What is QR code ?

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.

QR Codes (also known as Quick Response Codes) are becoming more and more popular. These two-dimensional codes composed of square dots are now used in various areas of life. You can find them on ads, banners, all kinds of product boxes, websites, business cards and even in email signatures.

QR Codes may contain text, links (to websites, videos or files), email addresses, phone numbers, vcards that automatically update your contacts on your PC or a mobile phone, and more.

QR codes can be used on mobile systems using specialized software. Android supports URL redirection, which allows you to send QR codes metadata to applications on the device. The Nokia Symbian operating system is equipped with a barcode scanner that can read QR codes. The mbarcode application is the QR code reader for the Maemo system. In Apple iOS from version 11, the QR code reader is built into the system Camera application. In older systems, the reader is not present by default, but there are many applications available in the App Store that can both read QR codes and create them. On BlackBerry devices, the App World application can read QR codes, recognize a web address in them and load it in the system browser. Windows Phone 7.5 can read QR codes and open the web address they contain using Bing Vision. QR codes can also be used on Nintendo 3DS.
