The second level of research is practical materials science, which is directed toward the materials and processes that will yield durable, wear-resistant, survivable, and environmentally acceptable materials for printing features on, or for adding relief to, banknotes. The final area of research is applied science and engineering, which should have the intent of devising methods for economically and reliably imprinting the required features at a scale commensurate with the production of durable banknote features.

The committee recommends thorough psychophysical studies to optimize the combination of length and height to permit reliable absolute judgment by banknote size. If a change in dimensions were to be made in U.S.

Application of the existing body of research to the optimum type of numerals and ratio of numeral-to-background areas for banknote denomination requires some development, and continued research into more long-term ideas, such as the effectiveness of fluorescence or scintillation in the areas occupied by the numerals, is recommended. Color The selection of effective colors for banknote denomination, as well as the degree of saturation required to ensure easy and accurate recognition by visually disabled individuals, is an area about which much is still unknown.

The committee recommends that the Treasury Department and the Federal Reserve stay apprised of the work going on overseas and of experiences with circulation of banknotes with venous types of tactile marks. As a result of the technical work discussed, raised-relief features could be developed and tested against sound technical guidelines.

banknote base paper could have significant impact on note durability and on the ability to incorporate certain counterfeiting deterrents, as well as robust aids to help visually disabled people. Devices The committee agrees that a desirable approach would be to permit virtually all visually disabled individuals, together with normally sighted persons, to denominate banknotes without the aid of devices.

It is important that advances in the various potentially relevant sciences and engineering disciplines be monitored and their relevance to potential Treasury Department or BEP interests or needs recognized. The committee supports the approach suggested in the National Research Council report on anticounterfeiting measures that the BEP or other appropriate body sponsor annual or semi-annual technical workshops (NRC, 1993)

Long-term research into advanced features, possibly leading to smart money, should be initiated as possible directions become evident from technology development. Advances in microelectronics, nanotechnology, molecular electronics, materials, photonics, and magnetics should not only be followed but also encouraged by supporting technical work that is focused on deriving very sophisticated but inexpensive, reliable, accurate, inconspicuous devices to assist visually disabled people in recognizing, denominating, and perhaps authenticating U.S.
