More recently, iOS and Android apps are appearing which allow consumers to get various information (nutritional information, ...) and track the origin of products they buy and sometimes also get additional information such as the distance the product has travelled from its production location to the consumer (i.e. OpenLabel, Glow, Open Food Facts, ...). These apps may rely on barcode scanning. Also, smartphones can simply scan the QR code, after which a link in the browser opens up showing the production location of the product (i.e. Farm to Fork project, ...).
