A scanning device is provided which has a beam emitter for emitting a beam, a deflector for deflecting the beam to generate a raster scan pattern over a scanning patch on a product item, a sensor for receiving a reflected beam from the scanning patch and sensing from the reflected beam data encoded by coded tags printed on an interface surface of the product item, and a processor for determining a description of the interface surface and at least one region of interface surface. The data encoded by each tag includes an identity of the product item, an identity of the interface surface and the position of the respective tag on the interface surface. The processor determines the description from the sensed interface surface identity and determined the region from the determined description and at least one of the position of the sensed tag and a position of the scanning patch relative to the interface surface.
