Finding Misplaced Items in Retail by Clustering RFID Data
In retail, products are organized according to layout plans, so-called planograms. Compliance to planograms is important, since good product placement can significantly increase sales. Currently, retailers are about to implement RFID installations consisting of smart shelves and RFID-tagged items to support in-store logistics and processes. In principle, they can also use these installations to implement planogram compliance verification: Each antenna is supposed to detect all tagged items in one location of the planogram. But due to physical constraints, RFID tags can be identified by more than one RFID antenna.
