Neural networks are currently used by financial institutions to recognize money laundering and credit card fraud, but also have its place in the war on terrorism. More than 11.2 million trucks entered the United States from Mexico or Canada last year, and instead of inspecting each one, a computer can be used to pick out suspicious hauls, which would warrant greater examination than the rest.
