QRCode
QR Code is a 2D barcode readable by QR scanners, mobile phones and smart phones
with a camera. The code consists of black modules arranged in a square pattern on
white background. The information encoded can be most any text data.
Although initially used for tracking parts in vehicle manufacturing, QR Codes are now
used in a much broader context, including both commercial tracking applications and
convenience-oriented applications aimed at mobile phone users (known as mobile
tagging). Denso Wave, Inc. invented the QR Code Barcode. T
he word “ QR Code” is a
registered trademark of DENSO WAVE INCORPORATED. This registered trademark
applies only for the word “QR Code”, and not for the QR Code pattern or image.
QR Codes storing addresses and URLs may appear in magazines, on signs, buses,
business cards, retail receipts, or on just about 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 phone's browser. This act of linking from
physical world objects is known as a hard link or physical world hyperlinks.

–Solomon error correction and the error correction capacity may
be adjusted.
Error correction
Level L
7% of code words can be restored.
Level M
15% of code words can be restored.
Level Q
25% of code words can be restored.

If numeric data is used, the barcode generator will optimize the barcode generation for
numeric data. In Alpha numeric mode the printer will encode 0-9, A-Z, space, %, *, +, -,
.,/ and :.
