Mantra Device Not Working in Mobile
Mantra biometric devices, such as the MFS100 and MFS110, are widely used for Aadhaar authentication and other secure identity verifications. However, users often encounter issues when connecting these devices to mobile phones. This guide provides a step-by-step approach to diagnosing and resolving the most common problems, ensuring your Mantra device works smoothly with your mobile.
Common Issues When Connecting Mantra Device to Mobile
- Device not detected or "not connected" error
- RD Service app not recognizing the device
- "Device not ready" or similar status messages
- Errors after Android updates
- Issues with OTG connection
- RD Service validity or registration errors
Step-by-Step Troubleshooting Guide
1. Check Device Compatibility
Ensure your mobile device supports OTG (On-The-Go) and is compatible with Mantra devices. Not all smartphones or tablets are suitable, especially for Aadhaar authentication.
2. Install or Update Mantra RD Service App
- Download the latest Mantra RD Service app from the Google Play Store.
- Uninstall any older versions or the Mantra Management Client app to avoid conflicts.
- Grant all necessary permissions when prompted.
3. Enable OTG Functionality
Go to your mobile’s settings and enable OTG support. This is essential for detecting the Mantra device.
4. Connect the Device Properly
- Use a good-quality OTG cable.
- Connect the Mantra device to the OTG cable, then plug the cable into your mobile.
- Wait for the "Device Ready to Use" prompt from the RD Service app.
5. Grant Permissions
Allow all permissions requested by the RD Service app. Denying permissions may prevent proper functionality.
6. Check RD Service Validity
- RD Service must be valid for Aadhaar authentication.
- If expired, renew the RD Service.
- You can check the status online.
7. Ensure Internet Connectivity
A stable internet connection is required for device registration and certain authentication steps.
8. Test the Device
Use the RD Service app’s built-in test function to verify device functionality after connection.

Additional Tips
- Avoid using rooted mobile devices for Aadhaar authentication – they may be blocked for security.
- Use original cables and accessories to avoid connectivity issues.
- Regularly update firmware and the RD Service app for compatibility with UIDAI requirements.
- If issues persist, try connecting the device to another mobile to isolate the root cause.
When to Seek Support

Provide:

For issues like "maximum limit exceeded" (device used on too many phones), email Mantra support to reset the usage log.
Summary
Most Mantra device issues on mobile can be resolved by:
