Internationally, the codes are being used in Japan, Australia, and New Zealand to show foods' freshness and shelf life. They will link to information about the sneakers' materials and the company's sustainability efforts. Puma was the first company to announce it is using 2D barcodes in US stores and products. Since they were first used to label car parts in Japanese factories in 1994, the popularity of QR codes has continued to increase, and their use exploded during the pandemic. The 2D codes can also give access to loyalty points, games, and coupons. They can reveal promotional offers, the factory where something was created, a company's sustainability practices, and even information on recycling the product or packaging. It's not just information on foodstuff that 2D barcodes are useful for. Scanning one on a food item's packaging using a phone, for example, will offer up information such as its ingredients, recipes it can be used in, potential allergens, and where it was grown. The 2D codes also have plenty of benefits for consumers. Retailers can also expect the codes to greatly improve their inventory control. They'll also be able to see when food is nearing its expiry date and offer discounts. Axios writes that stores will be able to immediately respond to product recalls and identify faulty items. Unlike the standard 12-digit barcode, the 2D versions, which look like squares or rectangles containing many small, individual dots (QR codes are one version), can reveal lots about a product. It's used universally on consumers products, but its functionality is limited compared to the 2D versions, which can hold a lot more information that is encoded on both the horizontal and vertical axes. The familiar barcode square filled with thin and thick vertical lines has been around for decades. But it's set to be phased out by 2027 in favor of a more capable successor: 2D barcodes. In brief: The barcode has been a familiar sight for almost 50 years, found on packaging for virtually every consumer item in the world.
