ELECTROMAGNETIC SHIELDING MATERIAL

摘要

An electromagnetic shielding material includes a paper web and a conductive layer adhered to an adjacently positioned surface of the paper web. This arrangement defines a laminate structure that, when interposed between a receiving antenna of an RFID smart chip and a transmitting antenna of a signal generator, prevents the reading of the chip. A security device capable of electromagnetically shielding an RFID smart chip includes an electromagnetic shielding material having at least one conductive layer and at least one adjacently positioned substrate. A method of electromagnetically shielding an RFID smart chip includes providing and placing an electromagnetic shielding material proximate an RFID smart chip and preferably between the RFID smart chip and a transmitting antenna of an RFID signal generator.
