Micro QR Code

The Micro QR Code symbology is a smaller variant of QR Code that is used in applications that require a small symbol space.

Also known as: Micro Quick Response Code.

Variants:

Standards: ISO/IEC 18004, JIS X 0510, ITS - QR Code, AIM ISS - QR Code.

The data field can contain any extended ASCII data. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1.
An appropriate size will be selected to work around the following restrictions:
- An M1 symbol is only compatible with numeric data.
- An M2 symbol is only compatible with alphanumeric data.
When the parse option is specified, any instances of ^NNN in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters.
The version option is used to specify the size of the symbol, either version=M1, version=M2, version=M3 or version=M4.
The eclevel option is used to specify the error correction level:
- eclevel=L - Low (default)
- eclevel=M - Medium; Not compatible with M1 symbols
- eclevel=Q - Quality; Only compatible with M4 symbols
The fixedeclevel option will prevent the error correction level from being opportunistically raised when a better fix to the current matrix is possible.
If unspecified the encoder will select the version of the symbol that is the minimum size to represent the given data at the selected error correction level.
