Mar 07, 2011—Many RFID pilots have proved that the technology can increase supply-chain visibility as well as optimize processes, but few studies have investigated the potential benefits to be derived from analyzing large amounts of RFID data. The Auto-ID Lab St. Gallen, in Zurich, analyzed item-level Electronic Product Code (EPC) data gathered during a retail apparel RFID trial, conducted from September 2007 to December 2008, at a Metro Group menswear department store in Germany.
During the trial, more than 150,000 tagged items were tracked by 60 RFID readers using 200 antennas installed on the sales floors and in the back rooms, at the escalators and elevators, on several shelves and in all 20 fitting rooms. The EPC RFID data was stored in an EPC Information Services (EPCIS) database.
Inventory visibility: Retailers can better distinguish between actual stockouts and in-stock items that are not available on the shelves.
Process execution: Tracking the movement of merchandise throughout the store can reveal unknown inefficiencies.
Product misplacement: Retailers can more easily identify merchandise that is located at the wrong display fixtures. The duration of misplacements also can be measured, so retailers can improve sales-floor tidying processes.
