A QR code, short for "Quick Response," was developed by Japanese engineer Masahiro Hara in 1994. These two-dimensional barcodes utilize matrix scanning technology to graphically encode information and provide rapid access to it.

QR codes represent a pattern of black and white squares, forming a square design. This pattern can store various types of information such as text, links, contact details, geographic locations, and more.

QR codes allow for easy access to this information using a smartphone or tablet.
