The World Bank has developed a computer program that assesses the authenticity of world currency suspected of being counterfeit. The program contains extensive profiles of the printing techniques and components of currencies of all major nations; such profiles include chemical composition of paper, density of ink, and details in the printing plates that are invisible to the naked eye. Counterfeiters, including the best counterfeiters known from history, cannot hope to reproduce all facets of a particular nation’s currency.
