multi-factor authentication and other secure login methods verify user identity.
