---

Reduced version of PDF417, smaller size, but with smaller capacity.
Micro PDF417 is designed for applications requiring improved area efficiency. Symbology can be used self or as secondary part of GS1 bar code symbol
Number of error correction codewords is fixed for each available row/column combination, from 7 to 50 codewords pre symbol.

Symbol size : Number of rows : 4 to 44 , Number of cols : 1,2,3 or 4

Data encoding mode	Maximum capacity
Text compaction	250 characters
Numeric compaction	366 characters
Byte compaction	150 characters

Additional features:

• Data compaction - Data is not directly represented on a one character for one codeword
• Extended Channel Interpretations - allow up to 811 800 different data character sets or interpretations to be encoded
• Structured append - use MacroPDf417 mechanism
• Edge to edge decodable
• Cross-row scanning
• Code 128 emulation codewords

MicroPDF417 characteristics CW : Codeword, EC : Error correction codewords, RW : Number of non error codewords-really used codewords without error correction codewords
