Cash Funnels 

A Cash Funnel is just as it sounds. It is allot of people sending small amounts of cash leading directly to a location. This is how to generate allot of money from very little. This is how most political campaign rally's are financed. Cash is also the "form of payment" that generate concerns on taxes and receipting. Cash is usually transferred through "the middle man" meaning financial institutions and our governments. Books need to be kept and finances have to be regulated.
