"Know Your Customer" (KYC) refers to the mandatory process of verifying a customer's identity to mitigate risks like fraud, money laundering, and terrorist financing. It involves gathering and verifying customer information to ensure they are who they claim to be and to assess the potential risks associated with their financial activities. KYC is a crucial part of broader Anti-Money Laundering (AML) and Counter-Terrorist Financing (CTF) efforts.
