1. A wireless communication device, comprising:

  • a) a receiver and a transmitter;

    b) a substrate with an antenna thereon, said antenna receiving a first wireless signal and transmitting or broadcasting a second wireless signal;

    c) an integrated circuit configured to (i) process said first wireless signal and/or information therefrom, and (ii) generate said second wireless signal and/or information therefor, said integrated circuit comprising a continuity sensor, a memory, a first set of terminals electrically connected to said antenna, and a second set of terminals electrically connected to said continuity sensor, said second set of terminals being different from said first set of terminals; and

    d) one or more protection lines connected to said second set of terminals, the protection line(s) being configured to sense or determine a continuity state of a package or container on which the communication device is placed or to which the communication device is fixed or adhered,wherein;

    the memory includes one or more dynamic sensor bits configured to store a value corresponding to the continuity state of the container or package,the continuity state of the package or container is opened when at least one of the one or more protection lines is broken,the continuity state of the package or container is closed or sealed when each of the one or more protection lines is not broken,the one or more dynamic sensor bits 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 wireless signal communicates the value of the continuity state of the container or package.
