Chinese Sensible code is a matrix symbology

with selectable error correction levels. The

variable amount of nxn square symbols. A

crossing alignment pattern is available in

• sequentially: version 2 = 25 * 25, version 3 =

27 * 27, etc.

• maximum: version 84 = 189 * 189 modules

Error correction:

Four levels of Reed-Solomon error correction.

Additional feature:

Extended Channel Interpretion (ECI): support

for chinese character set, other different

character sets and data interpretions.

Support for this option is reader dependent.

The supported character set and the maximum

decodable number of characteristics is reader

dependent.

Encodable characters:

• numerical values 0-9

• ASCII value 0 - 127 ( ISO 646 )

• binary byte

• ordinary chinese characters ( GB 18030 - 2

Region, Double-byte, Four-byte )

• with ECI: many other character sets
