History of QR Codes
A QR Code is a matrix code or two-dimensional bar code created by Japanese corporation Denso-Wave in 1994. The “QR” is derived from “Quick Response”, as the creator intended the code to allow its contents to be decoded at high speed.
Although QR Codes were initially used for tracking parts in vehicle manufacturing, QR Codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (also known as mobile tagging).
More recently, the inclusion of QR Code reading software on camera phones has led to a wide variety of new, consumer-oriented applications, aimed at relieving the user of the tedious task of entering data into their mobile phone.
QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards or just about any object that users might need information about.
