End of the lines? QR-style codes could replace barcodes ‘within two years’

Retailers already trialling next-generation codes that can show sell-by dates, product instructions and ingredients. It is the zebra-striped tag that has become ubiquitous over the last 50 years, but the barcode’s days could be numbered. The global organisation overseeing their use has said a more powerful alternative will be readable by retailers everywhere within two years.
New codes that contain sell-by dates, product instructions, allergens and ingredients, as well as prices, will mean “we will say goodbye to the old-fashioned barcode”, according to GS1, an international non-profit that maintains the global standard for barcodes.
Tesco has started using them on some products, and other trials have suggested that waste of perishable food such as poultry can be cut by embedding sell-by dates in the new QR-style codes, allowing for more dynamic discounting. QR (quick response) codes will allow customers to instantly access more information about the product, including how to recycle batteries, clothes and building materials when tougher environmental regulations bite.
But they will also put a greater demand on the world’s cloud computing resources, where the extra data they contain will be stored – meaning a potentially greater carbon footprint. The first barcode was read in an Ohio supermarket in June 1974 when a packet of Juicy Fruit chewing gum was rung up. It was devised by Joe Woodland, an inventor who had been implored by a retailer frustrated at losing profits, to speed up checkout queues and stocktaking.
