QR Code Bar Code
The ^BQ (QR Code) is a matrix symbology consisting of an array of
nominally square modules arranged in an overall square pattern. A
unique pattern at three of the symbols four corners assists in
determining the bar code size, position, and inclination.
A wide range of symbol sizes is possible along with four levels of
error correction. User-specified Module dimensions provide a wide
variety of symbol production techniques.
QR Code model 1 is the original specification while QR Code model 2
is an enhanced form of the symbology. Model 2 provides additional
features and can be automatically differentiated from model 1.
This bar code is printed using field data specified in a subsequent ^FD
stream.
Encodable character sets include numeric data, alphanumeric data,
8-bit byte data, and Kanji characters.
