Know Your Customer rules (1970-2001)
The Bank Secrecy Act of 1970 required US banks to keep records and report suspicious activity. The 2001 USA PATRIOT Act expanded those duties across a wider set of financial firms and pushed identity verification into account opening.
Banks built customer identification into onboarding, with documents and databases checked before an account opened.
Verifying the person became a precondition for the transaction, and the model spread internationally through the Financial Action Task Force.
Know Your Agent borrows the name and the structure: establish who the actor is before deciding whether the action is allowed.
