Hand-held laser scanning device for scanning a product item
First Claim
1. A hand-held laser scanning device for scanning an interface surface provided on a product item, the interface surface having visible information relating to the product item and a plurality of tags disposed thereon, each tag containing coded data indicative of an identity of the product item and a plurality of locations on the interface surface, and at least some of the tags being coincident with the visible information, the scanning device j comprising:
- (a) a housing;
(b) a laser for emitting a scanning beam from the housing and exposing at least one of the plurality of tags when the product item is provided in a sensing region;
(c) a sensor for sensing the coded data contained in the at least one exposed tag; and
(d) a processor for determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item and location data indicative of a location of the exposed tag on the interface surface.

Abstract
A laser scanning device for scanning an interface surface of a product item is provided. The interface surface has visible information relating to the product item and a plurality of tags disposed thereon. Each tag contains coded data indicative of an identity of the product item and a plurality of locations on the interface surface. At least some of the tags are coincident with the visible information. The scanning device comprises: (a) a housing; (b) a laser for emitting a scanning beam from the housing; (c) a sensor for sensing the coded data contained a tag exposed by the scanning beam; and (d) a processor for determining, using the sensed coded data, product identity data indicative of the identity of the product item and location data indicative of a location of the exposed tag on the interface surface.

15. A method of scanning an interface surface provided on a product item, the interface surface having visible information relating to the product item and a plurality of tags disposed thereon, each tag containing coded data indicative of an identity of the product item and a plurality of locations on the interface surface, and at least some of the tags being coincident with the visible information, the method comprising the steps of:
-
(a) holding the scanning device;
(b) activating the scanning device to thereby cause a scanning beam to be emitted from the housing, the scanning beam being directed in first and second orthogonal directions to thereby generate a raster scan pattern over a scanning patch; and
,(c) positioning the product item in a sensing region, such that the scanning patch exposes at least one of the plurality of tags, the scanning device being responsive to;
(i) sense the coded data contained in the at least one exposed tag; and
,(ii) generate, using at least some of the sensed coded data, product identity data indicative of the identity of the product item and location data indicative of a location of the exposed tag on the interface surface. - View Dependent Claims (16)

17. A system for scanning a product item, said system comprising:
-
a product item having an interface surface, the interface surface having visible information relating to the product item and a plurality of tags disposed thereon, each tag containing coded data indicative of an identity of the product item and a plurality of locations on the interface surface, wherein at least some of the tags are coincident with the visible information; and
a hand-held scanning device comprising;
(a) a housing;
(b) a laser for emitting a scanning beam from the housing and exposing at least one of the plurality of tags when the product item is provided in a sensing region;
(c) a sensor for sensing the coded data contained in the at least one exposed tag; and
(d) a processor for determining, using at least some of the sensed coded data, product identity data indicative of the identity of the product item and location data indicative of a location of the exposed tag on the interface surface.
