Code One
c13[,[,m1][,m2,m3]]
There are 15 versions of Code One. Each version has a different maximum
data length.
Code One is a 2D matrix symbology that stores a checkerboard pattern of
data directly in a matrix. This feature makes Code One especially useful
for applications such as small parts labels, which do not provide sufficient
space for linear bar codes. Code One automatically generates error
correction symbol characters that it adds to the matrix. In addition to data
storage and error correction symbols, each Code One symbol contains a set
of horizontal lines in the center, called a finder pattern, that helps the
readers quickly locate and identify each symbol. Code One symbols also
contain vertical reference bars to help the readers locate the relative
positions of each data bit.
Code One symbols accommodate varying amounts of data using a
different method than other codes. Other codes adjust their size to fit the
data exactly. Code One symbols are divided into versions of specific sizes.
Each version can accommodate an amount of data from one bit to the
maximum amount that will fit into that version. If more data is present
than the version can accommodate, the printer will not print the label.
Code One symbols cannot be read with a laser scanner. They are read by a
digital imager that captures the entire symbol at once instead of scanning
each component individually. The imager decodes the components of each
Code One symbol after it captures the image, permitting faster data
collection.
