Abstract

See full text

A Radio Frequency IDentification (RFID) electronic shelf apparatus according to the present invention includes electronic shelf units stacked and each configured to have a plurality of reader antennas, a reader configured to recognize the electronic shelf units individually or in a group in order to recognize a tag included in the electronic shelf unit, and a position detection processing unit configured to group the plurality of reader antennas, included in the electronic shelf unit, and to obtain position information about the electronic shelf unit on which the tag is stacked based on tagging information provided by the reader. Accordingly, there are advantages of stability and accuracy in the transmission of information, reduced configuration costs, and efficient store management by solving the shadow region of an electric wave due to the stacking of items within an electronic shelf and the close arrangement of the items.
