Before initiating a renewal, it is important to check if your Mantra fingerprint or Iris scanner requires a recharge.
- Connect your scanner to an Android device using an OTG cable.
- Launch the official Mantra RD Service App.
- Tap 'Capture Test' or 'Check Device Status'.
- If the app returns 'RD Service Expired' or Error 1001, your device requires an immediate online validity recharge.
