The Code 128a barcode specification is used in IDAutomation Barcode Fonts, Components and Applications to create a Code 128 Barcode in character set A, which includes upper case letters, numbers and several functions.
- Using the Code 128a Barcode Fonts option with a font encoder returns text formatted to Code 128 Barcode specifications.
- Using Uni_C128a with a Universal Barcode Font Encoder returns text formatted to the Universal Barcode Font, a single cross-platform font (Windows, MAC, Linux and Unix) that creates several barcode types.
- The Code128a barcode option in all Components and Applications will produce a barcode image that includes all applicable start and stop digits with checksum characters when required.
Caution should be used in Code 128 character set A because lowercase characters will create a function according to the Code 128 Barcode Character Set. This can be useful, however, when a tab or return needs to be easily encoded in the barcode symbol.
For example, the following data string in character set A encodes “CODE<tab>128<tab>BARCODE<return>”:
The Code 128a barcode type is easily read and verified with the IDAutomation USB Barcode Scanner.
