KYC stands for Know Your Customer. It is a procedure that allows banking or financial organizations to verify the identity of customers and to ensure their compliance with the regulations in force. This procedure allows to fight against money laundering & terrorism financing, identity theft, and ensures compliance with tax regulations, laws and regulations related to the fight against corruption, and the protection of customers' interests. As an extension of the KYC concept, we find the term KYB for Know Your Business, which means in French "connaitre son entreprise". It is the same identity verification procedure, but applies to companies or legal entities.
