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.
