A multi row symbology, Code
49 offers high information density encoding of the full
(128-character) ASCII set. Character encodation, reference
decode algorithm and optional check character calculation
are included in this document. |

| A multi row symbology, Code 16K offers high
information density encoding of the full (128-character)
ASCII set and double density encoding of numeric data
strings. A new feature also allows the encodation of extended
ASCII for non-English language characters. Character encodation
(code sets A, B, and C), reference decode algorithm and
optional check character calculation are included in this
document. |

| Codablock F is a multi-row symbology.
The structure of the multi-row matrix is governed by rules
which conform to this specification. The data and
symbol characters are identical to those of Code 128.
Each row is structured so that it conforms fully to the
rules of the basic encodation symbology. Character
near the beginning and end of each row, not part of the
encoded data in the row, are relevant to the structure
of the Codablock symbol. |

| PDF417 is a two-dimensional, multi-row
symbology designed to be scanned by laser scanners and
linear CCD scanners. The symbology can be decoded even
when scan lines cross rows. PDF417 is designed with selectable
levels of error correction. It supports industry standard
escape sequences to define international code pages and
special encodation schemes. PDF417 is used to encode data
files with hundreds or thousands of characters in a laser
scannable symbol. This document includes descriptions
of the character encodation, symbol structure, reference
decode algorithm, and symbol quality measurements for
PDF417. |

| MicroPDF417 is a multi-row symbology, derived
from and closely based on PDF417. MicroPDF417 is designed
for applications with a need for improved area efficiency
but without the requirement for PDF417's maximum data
capacity. A limited set of symbol sizes is available,
together with a fixed level of error correction for each
symbol size. Module dimensions are user-specified to enable
symbol production and reading by a wide variety of techniques. |
