QR Code

A QR Code is a matrix barcode  (or two-dimensional code), readable  by QR scanners, mobiles phones with camera, and smartphones. The code consists of black modules arranged in a square pattern on white background. The information encoded can be text, URL or other data.

Common in Japan, where it was created by Japanese corporation Denso-Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. QR is the initialism of Quick Response, as the creator intended the code to allow its contents to be decoded at high speed.

QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards, or on just about any object that users might need information about. Users with a camera phone equipped with the correct reader application can scan the image of the QR Code to display text, contact information, connect to a wireless network, or open a web page in the phone’s browser. This act of linking from physical world objects is known as a hardlink or physical world hyperlinks.

Users can also generate and print their own QR Code for others to scan and use by visiting one of several free QR Code generating sites.
