The paper contains a summary of the actual work developed to test the ability of radio technologies to perform traceability at different food companies in a variety of sectors: wine, fish, and meat. Each pilot experience is explained, with special emphasis on the radio segment implemented by RFID technologies and sensors, whether connected by wired or as elements of a wireless sensor network. The application of the new RFID-based system at the three investigated sectors, and the return on investment that the companies could obtain by its usage, are the core of the paper.enfrom farm to forkRadiofrequency identificationRFIDwireless sensor networksfood technologysupply chain managementtraceabilityJournal articleIEEE Antennas and Propagation
