Surface-printable RFID transponders

摘要

Radio frequency identification transponders comprises a polymer film as substrate for an antenna or a circuit chip. A printable layer is disposed on one surface of the polymer film. It comprises particulate pigment and film forming binder. An adhesive layer is disposed on the opposite major surface of the polymer film, and a cover is adjacent to the adhesive layer. Radio frequency identification (RFID) transponders have a printable surface and a polymer film having two major surfaces opposite to each other as substrate for an antenna or a circuit chip which is electrically connected. The antenna and the circuit chip are attached to one of the major surfaces of the polymer film. A printable layer is disposed on one surface of the polymer film. It comprises particulate pigment and film forming binder to provide the printable surface at the top side of the RFID. An adhesive layer is disposed on the opposite major surface of the polymer film. A cover is adjacent to the adhesive layer to cover the open surface of the adhesive layer.
