A security system for paper or plastic-based items using chipless RFID

The purpose of this paper is to develop an innovative system which uses chipless RFID tags to protect sensitive paper/ polymer-based documents, such as intelligence agency reports, financial securities, envelopes, stamps, and banknotes. The significance of this project is vital as the expected outcome from this new system can be used to strengthen the security of important documents and banknotes and thus unauthorized copy and fraud can be identified and avoided. In order to achieve this, the idea of embedding or printing invisible RF reflecting fibers/ inks that are made of tiny chemical particles (having various magnetism), is designed and developed, by usage of a multi-frequency RFID reader that will beam the waves and capture the attenuation from the transponder in the form of analog signals and digital codes, then compared with a database that will provide authenticity.
