Book excerpt: Business transactions in agriculture have been transformed by the digitisation of the value chain. The first big impact came with barcodes, which made it possible to track items through a value chain. Then came handheld mobile data collection devices, more affordable sensors to track conditions, followed by the internet to transform links with consumers. Mobile phones now take over many of these roles. Barcodes have been replaced with RFID and QR codes. Despite this progress, there are still many challenges relating to the traceability of products and transparency in supply chain management. Database systems managing transaction records were managed in isolation, not open to all the other stakeholders in the chain; they were open to fraud, and transactions were difficult to secure.
