Which Bar Code Do You Need?

Bar Code 93    Bar Code 93 example
Bar Code 93 was introduced in 1982 and was designed to complement bar code 3 of 9. Bar code 93 is a high density alpha-numeric bar code that also supports a Full ASCII version without the ambiguity of the 3 of 9 bar code. The standard version can encode 47 characters: A-Z, 0-9, plus "-", ".", " ", "$", "/", "+", "%", and 4 special characters for Full ASCII mode. Each bar code can be of variable length and requires two checksums.
  • Encodes: Only 47 characters: 0-9, A-Z, and space $%+-./ plus 4 special characters for Full ASCII encoding
  • Length: Variable
  • Checksum: Required

While the requirement for two separate checksum calculations for each bar code requires more resources, the ability to intermix Full ASCII characters in bar code 93 is a distinct advantage over bar code 39.
