Abstract

A client computer with a scanner capable of scanning objects for a code. The client computer scans the object of interest and translates the code into a URL (Uniform Resource Locator) that specifies both a server computer and the location within the server of information that is relevant to the object. The client computer transmits the URL to the server computer, receives the information related to the object from the server computer, and communicates the information to the customer.

Claims

1. A method in a client computer system for retrieving a document, comprising the machine executed steps of:

scanning data encoded on an object;

creating a uniform resource locator (URL) from said scanned encoded data, wherein said URL identifies a first server connected to said client computer system via a network and a location of said document on said first server, and wherein said URL is created from information retrieved from a second server using said scanned encoded data as a key into said information;

transmitting said URL to said first server; and

receiving s aid document from said first server.

2. The method of claim 1 wherein said client computer system and said second server are the same computer system.

3. The method of claim 1 wherein said client computer system and said second server are different computer systems and said client computer system is connected to said second server via said network.

4. The method of claim 1 wherein said encoded data is encoded on said object as a bar code.

5. The method of claim 1, wherein said creating step further comprises using said scanned encoded data as a key into a database located in said second server, wherein said database contains said URL.

6. An apparatus in a client computer system for retrieving a document, comprising:

means for scanning data encoded on an object;

means for creating a uniform resource locator (URL) from said scanned encoded data, wherein said URL identifies a first server connected to said client computer system via a network and a location of said document on said first server, and wherein said URL is created from information retrieved from a second server using said scanned encoded data as a key into said information;

means for transmitting said URL to said first server; and

means for receiving said document from said first server.

7. The apparatus of claim 6 wherein said client computer system and said second server are the same computer system.

8. The apparatus of claim 6 wherein said client computer system and said second server are different computer systems and said client computer system is connected to said second server via said network.

9. The apparatus of claim 6 wherein said encoded data is encoded on said object as a bar code.

10. The apparatus of claim 6, wherein said creating means further comprises using said scanned encoded data as a key into a database located in said second server, wherein said database contains said URL.

11. A program product, comprising:

means for creating a uniform resource locator (URL) from encoded data scanned from an object, wherein said URL identifies a first server connected to a client computer system via a network and a location of a document on said first server, and wherein said URL is created from information retrieved from a second server using said scanned encoded data as a key into said information;

means for transmitting said URL to said first server;

means for receiving said document from said first server; and

signal bearing media bearing said scanning means, said transmitting means, and said receiving means.

12. The program product of claim 11 wherein said client computer system and said second server are the same computer system.

13. The program product of claim 11 wherein said client computer system and said second server are different computer systems and said client computer system is connected to said second server via said network.

14. The program product of claim 11 wherein said encoded data is encoded on said object as a bar code.

15. The program product of claim 11, wherein said creating means further comprises using said scanned encoded data as a key into a database located in said second server, wherein said database contains said URL.
