From Automatic Identification And Data Capture (Aidc) To “Smart Business Process”: Preparing For A Pilot Integrating Rfid, S. F. Wamba, E. Lefebvre, Y. Bendavid, L.. A. Lefebvre

Dr Samuel Fosso Wamba

This paper examines the underlying logic behind the rules configured in a RFID middleware to support “smart business processes” in one retail supply chain. Through a detailed investigation of the underlying business processes, we will demonstrate how businesses rules can be defined, configured and refined in a RFID middleware. The results confirm that RFID technology is not a “Plug and Play” solution. RFID middleware configuration will require a high level of customization. Finally, this study allows the improvement of our understanding of the real potential of RFID technology in the supply chain context.
