Data Matrix Data Matrix is a 2D matrix symbology which is made up of square
modules arranged within a perimeter finder pattern. The finder pattern is a perimeter to
the data region and is one module wide. Two adjacent sides are solid dark lines. These
lines are used to define physical size, orientation, and symbol distortion.
Maxicode Maxicode is a fixed-size symbology that is made up of offset rows of
hexagonal elements arranged around a bullseye finder pattern. Each hexagon represents
one bit of information and is either black or white depending on the state of the
encoded data bit. United Parcel Service (UPS) Research and Development developed
Maxicode for the specific purpose of encoding information about a parcel.
This symbology only encodes very specific data that is divided into the following
fields: a 5-digit zip code, a 4-digit zip code extension, a 3-digit country code, a 3-digit
class of service, and a string of uppercase letters, numbers, or limited punctuation
marks.
QR Code QR (Quick Response) Code is a matrix 2D symbology that encodes data into
patterns consisting of black and white dots or modules. A three position detection
pattern enables omni-directional reading and ultra high-speed reading. QR Code can
handle a wide range of data, including numerical, alphabetical, Kanji, Hiragana,
Katakana, graphics, and control codes. A built-in error correction function enables the
QR Code to repair errors in the code.
