Quick
Response Code, worldwide known as QR Codes is a two-dimensional
barcodes, designed in Japan for the automotive industry, that encodes
information which can be any type of data.
Lately, it's
become popular owing to its fast readability and greater storage
capacity in comparison with standard barcodes.
It consists
of back modules in form of a square grid on a white back ground,
which can usually be read by a camera and processed using a special
application. Then, data is extracted from the components of the
image.
No matter
what the industrial design was for, these codes have grown common in
consumer advertising, being normally scanned by smartphones, which
convert it into something they can work with, such as an URL for a
website, making it unnecessary to type it into a browser. Almost
every type of smartphone has the software required to read QR codes.
The current
uses of these codes have expanded wonderfully, being now used in
different areas, from locating to marketing, or even printed on train
tickets in China.
