Abstract
A device for detecting the removal of a product from a packing system by an electronic unit. The products are arranged in individual bags which are sealed by a sealing film that can be perforated so as to remove a product from a bag. The device has a combination of layers including at least one supporting plate and a coating layer which is applied thereto. The combination of layers is connected to the packing system in such a way that the coating layer faces the sealing film. The coating layer is provided with individual strip conductors, each of which runs across an area that is assigned to a bag and is electrically interrupted when a product is removed from the respective bag. The supporting plate includes openings, each of which is assigned to a bag. A product which is removed from a bag is guided through the respective opening.
