The present invention is directed to security systems that utilize electromagnetic radiation. The security system includes an authentication security document, an authentication system, and a process for authenticating security documents. The security document includes a document body with an RFID and body information pertinent to the security document. The RFID inlay includes a radiopaque material or other material that is opaque to ranges of electromagnetic radiation. The authentication system for secured documents includes an electromagnetic scanning device, a document with a document body, and the RFID device. The scanning device includes a secured device inlet suitable to accept the document body and a display that shows the results of the electromagnetic bombardment of the document body. The process for authenticating security documents includes positioning within the scanning device the security document to create a radiated image thereof that displays the inlay information.
