question: Provide a list of security measures implemented by payment gateway providers to ensure secure payment processing. Answer with at least 5 pieces of information in a bullet list, each containing a quoted term relevant to the security measure.
  
  * "Encryption"
  * "Tokenization"
  * "PCI DSS Compliance"
  * "Fraud Detection"
  * "Two-Factor Authentication"
answer: - "Encryption": Payment gateways use encryption protocols like SSL/TLS to protect sensitive data during transmission, ensuring that information such as credit card numbers is securely encoded.
  
  - "Tokenization": This process replaces sensitive payment information with non-sensitive tokens, reducing the risk of data breaches by ensuring that actual card details are not stored or transmitted.
  
  - "PCI DSS Compliance": Payment gateways adhere to the Payment Card Industry Data Security Standard, a set of security requirements designed to protect card information and maintain a secure transaction environment.
  
  - "Fraud Detection": Advanced fraud detection systems are implemented to identify and prevent unauthorized transactions by analyzing patterns and flagging suspicious activities.
  
  - "Two-Factor Authentication": This additional security layer requires users to provide two forms of identification before completing a transaction, enhancing protection against unauthorized access.
