KYC, or Know Your Customer, is the mandatory process conducted by businesses and institutions to identify and verify the identity of the client when initiating the business relationship, and periodically over time.

eKYC, on the other hand, is the expression used to describe the digitalization and electronic conception of KYC processes. It represents the remote, paperless process that minimizes the costs and traditional bureaucracy typically associated with KYC processes, leveraging digital and online technologies for verification and identity checks.
