   • How It Works: Tokenization replaces your actual card number with a unique digital identifier (token) for each transaction.
   • Benefit: This ensures that your real card details are never shared with merchants or stored on your device, reducing the risk of card information theft.
2. Encryption:
   • How It Works: Mobile payment transactions are encrypted from end to end.
   • Benefit: Encryption protects the data as it travels from your device to the payment processor, preventing interception by unauthorized parties.
3. Biometric Authentication:
   • How It Works: Mobile payment apps often require fingerprint, facial recognition, or iris scan for authentication.
   • Benefit: Biometric authentication provides a strong layer of security, making it difficult for unauthorized users to access the payment app.
4. Secure Element (SE) or Trusted Execution Environment (TEE):
   • How It Works: Sensitive payment information is stored in a secure chip (SE) or a protected area of the device’s processor (TEE).
   • Benefit: This isolates payment information from the rest of the device, protecting it from malware and other security threats.
5. Two-Factor Authentication (2FA):
   • How It Works: Some mobile payment systems require a second form of verification, such as a one-time password (OTP) sent via SMS or email.
   • Benefit: 2FA adds an extra layer of security, ensuring that even if your device is compromised, transactions cannot proceed without the additional verification step.
6. Real-Time Monitoring and Alerts:
   • How It Works: Mobile payment systems often include monitoring tools that detect unusual or suspicious activity.
