    Abstract: An integrated communication and capacitive sensing circuit and an interactive system using the same are provided in the present invention. The integrated communication and capacitive sensing circuit includes a microprocessor, a sensing electrode and a resonant circuit. The microprocessor includes a first input/output (I/O) pin and a second I/O pin. The sensing electrode is coupled to the first I/O pin of the microprocessor. The input terminal of the resonant circuit is coupled to the second I/O pin of the microprocessor, and the output terminal of the resonant circuit is coupled to the sensing electrode. When sensing the capacitance is performed, the first I/O pin of the microprocessor detects the charging/discharging state of the sensing electrode to determine the capacitive variation. When a data output is performed, the first I/O pin of the microprocessor is set to high impedance, and the second I/O pin of the microprocessor outputs or does not output a high frequency carrier according to a transmission data, wherein the resonant circuit amplifies the amplitude of the high frequency carrier.

    Abstract: A system for identifying identity (ID) and an ID card using the same are provided in the present invention. The ID card utilizes a specific ID reader to identify the ID of the ID card. The ID card includes a card case, a plurality of disposing positions for electrodes and at least a specific conductor electrode. The disposing positions are disposed in the card case. The specific conductor electrode(s) is/are disposed on at least one of the disposing positions according to the ID of the ED card. The specific card reader includes a flat panel sensor. When the ID card is close to the flat panel sensor of the card reader, the flat panel sensor senses the position of the conductor electrode(s) to determine the ID of the ID card.
