Wiliot is a well funded global leader in helping to track, assess and report conditions across the supply chain. Their cloud-based solution allows producers and retailers to track the storage condition of produce from farm to the store. Shippers or individual units can be tagged with a sticker-sized, battery-free, bluetooth connected tag which generate power by harvesting ambient RF energy. The tags can be equipped with a variety of sensors and also offers some processing power. In addition to managing the freshness of produce, Wiliot tags have use cases in areas of manufacturing, distribution, retail, ownership, and recycling. We believe Wiliot is an interesting solution for retailers looking to bring traceability and quality control measures to their entire supply chain.
