Abstract

A system for decoding an encoded symbol character associated with a product is provided. The system includes a scanning apparatus comprising a first scan source disposed within a housing, and a second scan source disposed within the housing. The second scan source comprises an operating technology distinct from an operating technology of the first scan source. The first scan source is adapted to output a first scan data set, and the second scan source is adapted to output a second scan data set. At least one of the first scan data set and the second scan data set comprises product bar code scan data.

Claims

1. A system comprising:

memory for storing data;

a laser scanner for outputting a first data set comprising barcode data;

an image sensor for outputting a second data set comprising barcode data; and

a central processing unit for executing a decoding process by combining the first data set and the second data set.

2. The system of claim 1, wherein the decoding process executed by the central processing unit comprises stitching the first data set and the second data set.

3. The system of claim 1, wherein:

the first data set comprises barcode data from a product barcode;

the second data set comprises alphanumeric characters associated with the product barcode; and

the central processing unit is configured for executing optical character recognition software and for comparing the barcode data from the product barcode with the alphanumeric characters associated with the product barcode.

4. The system of claim 1, comprising a radio frequency identification reader for outputting a third data set.

5. The system of claim 4, wherein:

the third data set comprises an electronic product code; and

the central processing unit is configured for executing a decoding process by combining the first data set, the second data set, and the third data set.

6. The system of claim 1, wherein:

the first data set comprises barcode data from a product;

the second data set comprises color images associated with the product; and

the central processing unit is configured for comparing the barcode data from the product with the color images associated with the product.

7. The system of claim 1, wherein:

the first data set comprises barcode data from a product;

the second data set comprises pattern images associated with the product; and

the central processing unit is configured for comparing the barcode data from the product with the pattern images associated with the product.

8. The system of claim 1, comprising a weight scale module for outputting a third data set comprising a weight associated with the product, wherein the central processing unit is configured for comparing the third data set with product weights associated with the first scan data set in the memory.

9. A system comprising:

a laser scanner for outputting a first data set;

an image sensor for outputting a second data set; and

a central processing unit for executing a decoding process by combining the first data set and the second data set.

10. The system of claim 9, wherein the decoding process executed by the central processing unit comprises stitching the first data set and the second data set.

11. The system of claim 9, wherein:

the first data set comprises barcode data from a product barcode;

the second data set comprises alphanumeric characters associated with the product barcode; and

the central processing unit is configured for executing optical character recognition software and for comparing the barcode data from the product barcode with the alphanumeric characters associated with the product barcode.

12. The system of claim 9, comprising a radio frequency identification reader for outputting a third data set.

13. The system of claim 12, wherein:

the third data set comprises an electronic product code; and

the central processing unit is configured for executing a decoding process by combining the first data set, the second data set, and the third data set.

14. The system of claim 9, wherein:

the first data set comprises barcode data from a product;

the second data set comprises color images associated with the product; and

the central processing unit is configured for comparing the barcode data from the product with the color images associated with the product.

15. The system of claim 9, wherein:

the first data set comprises barcode data from a product;

the second data set comprises pattern images associated with the product; and

the central processing unit is configured for comparing the barcode data from the product with the pattern images associated with the product.

16. The system of claim 9, comprising a weight scale module for outputting a third data set comprising a weight associated with the product, wherein the central processing unit is configured for comparing the third data set with product weights associated with the first scan data set in a memory.

17. A system comprising:

a laser scanner for outputting a first data set;

an image sensor for outputting a second data set; and

a central processing unit for executing a decoding process comprising stitching the first data set and the second data set.

18. The system of claim 17, wherein:

the first data set comprises barcode data from a product barcode;
