In-Person Verification (IPV) is a regulatory requirement that needs to be completed in order to get your KYC registered. It is absolutely required for NRIs, PIOs and Mariners, irrespective of where they are located.
Scripbox uses your video recording (face the camera for 5 seconds) as a way to do IPV.
While you are completing the registration process, the system will ask you to upload this video. In case you choose to skip this step, you will receive a separate email with the link to do your IPV.
