This paper presents the current status and future trends of sensor technologies for food products traceability, specifically for systems devoted to be applied in the cold storage and refrigerated transport of horticultural products. The combination of wireless technologies such as WSN, RFID, NFC or Bluetooth with monitoring technologies such as dataloggers, TTI or other approaches are evaluated and compared in terms of dimensions, sensor parameter (temperature, relative humidity, water vapor, ethylene and other gases released during the biological processes), robustness, reliability, energy autonomy, bandwidth (if applicable), connection, among others. This study evaluates how these technologies can be successfully applied for traceability of horticultural products purpose and are what the future trends in terms of technical and technological specifications that will guide the development of these systems. It is expected that the increasing use of these systems for food traceability increase food quality and safety, reducing food waste.
