Know Your Customer (KYC) is a critical component of anti-money laundering (AML) measures and is used primarily in the financial sector, including banks and cryptocurrency exchanges. KYC involves gathering and verifying information about the identity of clients before establishing a business relationship. This process helps mitigate risks of illegal activity such as money laundering, fraud, and terrorist financing. The implementation of KYC regulations ensures that the identity of those engaging in financial transactions is confirmed through methods such as official identification documents, proof of address, and sometimes more advanced verification techniques.
