We
all know that we live in a world of technology so all the all the thing
is bit quiter and smarter. QRCode is a very smart and tech way of our
modern world.
QRCode is like a shortner of data.
Have you heard of QR codes yet? Here is a quick introduction:
What Are QR codes?
They look like this:QR code (abbreviated from Quick Response Code)
is the trademark for a type of matrix barcode (or
two-dimensional barcode) first designed for the automotive industry in
Japan. A barcode is a machine-readable optical label that contains
information about the item to which it is attached. A QR code uses four
standardized encoding modes (numeric, alphanumeric, byte / binary,
andkanji) to efficiently store data; extensions may also be used.
The
QR Code system has become popular outside the automotive industry due
to its fast readability and greater storage capacity compared to
standard UPC barcodes. Applications include product tracking, item
identification, time tracking, document management, general marketing,
and much more.
A
QR code consists of black modules (square dots) arranged in a square
grid on a white background, which can be read by an imaging device (such
as a camera) and processed using Reed–Solomon error correction until
the image can be appropriately interpreted; data is then extracted from
patterns present in both horizontal and vertical components of the
image.
Mobile Phone Operating System
QR
codes can be used in
Google’s Android, BlackBerry OS, Nokia Symbian Belle
and Apple iOS devices (iPhone/iPod/iPad), as well as Microsoft’s Windows
Phone operating system, Google Goggles, 3rd party barcode scanners, and
the Nintendo 3DS. The browser supports URL redirection, which allows QR
codes to send metadatato existing applications on the device.
mbarcode is a QR code reader for the Maemo operating system. In Apple’s
iOS, a QR code reader is not natively included, but more than fifty paid
and free apps are available with both the ability to scan the codes and
hard-link to an external URL. Google Goggles is an example of one of
many applications that can scan and hard-link URLs for iOS and
Android. BlackBerry 10 devices have a native QR reader as well as
several third party readers. Windows Phone 7.5 is able to scan QR codes
through the Bing search app.
How does the cell phone read the code?
The cell phone needs a QR code reader, like this one from QRDroid It takes literally 1 minute for someone with an iPhone or Android phone to find and install the reader.
