System and method for identifying transition points in a retail facility

1. A system for updating an inventory database as products move from a stockroom to a sales floor of a retail facility, the system comprising:

an array of RFID readers positioned at different locations about the retail facility, wherein the array of RFID readers is configured to read RFID tags associated with products, and wherein the array of RFID readers spans at least portions of the stockroom and the sales floor; and

a control circuit communicatively coupled to the array of RFID readers, the control circuit configured to:

receive, from one or more RFID readers of the array of RFID readers, identifiers, wherein the identifiers are associated with the RFID tags;

determine, based on the identifiers, a flow of RFID tags;

identify, based on the flow of RFID tags and without reference to a structural map of the retail facility, a transition point from the stockroom to the sales floor;

determine, based on an RFID read, that a product has passed through the transition point from the stockroom to the sales floor; and

update the inventory database to indicate that the product is located on the sales floor.

2. The system of claim 1 , wherein the transition point is identified based on one or more of types of products, a volume of products, a variety of products, and a quantity of items.

3. The system of claim 1 , wherein the transition point is located between two or more RFID readers in the array of RFID readers.

4. The system of claim 1 , wherein the transition point is associated with a physical passageway.

5. The system of claim 1 , wherein the transition point is not associated with a physical passageway.

6. The system of claim 1 , wherein the determination that the product has passed through the transition point is based on one or more of a received signal strength indicator (RSSI) value, an angle of arrival, a read rate, and an identifier of an RFID reader.

7. The system of claim 1 , wherein the control circuit is further configured to:

determine a location of the product; and

update the inventory database to include the location of the product.

8. The system of claim 1 , wherein RFID readers in the array of RFID readers are placed at ten to twenty meter intervals.

9. The system of claim 1 , wherein the control circuit is further configured to:

determine, based on the flow of RFID tags, that the flow of RFID tags differs from a normal flow of RFID tags in the retail facility;

wherein the identification of the transition point from the stockroom to the sales floor is based on the flow of RFID tags differing from the normal flow of RFID tags in the retail facility.

10. The system of claim 9 , wherein the normal flow of RFID tags is based on an expected movement of RFID tags based on customers traversing the retail facility.

11. A method for updating an inventory database as products move from a stockroom to a sales floor of a retail facility, the method comprising:

receiving, from one or more RFID readers in an array of RFID readers positioned at different locations about the retail facility, identifiers, wherein the identifiers are associated with RFID tags, wherein the array of RFID readers is positioned about the retail facility, and wherein the one or more RFID readers are configured to read RFID tags associated with the products;

determining, based on the identifiers, a flow of RFID tags;

identifying, based on the flow of RFID tags and without reference to a structural map of the retail facility, a transition point from the stockroom to the sales floor;

determining, based on an RFID read, that a product has passed through the transition point from the stockroom to the sales floor; and

updating the inventory database to indicate that the product is located on the sales floor.

12. The method of claim 11 , wherein the transition point is identified based on one or more of types of products, a volume of products, a variety of products, and a quantity of items.

13. The method of claim 11 , wherein the transition point is located between two or more RFID readers in the array of RFID readers.

14. The method of claim 11 , wherein the transition point is associated with a physical passageway.

15. The method of claim 11 , wherein the transition point is not associated with a physical passageway.

16. The method of claim 11 , wherein the determination that the product has passed through the transition point is based on one or more of a received signal strength indicator (RSSI) value, an angle of arrival, a read rate, and an identifier of an RFID reader.

17. The method of claim 11 , further comprising:

determining a location of the product; and

updating the inventory database to include the location of the product.

18. The method of claim 11 , wherein the RFID readers in the array of RFID readers are placed at ten to twenty meter intervals.

19. The method of claim 11 , wherein the array of RFID readers spans at least portions of the stockroom and the sales floor.

20. The method of claim 11 , further comprising:

determining, based on the flow of RFID tags, that the flow of RFID tags differs from a normal flow of RFID tags in the retail facility;

wherein the identifying the transition point from the stockroom to the sales floor is based on the flow of RFID tags differing from the normal flow of RFID tags in the retail facility.

21. The method of claim 20 , wherein the normal flow of RFID tags is based on an expected movement of RFID tags based on customers traversing the retail facility.
