Money laundering is the process of concealing or disguising the source of illegally obtained funds or assets. It is a criminal activity which is used to promote unlawful activities, such as fraud, drug trafficking, terrorism, and tax evasion. Money laundering typically involves three steps: placement, layering, and integration. In the placement step, the proceeds of criminal activities are introduced into the financial system. In the layering phase, the funds are moved around in a complex web of transactions to disguise the source of the funds. In the integration phase, the funds are re-introduced into the financial system and are used to purchase legitimate assets, such as real estate or vehicles. There are several types of money laundering: 1. Structuring: This involves breaking down large sums of money into smaller amounts to avoid detection by financial institutions. 2. Surfing: This involves using multiple individuals to conduct numerous small transactions to avoid detection by financial institutions. 3. Trade-Based: This involves using false invoices or other documents to disguise the true source of funds. 4. Shell Companies: This involves using offshore companies to disguise the source of funds. 5. Gambling: This involves using casinos or other gambling activities to launder funds.
