Abstract

A shopping system comprising a reading device is provided. The reading device is adapted to read an interface surface provided on a product item. The interface surface has coded data disposed thereon which includes, at a plurality of locations on the interface surface, a corresponding plurality of coded data portions. Each coded data portion is indicative of an identity of the product item and the location of the coded data portion. The reading device includes: (a) a radiation source for emitting radiation such that it exposes at least one coded data portion; (b) an image sensor for sensing the exposed coded data portion; and (c) a processor for determining, using the sensed coded data, product identity data and/or position data.

Claims

1. A shopping system comprising 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 and the location of the coded data portion, the reading device including:

(a) a radiation source for emitting radiation such that it exposes at least one coded data portion;

(b) an image sensor for sensing the at least one exposed coded data portion;

(c) a processor for determining, using at least some of the sensed coded data, at least one of;

product identity data indicative of the identity of the product item; and

position data indicative of the position of the sensed coded data portion on the interface surface and/or a position of the reading device relative to the interface surface.

2. The system of claim 1 wherein the reading device is a handheld device comprising a housing adapted to be held by a user.

3. The system of claim 2, wherein the housing includes:

(a) a grip for holding by the user; and

,

(b) a nose having an aperture for emitting the radiation and for receiving radiation reflected from product items in a sensing region.

4. The system of claim 2, wherein the housing is in the form of a pen housing.

5. The system of claim 4, wherein the reading device includes at least one force sensor coupled to a nib, and wherein the reading device is adapted to sense coded data in response to contact between the nib and the interface surface.

6. The system of claim 1, which is a shopping cart.

7. The system of claim 1, which is a checkout system further comprising a conveyor, said reading device being fixedly positioned to read coded data on product items being conveyed past said reading device.

8. The system of claim 1, wherein the coded data encodes an EPC associated with the product item, and wherein the processor determines the EPC.

9. The system of claim 1, wherein the product identity data distinguishes the product item from every other product item.

10. The system of claim 1, wherein the interface surface includes at least one region, the region including coded data indicative of an identity of the region, and wherein the processor determines the identity of the at least one region from at least some of the sensed coded data.

11. The system of claim 10, wherein the at least one region includes at least one coded data portion, and wherein the coded data portion is indicative of the region identity.

12. The system of claim 1, wherein the coded data is disposed over at least one of:

(a) substantially all of any one of;

(i) an entire product surface;

(ii) a packaging; and

,

(iii) a label;

(b) more than 25% of any one of;

(i) an entire product surface;

(ii) a packaging; and

,

(iii) a label;

(c) more than 50% of any one of;

(i) an entire product surface;

(ii) a packaging; and

,

(iii) a label; and

,

(d) more than 75% of any one of;

(i) an entire product surface;

(ii) a packaging; and

,

(iii) a label.

13. The system of claim 1, wherein the coded data is printed with infrared ink.

14. The system of claim 1, wherein the reading device further comprises a transmitter for transmitting at least one of the product identity data and the position data to a computer system.

15. The system of claim 1, further comprising the product item.
