Micro QR Code

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:

• QR Code is the more popular, larger variant.

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

Data and Options

• 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.
