There is provided a content use monitoring package and method of making the same. The package includes a cover layer followed by a blister card layer. The third layer comprises an electronic sensor monitoring tag connected to a rupturable layer imprinted with a conductive grid. The grid is printed on a non-conductive, non paperboard rupturable substrate and is aligned with associated blisters in the blister card. To ensure precise and reliable electrical continuity between the tag and grid they are connected by a low or zero insertion force flat flex connector which connection is also reversible. The tag includes re-usable electronic circuitry and power source. The fourth and bottom layer is a backing which contains a mechanism to tear open the package and remove the tag by unplugging the flex circuit connector. The tag can then be reused and the battery replaced as required.
