A wireless (e.g., near field or RF) communication device includes a receiver and/or transmitter (190), a substrate with an antenna (20) thereon, an integrated circuit (30), and one or more protection lines (32, 34). The antenna receives or transmits or broadcasts wireless signals. The integrated circuit has a first set of terminals electrically connected to the antenna. The protection lines sense 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, and are electrically connected to a second set of terminals of the integrated circuit different from the first set of terminals. |
