## Abstract

A scanning device is provided which has a beam emitter for emitting a beam, a deflector for deflecting the beam to generate a raster scan pattern over a scanning patch on a product item, a sensor for receiving a reflected beam from the scanning patch and sensing from the reflected beam data encoded by coded tags printed on an interface surface of the product item, and a processor for determining a description of the interface surface and at least one region of interface surface. The data encoded by each tag includes an identity of the product item, an identity of the interface surface and the position of the respective tag on the interface surface. The processor determines the description from the sensed interface surface identity and determined the region from the determined description and at least one of the position of the sensed tag and a position of the scanning patch relative to the interface surface.

## Claims

### Claim 1

A scanning device comprising:
a beam generator for emitting a beam;
a deflector for deflecting the beam to generate a raster scan pattern over a scanning patch on a product item;
a sensor for receiving a reflected beam from the scanning patch and sensing from the reflected beam data encoded by coded tags printed on an interface surface of the product item, the data encoded by each tag including an identity of the product item, an identity of the interface surface and the position of the respective tag on the interface surface; and
a processor for determining a description of the interface surface from the sensed interface surface identity and at least one region of interface surface from the determined description and at least one of the position of the sensed tag and a position of the scanning patch relative to the interface surface.

### Claim 2 (depends on 1)

A scanning device according to claim 1, further comprising a beam controller for selectively providing the scanning patch at one of a number of positions in a sensing region.

### Claim 3 (depends on 1)

A scanning device according to claim 1, further comprising a beam controller for directing the beam along at least a selected one of a number of patch beam paths.

### Claim 4 (depends on 3)

A scanning device according to claim 3, wherein each patch beam path extends into a sensing region at a respective angle.

### Claim 5 (depends on 3)

A scanning device according to claim 3, wherein the sensor is adapted to sense the reflected beam from the product item along the selected patch beam path.

### Claim 6 (depends on 1)

A scanning device according to claim 1, wherein the data encoded by the tags is redundantly encoded and the processor uses the redundantly encoded data to detect one or more errors therein.
