Traceability is the ability to retrieve the history, use, location or activity of an identified item, hence crop traceability system is a system that provides unique identification to the crop and tracks all information from the seed until the end product in the market. Crop traceability is beneficial to agri-business owners, farmers and consumers as it enables the production of quality crops. This paper aims to study the emerging crop traceability technologies in smart farming and present the possible solutions to improve the crop traceability system based on the ICT perspective. Some of the technologies involved are barcode, QR code, RFID, IoT, artificial intelligence and blockchain. Among these technologies, blockchain is seen to be the future technology suitable to improve the crop traceability system. However, the integration of blockchain into the existing system is still in the infancy stage.
