Abstract

A system to monitor item placement and item movement on surfaces includes an identification system embedded in one or more surfaces and a computer. The identification system periodically scans the surfaces to generate data related to items placed on the surfaces. The data includes item type, item location on each surface, and number of items placed on each surface. The computer receives and processes the data to monitor item placement and item movement on the surfaces.

3. The system of claim 1, wherein the RF-ID system includes a set of inductor coils, including the first group of coils, embedded in the surfaces that are energized during the scanning.

4. The system of claim 3, wherein the RF-ID system includes one or more reader microprocessor units and RF-ID tag readers that generate the item-related data by selectively energizing the set of inductor coils.

5. The system of claim 1, wherein the scanning is continuous so as to provide item-related data that may be used to monitor item placement and movement on the surfaces in real-time.

6. The system of claim 1, wherein the surfaces are surfaces of one or more shelves.

7. The system of claim 1, wherein the computer provides a user interface that displays a graphical representation of one of the surfaces and the items on the surface.

8. The system of claim 1, wherein the items are products in a store or in a warehouse and the surfaces are the surfaces of one or more store shelves or warehouse shelves.

9. The system of claim 8, wherein the computer generates a message when the number of items placed on the surfaces of store shelves or warehouse shelves decreases below a predetermined threshold.

10. The system of claim 9, wherein the message is an out-of-stock message and the items are all associated with a specific item manufacturer name or item product name.

11. The system of claim 8, wherein the computer determines whether items are correctly placed on portions of the surfaces of warehouse shelves or store shelves assigned to carry the items by comparing the item location on the surfaces of the shelves with shelf assignment data.

12. The system of claim 11, wherein the computer generates a message when a number of items incorrectly placed on the surfaces of store shelves or warehouse shelves increases above a predetermined threshold.

13. The system of claim 8, wherein the computer processes the item-related data to determine an item placement on the surfaces of shelves that increases item sales.

14. The system of claim 8, wherein the computer generates a message when an event relating to item movement on the surfaces of shelves occurs.

15. The system of claim 14, wherein the event corresponds to an item being removed from the surface of a store shelf and neither bought nor put back on any shelves in the store for a predetermined amount of time.

16. The system of claim 14, wherein the event corresponds to items being moved from the surfaces of shelves in response to changing the price of the items.

17. The system of claim 8, wherein the computer provides the item-related data to a content based messaging network and updates the item-related data in real-time based on repeated scanning of the surfaces of the shelves.

18. The system of claim 17, wherein the item-related data is accessible to a manufacturer or a distribution center associated with the store or the warehouse.

30. The system of claim 1, wherein the RF-ID system is further configured to:

receive a second electronic indication of a physical size of items to be placed on a second portion of the surface of the shelf in which is embedded a second group of inductor coils, the second electronic indication being different from the first electronic indication, the second portion of the surface being different from the first portion of the surface, and the second group of inductor coils being different from the first group of inductor coils;
