1. An electronic device having a radio frequency identification (RFID) tag comprising:

  • an RFID tag circuit including;

    an input/output (I/O) interface;

    a memory for storing data;

    a first path-controlling circuit for receiving a first signal via the I/O interface, receiving a second signal in a wireless manner, and outputting one of the first and second signals;

    a baseband circuit coupled to the first path-controlling circuit and the memory for processing signals outputted by the first path-controlling circuit, accessing data stored in the memory, and outputting an output signal; and

    a second path-controlling circuit coupled to the baseband circuit for outputting signals outputted by the baseband circuit via the I/O interface or in a wireless manner; and

    an integrated circuit coupled to the I/O interface for transmitting signals with the RFID tag circuit.
