Abstract
A reading device adapted to read 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 reading device including: a housing adapted to be held by a user in use; a radiation source for emitting radiation from the housing such that it exposes at least one coded data portion; an image 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.
Claims56
A reading device adapted to read 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 reading device including:
- (a) a housing adapted to be held by a user in use;
- (b) a radiation source for emitting radiation from the housing such that it exposes at least one coded data portion;
- (c) an image sensor for sensing the at least one exposed coded data portion;
- (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
- wherein the coded data is indicative of a plurality reference points.
A method of reading an interface surface provided on a product, 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 method including:
- (a) holding a housing of a reading device such that radiation is emitted through an aperture in the housing;
- and,
- (b) directing the radiation at the product item such that it exposes at least one coded data portion, the reading device being responsive to:
- (i) sense the at least one exposed coded data portion;
- and,
- (ii) generate, using at least some of the sensed coded data, product identity data indicative of the identity of the product item
- wherein the coded data is indicative of a plurality reference points.
