PDF417
PDF417 is a stacked linear barcode symbol format used in a variety of applications, primarily transport,
identification cards, and inventory management. PDF stands for Portable Data File. Each character
consists of 4 bars and 4 spaces in a 17 module structure. The name of the symbol is derived from the
format of the code. PDF stands for "Portable Data File" and "417" is derived from the module structure.
Each PDF417 symbol consists of 3 to 90 stacked rows surrounded by a quiet zone on all four sides.
Each row consists of a leading quiet zone, start pattern, left row indicator character, one to thirty data
characters, right row indicator character, stop pattern, and trailing quiet zone.
PDF417 supports text compaction, numeric compaction, and byte compaction that correlate the
mapping between codeword values and decoded data. PDF417 can accommodate up to 340
characters per square inch with a maximum data capacity of 1850 text characters.

POSTNET
POSTNET (Postal Numeric Encoding Technique) is a barcode symbology that is used by the United
States Postal Service to assist in directing mail. The ZIP Code or ZIP+4 code is encoded in half- and
full-height bars. Most often, the delivery point is added, usually being the last two digits of the address
or PO box number.
The barcode starts and ends with a full bar (often called a guard rail or frame bar and represented as
the letter "S" in one version of the USPS TrueType Font) and has a check digit after the ZIP, ZIP+4, or
delivery point. The encoding table is shown on the right.
Each individual digit is represented by a set of five bars, two of which are full bars (i.e. two-out-of-five
code). The full bars represent "on" bits in a pseudo-binary code in which the places represent, from left
to right: 7, 4, 2, 1, 0. (Though in this scheme, zero is encoded as 11 decimal, or "binary" 11000.)
