A package with electronic circuitry for use in monitoring the removal of items from a receptacle, such as medication tablets from a blister cavity. The package is assembled with a plurality of cards, including a blister card (20), a backing card (30), and a trace card (40). The blister card includes at least one protruding receptacle (29) having an open side. The backing card includes at least one breachable closed cell (32), mated to a blister card such that the closed cell spans across the open side of the receptacle. The trace card also includes at least one breachable closed cell (32) and circuitry (42), mated to the backing card so that the closed cells are aligned. In another embodiment the backing card may be a layer of conductive foil (62) and the trace card may include a dielectric overlay (64).
