Most countries have a central bank
or other office/agency/enterprise of a governmental nature that overlays the
payment systems process in that country.
The key to moving money into, out of, or through that country is to tap
into this system.
The
Federal Reserve System in U.S., with components such as the Automated Clearing
House, FedWire, and the Fed’s item settlement services, is an example of such a
system. The FedWire is a computer
network that connects the 12 Federal Reserve Banks with approximately 20,000
domestic financial institutions that are depository institutions whose accounts
are insured by the US government (for example, the Federal Deposit Insurance
Corporation or National Credit Union Share Insurance Fund).
