QR Code for the URL of the English Wikipedia Mobile main page. Note that the white border is part of the encoding.

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.[1]

Overview

Although 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 (known as mobile tagging).

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. Google's mobile Android operating system supports the use of QR codes by natively including the barcode scanner (ZXing) on some models and the browser supports URI redirection, which allows QR Codes to send metadata to existing applications on the device. Nokia's Symbian operating system is also provided with a barcode scanner, which is able to read QR Codes [citation needed], while mbarcode [2] is a QR code reader for the Maemo operating system.

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.

Standards

A giant QR Code linking to a website, to be read with a mobile phone.

There are several standards documents covering the physical encoding of QR Code:[3]

At the application layer, there is some variation between implementations. NTT DoCoMo has established de facto standards for the encoding of URLs, contact information, and several other data types.[5] The open-source "ZXing" project maintains a list of QR Code data types.[6]

License

The use of the QR Code is free of any license. The QR Code is clearly defined and published as ISO standard. Denso Wave owns the patent rights on QR Code, but has chosen not to exercise them.[3]

The term QR Code itself is a registered trademark of Denso Wave Incorporated.[7]

Storage

QR Code data capacity[1]
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary (8 bits) Max. 2,953 bytes
Kanji/Kana Max. 1,817 characters
Error correction capacity
Level L 7% of codewords can be restored.
Level M 15% of codewords can be restored.
Level Q 25% of codewords can be restored.
Level H 30% of codewords can be restored.

QR codes use the Reed–Solomon error correction.

Variants

Example of Micro QR

Micro QR Code is a smaller version of the QR Code standard for applications with less ability to handle large scans. There are different forms of Micro QR Code as well. The highest of these can hold 35 characters.

Design QR is a QR Code that was optimized to include a picture or logo to enhance conversion rates. [8]

Use as artwork

Since 2006 the Italian artist Fabrice de Nola uses QR codes in oil paintings or embedded in photographs.[9]

In 2007 the British pop group Pet Shop Boys used QR code for the artwork of their download-only single Integral. The videoclip for the song also features QR code. When the codes are scanned, users are directed to the Pet Shop Boys website, and web pages about the British national identity card plans, respectively.

In 2009 the Japanese artist Takashi Murakami, in collaboration with creative agency SET and Louis Vuitton, created a design QR featuring the LV pattern and one of the artist’s characters.[10]

In 2010 the musician and artist DJ Spooky used QR code in a fine art print exhibited at Experimenta Biennale, Melbourne. Scanning the code takes users to an experiential web based artwork called the Nauru Ellegies,[11] about the complexities of the South Pacific island of Nauru.

A QR code which scans to produce the word "LOVE" was also featured prominently in Australian artist Kylie Minogue's music video for her 2010 single All The Lovers.

In June 2010, the Design Exchange, Canada's National Design Centre, unveiled a large QR installed created by Rollout Wallpaper. Rollout Wallpaper is a custom wallpaper company operating in Vancouver. The installation is part of the 'Bent Out of Shape' exhibit, curated by Design Exchange staff.

Standalone Applications

While the adoption of QR codes in some markets, including the United States, has been slow to take off, the technology is gaining some traction in the smartphone market. Many Android phones come with QR code readers already installed. Blackberry phones running Blackberry Messenger 5.0 (or more recent versions) can also scan QR codes using the "Scan A Group Barcode" option in the BBM menu. Both the Android Market and the iTunes App Store offer several free applications that can decode QR matrices.

Generating QR codes is slowly moving into the mainstream in America as well. There are numerous internet platforms which allow users to create and manage QR codes. Many generating platforms will also allow users to view analytics on how and when the code is being scanned.
