Code 39 Extended (Full ASCII Code):

Standard Code 39 contains only 43 characters (0-9, A-Z, $, /, %,

+). Code 39 can be extended to an 128 character symbology (full ASCII) by combining one of the

special characters ($, /, %, +) with a letter (A-Z) to form the characters that are not present in the

standard Code 39 symbology. For example, in standard Code 39 a lowercase "a" cannot be

represented. In Code 39 Full ASCII, however, "a" is represented as "+A".

Code 39 Example (No Check Digit)

Code 93

Code 93 encodes the full 128 ASCII character set using 9 modules arranged into 3 bars with adjacent

spaces. Two of the characters are check characters. Code 93 is similar to Code 39 but encodes more

characters per inch. Code 93 encodes the full 128 ASCII character set and is encoded similarly to Code

39 Extended.

Data Matrix

Data Matrix is a 2D, variable length symbology capable of encoding all 128 ASCII characters and a

number of different character sets. Each Data Matrix symbol consists of a perimeter quiet zone, border

with two solid edges and two dashed edges, and cells inside the border which are dark or light. The

border's two solid lines with data cells are used for symbol identification, orientation, and cell location.

Data Matrix can accommodate up to 500 MB per square inch with a data capacity of 1 to 2335

characters. Data Matrix has a high degree of redundancy and resists printing defects.

Data Matrix is popular for labeling small products because it can encode many characters in a small

area. It is becoming the industry standard for marking small electronic equipment. It is also used in the

aeronautical industry and the US Department of Defense. Data Matrix barcodes can be read by smart

phones by downloading a reader.
