Method and system for confirming location of product within shelf using RFID

A system for confirming a location of a product using radio-frequency identification (RFID), the system comprising:

• a plurality of shelf areas;
• a location tag included in each shelf area and transmitting a location tag RFID signal;
• a reader included in each shelf area and reading the RFID signal;
• and
• an RFID server analyzing data read by the reader and including an operating system, a database for storing data read by the reader, an RFID middleware for analyzing and refining the data read by the reader, and an application for using the data refined and analyzed through the RFID middleware,
• wherein:
• the reader confirms whether or not the location tag RFID signal is received;
• the RFID server, in response to the reader receiving the location tag RFID signal, determines that no product is on the corresponding shelf area;
• the reader, in response to not receiving the location tag RFID signal, confirms whether or not a product tag RFID signal transmitted by a product tag included in the product is received;
• the RFID server, in response to the reader not receiving the location tag RFID signal and receiving the product tag RFID signal transmitted by the product tag included in the product, determines that the product is on the corresponding shelf area;
• the RFID server, in response to the reader not receiving the location tag RFID signal and not receiving the product tag RFID signal, determines that an error occurs in the reader;
• and
• wherein the reader located in the shelf area is prevented from receiving the location tag RFID signal transmitted by the location tag located in the shelf area when the product is located on the shelf area.
