The Bureau of Engraving and Printing (BEP) within the Department of the Treasury has issued a Request for Information (RFI) seeking innovative overt security features aimed at deterring counterfeiting of future U.S. currency. The BEP is particularly interested in technologies and materials that are not currently available in the commercial market or public domain, which are challenging to replicate and can be easily verified by the public without the need for external devices. This initiative is crucial for enhancing the security of U.S. currency, ensuring its integrity and public trust. Interested parties are invited to submit preliminary samples along with a brief technical description to Chris Dollberg by November 15, 2026, at 2:00 PM Eastern Standard Time, and should refrain from including any proprietary or sensitive information in their responses.
