1Can be any combination of 1∗ erasures + 2∗ substitutions (e.g. 13 maximum number of errors corrected might include 7 erasures and 3 substitutions).

2Includes 1 module width quiet zone on either side.

3Assumes the module height is 2∗ module width, and includes one module width quiet zones on top and bottom.

4Assumes Binary Compaction.

5Assumes 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
