Codabar
Codabar has a character set of 16 characters. It is a discrete, self-checking symbology and is
most commonly used in libraries and blood banks.
NW-7
NW-7 is similar to Codabar. It uses numeric characters only and a different checksum
algorithm.
Code 128/USS 128
Code 128 is a continuous, variable length symbology. This symbology has 106 different
printed characters.
Code 128 is character dependent. See AIM Uniform Symbol Specification (USS) Rev. 1986 for
additional required dimensional tolerances.
You must use and print a checksum character, and it must conform to the AIM USS 128
checksum generation procedure. DO NOT use the following values, as they are not
recognized as valid values:

No bar-code symbology is perfect. You will occasionally get a read error. Following are some
tips to help you get the best performance from the symbology you choose:
r
Use high quality labels.
r
Always use a check character.
r
Use fixed length bar-code information.

Use Bearer Bars with Interleaved 2-of-5.
r
When using the handheld scanner, check that the label was decoded correctly.
