Abstract: Radio-frequency identification (RFID) tags and labels are produced having customized variable imprinting. Sheets of paper are used to form a simple and inexpensive structure for supporting and protecting RFID transponders. The paper structure also serves as a surface for customized variable imprinting using laser printers. The structure includes a base sheet, a cover sheet upon which a laser printer applied image is formed by passing the sheet assembly through a print path of a laser printer, and a mask sheet having at least one window. The sheets form a protective pocket within the window for protecting an electronic circuit from the heat and pressure applied by the laser printer when printing an image on the cover sheet. After printing, the structure can be separated into multiple RFID tags or labels. Identification information is transmitted from the electronic circuits inside the protective pockets to an external receiver.
