From page 29...
... From the large list of possible features assembled by the committee, it is necessary to assess individual features and combinations of features to identify an optimum set that addresses all of these issues. One aspect of evaluating the proposed features is the development of operational meanings for the terms "recognize,""denominate," and "authenticate" and the determination of how well each feature performs these individual tasks.
From page 30...
... While the previous NRC study concentrated on optical or visible features to deter counterfeiting (NRC, 1993) , many of these attributes are also desirable in a feature to be used by visually disabled people to recognize and denominate U.S.
From page 31...
... The committee attempted to ensure that their list of recommended features provided overlapping coverage, so that each of the target groups would gain significant benefits from the redesigned banknotes if those recommended features were included. EVALUATION FRAMEWORK The committee developed four categories of evaluation criteria: population, function, technical success, and implementation success.
From page 32...
... For example, punching holes in banknotes, with the number of holes indicating denomination, would be assessed as a general concept in the technical success probability category, with some positive and some negative attributes. In the implementation success criteria category, the shape of the hole (for example, star-shaped, round, or oval)
From page 33...
... In the final two categories, technical success risk and implementation success risk, the criteria were not strictly ranked but were thought of as "high" weight or "low" weight. In the category for technical success criteria, the criteria considered to be most important were reliability of readings; ease of use; compatibility with security features; no requirement for a device other than a person's senses; and resistance to simulation.
From page 34...
... Ease of Use Feature is easy to use, especially in a situation where there is little time to examine money No Requirement for Device Applicability to Current Banknotes Compatible with Security Features Ability to Cocirculate Resistance to Simulation A person's senses can be used to evaluate the banknote, with no requirement for any device or machine Feature could be applied to currency presently in circulation or production without a redesign Feature is compatible with security features scheduled for implementation in the new currency design or recommended in the previous report (NRC, 1993) Notes can cocirculate with present notes without confusion, misidentification or compromise of automated moneyhandling machines Feature cannot be easily simulated or corrupted to indicate another denomination Table 3-4 Implementation Success Cntena Category Description of a Successful Feature Unit Cost Capital Cost Durability of Banknote Survivability of Feature Availability and Manufacturability Proven Banknote Technology Unit cost for note production (cost per note)
From page 35...
... The list of proposed features was organized generally into groups, including substrate based, edge modification, tactile marking, visual marking, and other. The proposed features were evaluated against the criteria described in these tables, using a "yes," "no," or "maybe" to indicate whether the feature met each criterion for success, whether it did not meet the criterion, or whether the committee was not able to evaluate whether the proposed feature met the criterion.
From page 36...
... When discussing many of the above points the committee formed the opinion that the technology could be helpful to people with normal vision using point-of-sale devices, cash accepting machines and automated cash registers, etc. This wider use may well increase the respective market for the units, bringing the prices down and driving the performance upwards.
