QR Code —
abbreviated from Quick Response Code — is the trademark for a type of
matrix barcode (or two-dimensional code) first designed for the
automotive industry. More recently, the system has become popular
outside of the industry due to its fast readability and large storage
capacity compared to standard UPC barcodes. The code consists of black
modules arranged in a square pattern on a white background. The
information encoded can be made up of four standardized kinds ("modes")
of data (numeric, alphanumeric, byte/binary, Kanji), or by supported
extensions virtually any kind of data.

Although
initially used to track parts in vehicle manufacturing, QR Codes are
now (as of 2012) used over a much wider range of applications, including
commercial tracking, entertainment and transport ticketing,
product/loyalty marketing (examples: mobile couponing where a company's
discounted and percent discount can be captured using a QR Code decoder
which is a mobile app, or storing a company's information such as
address and related information alongside its alpha-numeric text data as
can be seen in Yellow Pages directory), band in-store product
labelling. It can also be used in storing personal information for use
by government. An example of this is Philippines National Bureau of
Investigation (NBI) where NBI clearances now come with a QR Code. Many
of these applications target mobile-phone users (via mobile tagging).
Users may receive text, add a vCard contact to their device, open a
Uniform Resource Identifier (URI), or compose an e-mail or text message
after scanning QR Codes. They can generate and print their own QR Codes
for others to scan and use by visiting one of several pay or free QR
Code-generating sites or apps. Google has a popular API to generate QR
Codes and apps for scanning QR Codes can be found on nearly all
smartphone devices.
QR
Codes storing addresses and Uniform Resource Locators (URLs) may appear
in magazines, on signs, on buses, on business cards, or on almost any
object about which users might need information. 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 telephone's browser. This act of
linking from physical world objects is termed hardlinking or object
hyperlinking. QR Codes may also be linked to a location to track where a
code has been scanned. Either the application that scans the QR Code
retrieves the geo information by using GPS and cell tower triangulation
(aGPS) or the URL encoded in the QR Code itself is associated with a
location.
QR
Codes can be used in Google's mobile Android operating system via both
their own Google Goggles application or 3rd party barcode scanners like
ZXing. The browser supports URI redirection, which allows QR Codes to
send metadata to existing applications on the device. Nokia's Symbian
operating system features a barcode scanner which can read QR Codes while
mbarcode is a QR Code reader for the Maemo operating system. In the
Apple iOS, a QR Code reader is not natively included, but more than
fifty paid and free apps are available with both scanning capabilities
and hard-linking to URI. With BlackBerry devices, the App World
application can natively scan QR Codes and load any recognized Web URLs
on the device's Web browser. Windows Phone 7.5 is able to scan QR Codes
through the Bing search app.
In
the USA, QR Code usage is expanding. citation needed During the month
of June 2011, according to one study, 14 million mobile users scanned a
QR Code or a barcode. Some 58% of those users scanned a QR or bar code
from their home, while 39% scanned from retail stores; 53% of the 14
million users were men between the ages of 18 and 34. QR Codes are also
being tested for "virtual store" formats, particularly in South Korea
and Argentina.
While
the adoption of QR Codes in some markets has been slow to begin
(particularly in markets such as the United States, where competing
standards such as Data Matrix exist), the technology is gaining some
traction in the smartphone market. Many Android, Nokia, Blackberry
handsets, and the Nintendo 3DS, come with QR Code readers installed. QR
reader software is available for most mobile platforms. Moreover, there
are a number of online QR Code generators which enable users to create
QR Codes for their own needs.
