New Chinese 2D Bar Code has been announced by AIM Inc.

Press Release Summary:

Han Xin Code 2D matrix symbology, made up of square modules arranged in overall square pattern, features finder patterns that assist in location of position, size, and inclination. In addition to capability to encode double-byte Chinese characters (GB18030), symbology can efficiently encode numeric and ASCII characters as well as octet bytes such as graphic/audio information. Also, user-selectable levels of Reed-Solomon error correction ensure correct decoding even with damaged symbols.

AIM Inc. Announces Availability of New Chinese 2D Bar Code

Han Xin Code Encodes Chinese, Numeric and ASCII Characters Plus Octet Byte Data

Cranberry Township, PA - AIM Inc., the trade association recognized as the worldwide authority on automatic identification and mobility, today announced the availability of Han Xin Code symbology.

Han Xin Code is a two-dimensional matrix symbology made up of an array of square modules arranged in an overall square pattern. Unique finder patterns assist in easy location of its position, size and inclination.

In addition to the symbology's capability to efficiently encode double-byte Chinese characters (GB18030), Han Xin Code can efficiently encode numeric and ASCII characters (reference to ISO/IEC 8859-1) plus octet bytes such as graphic and audio information. The symbology includes user-selectable levels of Reed-Solomon error correction to ensure correct decoding even with damaged symbols.

There are eighty-four sizes (versions) of Han Xin Code symbols. Version 1 measures 23 modules × 23 modules; Version 84 measures 189 modules × 189 modules. Module dimension is user-specified to enable production of symbols by a wide variety of techniques.

Maximum symbol data capacities are 7827 numeric characters, 4350 ASCII characters, 2174 Common Chinese Characters in Region one or Region 2, 1739 2-byte Chinese characters data, 1044 4-byte Chinese characters, and 3261 binary byte data. Multiple data types can be encoded in the same symbol.

As with all AIM symbology specifications, Han Xin Code has undergone a rigorous review process in AIM's Technical Symbology Committee (TSC) to ensure that a new symbology offers unique or novel features that provide additional benefits to the user community and that it is robust from both a printing and reading perspective.

According to Chuck Evanhoe, AIM board chairman, "AIM is pleased with the close cooperation of AIM China and the Han Xin Code development team in developing this International Technical Specification. This symbology has already been deployed in a variety of applications within China and this standard will help vendors and end users adopt it for additional applications with confidence. We encourage the submission of this symbology for consideration as an international standard under ISO/IEC."

"China is a vital and vibrant market for bar code technology and the development of this symbology specification is a key for future global growth in the region. AIM appreciates the hard work and dedication of the Han Xin Code team, those who offered comments and recommendations during public review, and, of course, the members of the TSC who dedicated their time and expertise to ensuring the robustness of the specification."

AIM documents are available for purchase from the AIM online store at The Han Xin Code document can be accessed directly online. A package with demonstration Han Xin Code encoding and decoding software programs is also available in the AIM online store. Images are available upon request.
