Java Barcode is a Java barcode generator which generates high quality 1D (linear) and 2D (matrix) barcodes in Java, Jasper Reports, iReport, and Eclipse BIRT projects.

 

Code 39 (also known as "USS Code 39", "Code 3/9", "Code 3 of 9", "USD-3", "Alpha39", "Type 39") is a barcode symbology that can encode uppercase letters (A through Z), digits (0 through 9) and a handful of special characters like the $ sign.

Code 39 is restricted to 44 characters. In Full ASCII Code 39 Symbols 0-9, A-Z, "." ,and "-" are the same as their representations in Code 39. Lower case letters, additional punctuation characters and control characters are represented by sequences of two characters of Code 39.

 

Java Code 39 Generator supports:

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  
  
• Uppercase letters (A - Z)
  
  
• - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus)

Java Code 39 Extension Generator supports:

• all 128 ASCII characters
