Patent ID: 7457007

Claim:
A laser scanning device adapted to scan an interface surface provided on a product item, the interface surface having disposed thereon or therein coded data portions at a plurality of locations on the interface surface, each coded data portion containing coded data indicative of an identity of the product item, an identity of the interface surface and the position of the coded data portion, the scanning device including: a laser for emitting at least one scanning beam, the scanning beam being directed in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch, the scanning patch being provided on the interface surface such that it exposes at least one coded data portion; a sensor for sensing the at least one exposed coded data portion; and a processor for: determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item; determining the identity of the interface surface; determining position data representing a position of the sensed coded data portion on the interface surface; determining a description of the interface surface using the determined identity; and identifying the at least one region from the description and the position data.
