RFId systems hold great potentials in enhancing supply chain performances. Some of the major retailers in the World (Wall Mart, Metro Group, Tesco) made sounding campaigns promoting the benefits they were able to attain. Despite the growing number of researches concerning RFId benefits, a study investigating their measurement in the supply chain context is still lacking. This paper proposes to associate qualitative RFId benefits identified in literature with corresponding measures by designing three tools: (1) an RFId oriented Performance Measurement System for the identification of all RFId related supply chain performance indicators on the base of the SCOR Model. (2) A benefits-processes-measures matrix linking the benefits identified in literature with SCOR model process to identify supply chain measures impacted by the RFId system implementation. (3) A reference framework summarizing benefits measures.
