Improving RFID traceability systems with verifiable quality

Purpose – The purpose of this paper is to develop an efficient tool to ensure traceability data entry based on RFID and improve the detection of fakes inside the supply chain.Design/methodology/approach – First, the authors put forward a secure traceability system with a cryptographic operator that improves efficiency, saves costs and is adaptable to all types of supply chains. Second, the authors implement the system in a food manufacturing company, show the compatibility of the system with the initial production chain and demonstrate its improvement.Findings – The authors have economically and technologically improved the detection of faked goods in the supply chain by means of a cheap and scalable system based on RFID.Research limitations/implications – The system has been tested in a manufacturing point of the supply chain, not in the supply chain as a whole. As traceability is additive in character, the results can be generalized and applied to each part of the supply chain.Practical implications – A...
