The value represented by the bar code |
This symbology is a very compact bar code for all alphanumeric applications.
The full (128-character) ASCII character set can be encoded in this symbology without the double characters found in extended Code 39.
If the bar code has four or more consecutive numbers (0–9), the numbers are encoded in double-density mode (where two characters are encoded into one character position).
Code 128 actually has three different character-code subsets. It has two forms of error checking, making it a very stable bar code.
Checksums are not required.
If you have a choice, Code 128 is generally the best all round one.
