R&D Hidden Machine-Readable Security Features - FY26 - (Request for Information)

Description: Proposed features may become distinctive counterfeit deterrents incorporated into the banknote or applied to the notes. An effective hidden machine-readable feature should be: 1. difficult to discover on a banknote even by subject matter experts. 2. difficult to elucidate the functionality or detection mechanism of the feature. 3. readable by a highly discriminating standalone detection system. 4. resistant to simulation or duplication, both in terms of material and response.
