    Abstract: A radio frequency identification device (100, 200, 300, 350, 400, 500, 700) includes a substrate member (110) having a first surface (109) and a second surface (111). Disposed on the first surface of the substrate member are a first antenna element (112) and a second antenna element (114). The first and second antenna elements are electrically isolated from each other and are coupled to two separate pads on an integrated circuit (116, 116'). The integrated circuit includes a power circuit (814) that produces a supply voltage for electronics on the integrated circuit in response to voltages coupled over the air to the pads on the integrated circuit via the first and second antenna element. Adhesive (118) is applied on the first surface of the substrate, the first and second antenna elements and the integrated circuit for securing the tag to a person or thing.

    Abstract: A contactless programmable electrostatic RFID apparatus (101, 102) that is cost-effective, has high manufacturability, and can be easily packaged for a wide range of applications is presented. Under the present invention, following an exciter signal, a data reader/encoder (101) transmits a write mode data sequence to communicate to a transponder (102) whether to enter in to write mode. The modulated write mode data sequence further provides instruction, data, and memory address information for the transponder to use in writing data into its memory. Conversely, the transponder interprets the absence of such write mode data sequence to mean that read mode is desired. Accordingly, read mode is the default mode.
