The Bureau of Engraving and Printing (BEP) is issuing a Request for Information (RFI) to explore device-assisted security features for future U.S. currency. The objective is to identify innovative technologies and materials that enhance security against counterfeiting while remaining accessible for public authentication through low-cost devices such as optical filters, magnifiers, or cell phones. This initiative is crucial for maintaining the integrity of U.S. currency and ensuring public confidence in its security features. Interested parties are invited to submit preliminary samples and technical descriptions by November 15, 2026, at 2:00 PM Eastern Time, with all associated costs borne by the submitter. For further inquiries, contact Kevin Ibershoff at kevin.ibershoff@bep.gov or Falcon Albino at falcon.albino@bep.gov.
