Abstract: A system and method for passively determining and placing a stock item using an internet of things (IoT) tag is presented. The method includes receiving, during a predefined time window, data packets from a gateway, wherein the received data packets include at least a sensing signal from a plurality of IoT tags; identifying a first IoT tag from the plurality of IoT tags having a signal strength indicator above a predetermined threshold rank, wherein the first IoT tag is attached to a stock item; identifying the stock item, using a machine learning algorithm on the received data packets of the identified first IoT tag; and causing determination of a placement point to place the identified stock item.
