1. An active capacitive coupling RFID system, comprising:

  • (a) at least one reader, wherein the reader is configured to transmit modulated or unmodulated RF electrical signals and to receive and decode data transmitted by a transponder;

    (b) at least one active capacitive coupling RFID transponder comprising;

    (i) at least one integrated circuit, which is arranged to store a code comprising information and which is configured to generate, modulate and to transmit an RF carrier on LF or HF RFID frequency that comprises the stored code to the reader on a capacitive coupled communication channel;

    (ii) at least one antenna configured to receive electric signal via capacitive coupling from the at least one reader, and transmit the transponder code comprising information; and

    (iii) at least one power source for providing energy to the at least one integrated circuit and the transponder transmission; and

    (c) at least one data processing device for processing the data received from the reader.
