A "farm-to-fork" traceability technology is gaining adoption worldwide. This technology increases transparency between buyers and sellers and is helping to improve supply chain integrity, map farms, prevent product fraud, improve productivity, and reduce postharvest loss. HarvestMark, provided by California-based IT company YottaMark, helps buyers trace the origin and cultivation of 4.5 billion food products to date by scanning QR codes with mobile phones. In developing countries, the same technology can be used, via mobile phone, to deliver information to farmers about optimizing cultivation, preventing the purchase of counterfeit inputs, demonstrating compliance with strict industry standards, tracking production volume, measuring quality, and identifying sources of waste. HarvestMark works with more than 400 companies in the US, China, Peru, Chile, Argentina, and Mexico, as well as other countries.

A UK-based company called GeoTraceability has developed a similar device to track the cocoa supply chain in Ghana for trading company, Armajaro. GeoTraceability is using mobile phones, barcoding, and web database technology, to: (1) implement a stock management system at each buying level, (2) map cocoa fields, (3) record production history through GPS, and (4) provide capacity building information to farmers.
