What is qrg?

QRG (Quick Response Guide) is a type of barcode that can be scanned with a smartphone camera. It was originally created in Japan in the 1990s and quickly gained popularity due to its ability to store more information than traditional barcodes. QRGs are now widely used for a variety of purposes, including marketing, tracking inventory, and providing easy access to information. They can be found on product packaging, advertisements, business cards, and even billboards. QRG technology has evolved over the years to include features such as dynamic QR codes that can be updated with new information even after they have been printed, and the ability to link to mobile apps and websites.
