Abstract
A wireless (e.g., near field or RF) communication device, and methods of manufacturing and using the same are disclosed. The wireless communication device includes a receiver and/or transmitter, a substrate with an antenna thereon, an integrated circuit, and one or more continuity sensors. The antenna receives and/or transmits or broadcasts a wireless signal. The integrated circuit processes the wireless signal and/or information therefrom, and/or generates the wireless signal and/or information therefor. The continuity sensor(s) are configured to sense or determine the presence of a chemical or substance in the package or container, and thus 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. The continuity sensor(s) are electrically connected to a set of terminals of the integrated circuit different from the set of terminals to which the antenna is electrically connected.
