Mantra RD Service for Android

Brief overview

Mantra RD Service is a free utility for scanning and storing biometric-linked 12-digit Aadhaar numbers issued by the Unique Identification Authority of India (UIDAI). It provides instant identity and address verification for authentication processes across India and supports streamlined electronic KYC (eKYC) workflows.

What “RD” signifies

The RD in the app’s name stands for Registered Device. That indicates UIDAI permits only Aadhaar-registered biometric devices to use this application’s features. The app can also interface with compatible fingerprint readers such as models supported by the MFS100 driver.

System requirements and initial setup

• A smartphone with the app installed.
• A biometric reader that has been Aadhaar-registered (or converted to a registered device).
• The Mantra Management Client installed on the same machine or device to complete device registration and compatibility steps.
• Required permissions granted to the app (contacts, location, etc.) so it can operate correctly and verify device status.

Quick steps to capture fingerprints

1. Install Mantra RD Service and the Mantra Management Client before attempting captures.
2. Launch the app and grant the requested permissions (contacts, location, and other prompts).
3. Confirm the biometric reader is recognized as an Aadhaar-registered device; the app verifies root device status on first run.
4. Tap the Capture Test button to open the MantraRDSample screen and enter the required details for fingerprint scanning.
5. Complete the scan and follow on-screen prompts to submit data for eKYC or authentication.

Role of the Mantra Management Client

The Mantra Management Client is required to convert supported public biometric devices into Aadhaar-registered devices. It handles device-level registration and ensures the RD app can communicate securely with the biometric hardware. Without this client, registration and successful fingerprint capture are unlikely.

Advantages and known issues

• Environmentally friendly: fully digital and paperless eKYC and authentication processes.
• Convenient: enables remote biometric verification without visiting an office or standing in queues.

• Lightweight: the app is simple and not resource-heavy.

• Reported connectivity issues: some users find the capture-test process occasionally fails because the device is not detected or loses connection.

• Dependency on registered hardware: the tool won’t work with unregistered biometric readers, so additional setup is required.

Final notes

When set up with a registered biometric reader and the Mantra Management Client, Mantra RD Service can significantly reduce time and effort for Aadhaar-based authentication and eKYC. However, be prepared to troubleshoot device connectivity if capture attempts fail.
