QR Code

The QR Code symbology is a 2D matrix-style barcode symbology that can encode full 256 character extended-ASCII.

Also known as: Quick Response Code.

Variants:

• Micro QR Code is a small QR Code that is used in applications that require a small symbol space.
• GS1 QR Code is a variant of Data Matrix that should be used when encoding data that is in GS1 Application Identifier standard format.
• HIBC QR Code is a variant of QR Code that should be used when encoding HIBC formatted data.

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.
• 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 eclevel option is used to specify the error correction level:
  • eclevel=L - Low
  • eclevel=M - Medium (default)
  • eclevel=Q - Quality
  • eclevel=H - High
• The version option is used to specify the size of the symbol, 1 to 40.
• 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.
• The format option is used to select between format=full and format=micro symbol types. Alternatively, format=any will select the optimal symbol format for the given data. By default, full format symbols will be generated.
• Note: It is recommended that the Micro QR Code encoder is used for such symbols.
