PDF417 is a 2D variable length symbology that can encode virtually any letter, number, or
character. 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 code word values and decoded data. PDF417 can accommodate up
to 340 characters per square inch with a maximum data capacity of 1850 text characters.
