Transparent conveyor for check-out scanning
First Claim
1. A scanning device for scanning an interface surface provided on a product item, the interface surface having disposed thereon coded data indicative of an identity of the product item and of a plurality of reference points, each reference point corresponding to a respective location on the interface surface, the product item being provided in a sensing region, the scanning device including:
- (a) a beam generator for generating at least one scanning beam having a predetermined spectrum;
(b) at least one beam controller for directing the at least one scanning beam into the sensing region through a scanning surface, the scanning surface being transmissive to radiation of at least a portion of the predetermined spectrum;
(c) a sensor for sensing at least some of the coded data on the interface surface of the product item; and
(d) a processor for generating, using at least some of the sensed coded data, product identity data indicative of the identity of the product item and position data representing the position of a sensed reference point on the interface surface.
