QR stands for "Quick Response." It refers to a type of two-dimensional barcode that can store a large amount of data and can be scanned quickly and easily by digital devices such as smartphones
. The QR code was invented in 1994 by the Japanese company Denso Wave, a subsidiary of Toyota, to improve tracking of automobile parts during manufacturing. Unlike traditional barcodes, which store data only horizontally, QR codes store information both horizontally and vertically, allowing them to hold significantly more data and be read from any angle
. This quick scanning capability is the reason behind the name "Quick Response," as the code allows users to instantly access information encoded in it, such as URLs, contact details, or product information
