1
Can be any combination of 1∗erasures + 2∗substitutions (e.g. 13 maximum number of errors corrected might include 7
erasures and 3 substitutions).
2
Includes 1 module width quiet zone on either side.
3
Assumes the module height is 2∗module width, and includes one module width quiet zones on top and bottom.
4
Assumes Binary Compaction.
5
Assumes Text Compaction.
Table G-3: MicroPDF417 Characteristics Index
Note: Increasing the row/column/error correction values does not necessarily result in the ability
to encode more data.
Byte Compaction Mode: A value of 1 forces Byte Compaction, the best compression for binary
data. The compaction ratio is six 8-bit bytes of data compressed into 5 symbol codewords. See the
table above for the maximum data allowed for any row/column/error correction selection index.
Macro Character Substitution Disable: By default, Macro Character Substitution is enabled (0).
When enabled, Byte Compaction has priority over Macro Character Substitution. When Macro
