The 2D (r)evolution in retail
The introduction of barcode scanning at cash registers in 1974 is now considered a technological revolution in retail, and the implementation of 2D codes represents at least as significant a milestone. Two-dimensional codes are already becoming a powerful communication tool. With the support of the GS1 standard, they not only provide consumers with greater information comfort, but also remain a key element in the efficient process of passing goods through the checkout system of retail stores.
