1. An integrated circuit, comprising:

  • a) a receiver configured to process a first signal from an antenna;

    b) a transmitter configured to output a second signal to said antenna;

    c) a first set of terminals to be electrically connected to said antenna;

    d) a continuity sensor configured to determine whether a protection line electrically connected thereto is broken;

    e) a memory including one or more dynamic sensor bits and a plurality of ROM bits configured to store a unique identification code for a container or package; and

    f) a second set of terminals to be electrically connected to said continuity sensor,said second set of terminals being different from said first set of terminals, wherein;

    the protection line is configured to sense or determine a continuity state of the package or container,the continuity state of the package or container is opened when the protection line is broken,the continuity state of the package or container is closed or sealed when the protection line is not broken,the one or more dynamic sensor bits store a value corresponding to the continuity state of the container or package and is/are changed from a first value when the continuity state is closed or sealed to a second value when the continuity state is opened, andthe second signal communicates the value of the continuity state of the container or package.
