correction modes, seven different storage modes, the capability to use character sets other than ASCII,
and the capability to “link” several MaxiCodes together. Since there are so many different modes, it is
suggested that you contact AIM for the symbol specification. If you are developing software to be used
with the UPS MaxiCode shipping system, contact UPS for information on how to order the information on
the Maxicode shipping system.
QR Code
QR Code is a 2-D symbology developed in 1994 by Denso Wave, a Japanese company (a division of
Denso Corporation at the time), with the primary intent of creating a symbology that is easily interpreted
by inexpensive scanner equipment. It has since become the most popular 2-D barcode used in Japan.
QR Code is capable of handling several dozen to several hundred times more information than
conventional bar codes. The QR Code specification is “open” in that the QR Code specification is
disclosed and the patent right owned by Denso Wave is not exercised. QR Code is established as an ISO
(ISO/IEC18004) standard.
QR Code is capable of handling a variety of data, such as numeric and alphabetic characters, Kanji, Kana,
Hiragana, symbols, binary, and control codes. Up to 7,089 characters can be encoded in one symbol.
Since QR Code carries information both horizontally and vertically, it is capable of encoding the same
amount of data in approximately one-tenth the space of a traditional bar code. Its error correction
capability allows restoration of data even if the symbol is partially damaged or dirty.
QR Code utilizes position detection patterns located at three corners of the symbol to accomplish
omni-directional (360º) reading. These position detection patterns guarantee stable high-speed reading,
circumventing the negative effects of background interference.
Two Dimensional Barcode Commands
The following commands are used for the creation and formatting of two-dimensional bar codes.
Insure that the bar code symbology chosen agrees with its intended use. We recommend acquiring
the specification for the desired code to supplement the discussions in this manual.
Note that Codablock “A” and “F” are not fully supported in this release of the manual.
