7 Benefits of QR Code for
Consumers
- Bar code yesterday
Various types of bar codes
have become label standards
for many industries for their
reading speed and accuracy.
Bar codes spread wide a
market need arose to expand
the volume of data stored
within and to decrease the
printed size of the code. Do
you remember products with
multiple bar codes, because
producers though that one is
not enough? Or those official forms with stacked bar codes on the
side? All these were desperate measures to pack as much
information into as little of paper space. This was the moment
when in 1994 Denso, a Japanese company, came up with a two
dimensional, matrix type kind of code.

Being a 2D code, the QR code (abbreviation form Quick Response
code) holds data in both the horizontal and vertical axes, and it is a
big breakthrough since conventional bar code contains information
only in one. Just imagine how much more data it is possible to
store in QR code than in bar code.
- Benefits of 2D Codes
1. High data capacity. A standard QR code can contain up to
7,089 numeric characters or 2,953 bytes of binary
information.
2. Data variety. Besides numeric and alphabetic characters, QR
code can encode Kanji, Kana, Hiragana, symbols, binary, and
control codes. As far as Japanese characters are concerned,
one Kana or Kanji character is encoded in 13 bits, which is at
least 20% less compared to other 2D codes.
3. Small printout size. The use of horizontal and vertical axes
to store information enables to store approximately ten times
more information on the same printout area. That is to say
nothing about Micro QR Code, which is even smaller.
4. Dirt and Damage Resistance. QR code has an in-build data
error correction feature. The data contained within can be
restored even when it is partially dirty or damaged.

5. 360° readability. QR codes can be scanned from any
direction. You don’t have to align them to get them scanned.
6. Structured Append Feature. A QR code can be divided into
a maximum of 16 smaller QR code symbols for a more
convenient printing.
7. Open specifications. Compared to other 2d codes, QR code
specifications are defined in detail, disclosed to everyone and
patent right re not exercised by Denso Wave, the patent right
owner.
Note, that every QR code requires margins on all sides around the
code square for proper reading
