Title: Vapor detection of trafficking of contraband money: A discussion of technical feasibility

For every two pounds of cocaine smuggled into the US, drug traffikers are being forced to clandestinely ship three pounds of money back out for subsequent laundering. Based on tracer technology developed for validation of long-range atmospheric transport models and other commercial applications, it is shown that US currency can be tagged with a minute amount (about 1 ppm by weight of a bill) of perfluorocharbon tracer (PFT) material that is sufficient to last for about 30 years and yet provide a vapor emission rate suitable for detectability of modest caches of contraband money in vehicles at border crossings, on aircraft at international terminals, and in buildings. The cost of tagging is less than $5 per million bills; the taggant quantity should have no impact on the feel of a bill. The low emission rate would not allow detectability of usual amounts of money in typical scenarios, providing an essential degree of privacy, but extraordinary amounts would be detectable using specialized instrumentation and know-how not easily attainable but commercially in production; an example of sub-part-per-quadrillion detection of a proposed PFT taggant is demonstrated using a prototype commercial unit. An outline of a research and demonstration program to achieve this capability and details of the proposed tagging and detection procedures already indicate that the concept is technically feasible.
