To help in the tracking and tracing, nanotechnology provides complex invisible nanobarcodes with batch information which can be encrypted directly onto the food products and packaging. This nanobarcode technology offers food safety by allowing the brand owners to monitor their supply chains without having to share company information with distributors and wholesalers (Neethirajan and Jayas 2011). It is interesting that nanotechnology can provide not just security
but also the enforcement of brand-protection. Nanotechnologies can be embedded in a product to enable brand owners to assure customers of its authenticity and for investigators to identify genuine goods, making it very difficult for counterfeiters to imitate. Using nanotechnology, companies can encrypt unique product information such as data about growing conditions — climate and soil — collected from on-farm sensors. This can not only inform buyers about food quality, but also confirm product pricing and, very importantly, assure greater security and safety if a product recall requires data relating to product origins. Nanotechnology can also be encrypted with logistics information, such as processing or batch information, directly onto the
product or packaging (Roberts 2007). Oxonica in the United Kingdom offers solutions for food product identification and brand authenticity whereby the nanobarcodes become a biological fingerprint created by nanoparticles which generate unique reading strips for every food item
