A laser scanning device adapted to scan an interface surface provided on a
product item, the interface surface having disposed thereon coded data
which includes, at a plurality of locations on the interface surface, a
corresponding plurality of coded data portions, each coded data portion
being indicative of an identity of the product item, the scanning device
including: a housing adapted to be held by a user in use; a laser for
emitting a scanning beam 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, the scanning patch being
provided in the sensing region such that it exposes at least one coded
data portion; a sensor for sensing the at least one exposed coded data
portion; a processor for determining, using at least some of the sensed
coded data, product identity data indicative of the identity of the
product item.
