The form is that the perpetrators of criminal acts try to hide or disguise the origin of assets that are the result of criminal acts in various ways so that the assets resulting from crime are difficult to trace by law enforcement officials so that they freely utilize these assets for both legal and illegal activities. Money laundering activities almost always involve banks because of the globalization of banks so that through the payment system, especially those that are electronic (electronic funds transfer), the proceeds of crime that are generally large amounts will flow or even move beyond national borders by utilizing the bank's confidential factors that are generally upheld high by banking.
