Abstract
An apparatus for managing an inventory of goods stored in multiple bins on a shelving system includes an RFID antenna disposed on an upper shelf of the shelving system. The RFID antenna communicates with RFID tags disposed above the upper shelf RF shielding is disposed between the RFID antenna and lower shelves. An RFID tag is attached to a bin configured to contain the goods. The RFID tag is encoded with information identifying the goods stored in the bin. An RFID reader performs scans to detect RFID tags disposed above the upper shelf. An inventory computer generates a bin detection confirmation message based on the RFID tag being detected by the RFID reader at least a first number of times during a predetermined detection period. The inventory computer also generates a product reorder message based on the RFID tag being detected by the RFID reader at least a second number of times during the predetermined detection period, wherein the second number of times is greater than the first number of times. The product reorder message includes the information identifying the goods stored in the bin.
