As can be seen in Figure 3, there are five unique types of transactions: cash-out, cash-in, payment, transfer, and debit. Cash-out is the most frequent money laundering transaction, accounting for nearly 36% of all transactions. Cash-out is followed by payment (34%), cash-in (22%), transfer (8%), and debit (1%). As expected, most transactions are in the form of cash (70%), with the remainder made up of payments, transfers, and debit cards. As noted above, the average amount laundered per transaction is $159,000, with a standard deviation of $265,000. These results show that money laundering is usually done with large sums of money, though the amount washed in each transaction varies greatly^6,40.
