What is the Know Your Customer Process?
Know Your Customer (KYC) is a mandatory process used by banks, financial institutions, and other regulated entities. It is conducted to verify the customer’s identity.

In traditional or paper-based systems, customers submit physical copies of their identity and address. The customer should visit the bank, fund house, or KYC Registration Agency in person.
