Bar Code Symbols and Formats

Data Matrix

Data Matrix is a high-density, 2-D matrix bar code symbology developed by RVSI - Acuity

CiMatrix, which can encode a lot of information in a very small space. The Data Matrix

symbology has extensive error correction capabilities, which uses the ECC200 error

checking method. A Data Matrix symbol can store between 1 and 3,116 numeric or 2,335

alphanumeric characters, and is scalable between a 1 mm square to a 14" square.

Since the overall size of the Data Matrix symbol is infinitely scalable, the Data Matrix symbol

can be read at virtually any distance, given the right combination of size and reading

equipment.

The Bar Code Printing function can scale the Data Matrix bar code by defining the small

black square height and width. It also automatically optimizes the encoding (binary, text, and

digits) by analyzing the data.

NOTE

For more information on the Data Matrix symbol options, see "Font Parameters," on

p. 3-2.

Aztec Code

Aztec Code is a 2-D matrix bar code symbology developed by Welch Allyn. It is designed to

combine the best characteristics of several first generation symbols with special attention to

the ease of printing, orientation, field distortion, high-level data security with user selected

redundancy, and efficient storage for small to large data messages. The smallest Aztec Code

symbol encodes 13 numbers or 12 letters, while the largest Aztec Code symbol encodes

3,832 numbers, 3,067 letters, or 1,914 bytes of binary data. The Bar Code Printing function

can scale the Aztec Code by defining the small black square height and width.

NOTE

For more information on the Aztec Code symbol options, see "Font Parameters," on

p. 3-2.
