Abstract:
1. A product displaying system comprising: a plurality of product display shelves displaying a plurality of products, such that each respective product of the plurality of products has a respective RFID tag applied thereto, and such that each respective RFID tag stores a unique tag serial number; a plurality of antennas disposed on said plurality of product display shelves, each antenna of said plurality of antennas having a unique antenna number and each antenna of said plurality of antennas detecting the unique tag serial number from the respective RFID tag applied to a particular product of the plurality of products located within a predetermined area; human body sensors disposed at different positions on a front side of said plurality of product display shelves and detecting an approach of a human body; and a control computer including a tag-product ID registration table storing the unique tag serial number of each respective RFID tag and storing a unique product ID of each of the plurality of products, such that each stored unique tag serial number corresponds to each stored unique product ID, wherein said control computer receives the unique tag serial number of a respective RFID tag detected by said plurality of antennas and receives a detection time at which said human body sensors detect the approach of the human body, wherein said control computer detects at least one of (i) that a particular product of the plurality of products is picked up from a particular product display shelf of said plurality of product display shelves, and (ii) that a particular product of the plurality of products is returned to a particular product display shelf of said plurality of product display shelves, said control computer performing the detection by combining the unique tag serial number of the respective RFID tag and the unique antenna number of an antenna of the plurality of antennas that detected the unique tag serial number, wherein said control computer determines which direction the detected human body has moved based on a difference between the detection time of detecting the approaching human body obtained by each of said human body sensors, and wherein said control computer comprises a display device simultaneously displaying in parallel both a first bar indication and a second bar indication, such that the first bar indication represents, in time series, times at which a particular product of the plurality of products on a particular product display shelf of said plurality of product display shelves was picked up from the particular product display shelf and returned to the particular product display shelf, and such that the second bar indication represents, in time series, times at which the human body is detected by said human body sensors or times at which the human body is not detected by said human body sensors.
