The present invention relates to a system for detecting and communicating the position of a pusher assembly on a shelf. In an embodiment, a system includes a control module, a pusher assembly, and a laser scanner. The laser scanner is configured to transmit a swept beam to a mirrored reflective surface located behind the pusher assembly. The control module analyzes the laser beam at the laser scanner to detect the position of the pusher assembly on the shelf. In another embodiment, a system includes a control module, a pusher assembly, and an infrared transceiver that sends and receives infrared signals. The transceiver may be located behind the pusher assembly. The control module analyzes the infrared signals to determine the position of the pusher assembly on the shelf.
