FAQ: Why ask for requesting user's personal ID documents?
There's always someone ruining it for everyone else.
Criminals have long used electronic money transmission channels to conceal the source of fraudulently-obtained or stolen funds in order to fund illegal activities. As a result of this, the OCC and Federal Government require all entities facilitating the movement of money (that'd be us) to comply with the Bank Secrecy Act / Anti-Money Laundering (BSA / AML) laws.
These laws require us to know the identity of the person that is initiating the movement of money (that'd be you), irrespective of whether that money is coming from a company or personal account.
