   • Possible Causes:
     • Poor fingerprint quality due to dry, dirty, or worn-out fingers.
     • Sensor dirt or scratches.
     • Device firmware issues.
     • Network connectivity problems.
   • Solutions:
     • Ensure the user’s fingers are clean and dry.
     • Clean the biometric sensor with a soft, lint-free cloth.
     • Update the device firmware if necessary.
     • Check the network connectivity and server availability.
2. Timeout Errors
   • Possible Causes:
     • Slow or unstable internet connection.
     • Server overload or downtime.
     • Configuration issues in the biometric device.
   • Solutions:
     • Verify that the internet connection is stable and meets the minimum speed requirements.
     • Retry during off-peak hours to avoid server overload.
     • Reconfigure the device settings as per the manufacturer’s guidelines.
