2. The letters Q and R stand for quick response. This code was so
named because the main purpose of the code development was
to create a code that could be read quickly. This is the origin of
its name. However the official name of the code is QR Code, and
this should never be interpreted as an acronym for "Quick
Response" Code.
QR code can hold nearly 3kb (8 bit) data. QR bar code can be as
large as 177 by 177, allowing for 31,329 dots. That is enough
space for about 3kB, even allowing for position, alignment,
timing, version, and formatting information.
Numeric only: Max. 7,089 characters
Alphanumeric: Max. 4,296 characters
Binary (8 bits): Max. 2,953 bytes
Kanji/Kana: Max. 1,817 characters
3. Uses of QR code.
No matter how small or large, your business could use QR codes in a number of ways.
You might auto generate one next to every product on your web site containing all the
product details, the number to call and the URL link to the page so they can show their
friends on their cell phone. You could add one to your business card containing your
contact details so it’s easy for someone to add you to their contacts on their cell phone.
Add them to any print advertising, flyers, posters, invites, TV ads etc. containing:
Product details
Contact details
Offer details
Event details
Competition details
A coupon
Twitter, Facebook, Myspace IDs
A link to your YouTube video
Location map
QR Code is used in a wide variety of applications, such as manufacturing, logistics,
and sales applications.

5. QR code can hold binary data only. So every block of image store binary information regards any
Details of the product.

8. QR Code can store binary data. Therefore, images and sounds can be stored in it as
binary data. However, the amount of data that can be stored in a QR Code is about 3 KB
or less (for Version 40 with correction level L) at the maximum.
Images or sounds that can be expressed with this amount of data are very limited. For
the case where a QR Code is read using the camera feature of the mobile phone, the
amount of data read in with it is 271 bytes or so (for Version 10 with error correction level
L), though this figure may vary depending on phone's manufacturer and its model type.
Therefore, it is prudent to assume that images and sounds cannot be stored directly in
QR Code for practical purposes when using the phone to read data.
The size of a QR Code can be determined from the size of its modules and the version
of the code. A module refers to a black or white square dot making up the code. Which
version to use depends on the amount of data to be encoded. Version 1 QR Code has
21 modules on its side.
For a one step larger version of the code, the number of modules on the side increases
by 4, and the largest version is 40. Version 2 QR Code, for instance, is made up of 25 x
25 modules. Provided the size of a module is 0.5 mm, the size of this version of the code
is 12.5 x 12.5 mm (a white space worth 4 modules is needed around it if you actually
want to put it to use).
9. A machine-readable code consisting of an array of black and
white squares, typically used for storing URLs or other information
for reading by the camera on a smartphone.
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.

Visit the website which means QR code storing the URLs of the website.

11. The main advantage of a QR code is its versatility. QR codes can be used for anything
and everything. They are also beneficial for both customers and businesses. For
example, a business saves money and advertising costs by distributing a QR code to
their website or URL. A customer can scan this QR code and this allows them to store
the information for future reference. What’s also greater about QR codes is that they
bridge different forms of marketing streams together. For example ecommerce and
mobile commerce are both used for QR codes. QR codes acts as the link and it also
exposes customers to other forms of advertising the business or service of the QR code
has done. This maximizes exposure and can potentially generate revenue.
The down side of QR code users must be equipped with a camera phone and
the correct reader software that can scan the image of the QR Code.
Currently only Smartphone’s are technically equipped to do this. Many users
that have mobile phones that have cameras are unable to get QR reading
software for their phones.
