PDF417 2D Barcode
PDF417 is a barcode symbolo gy with the foll owing basic characteristic s:
nEncodable Character Set:
lText compaction mode permits all printab le ASCII characters to be enco ded, i.e.
values 32-126 incl usive in accordance w ith ISO/IEC 646 (IRV), as well as selected
control characters.
lByte compaction mod e permits all 256 possibl e 8-bit byte values t o be encoded.
This includes all ASCII characters value 0 to 127 inclusiv e and provides for
international ch aracter set support.
lNumeric Compaction mod e permits efficient encodi ng of numeric data strings.
lVarious function c odewords for control p urposes.
nSymbol character structure:
Each PDF417 symbol co nsist of a stack of v ertically aligned rows with a min imum of 3
rows (maximum 90 rows). Each row shall include a minimum of a 1 symbol ch aracter
(maximum 30 symbol characters), exclud ing start, stop and row indicator co lumns. The
symbol shall include a quiet zo ne on all four sides. Each character is 17 modules wide:
4 bar and 4 space elements with the largest element 6 modul e wide. SE450 specifies
each module is 2 do ts line wide.
nMaximum possible nu mber of data characters per symbol (at error correction level 0):
925 data codew ords which can encode :
lText Compaction mode: 1850 characters (at 2 dat a characters per codeword).
lByte Compaction mod e: 1108 characters (at 1.2 data characters per codeword).
lNumeric Compaction mode: 2528 characters (at 2.93 dat a characters per codeword).
At the minimum recommended error correction level, there is a maximum of 863 d ata
codewords which can encode:
lText Compaction mode: 1726 characters (at 2 dat a characters per codeword).
lByte Compaction mod e: 1033 characters (at 1.2 data characters per codeword).
