The Code 128
barcode was developed by COMPUTER IDENTICS in 1981. It is a
variable-length, continuous alphanumeric barcode. It can encode
all 128 ASCII characters.
Code 128 barcode
consists of blank space, start mark, data area, check character
and terminator. It has three subsets, namely A, B and C, which
can represent different character sets. It can also be used to
achieve multi-level encoding through the selection of starting
characters, code set characters, and conversion characters. |
It can encode all
128 ASCII characters, including numbers, letters, symbols and
control characters, so it can represent all characters on the
computer keyboard.
It enables
high-density and efficient data representation through
multi-level encoding and can be used for automatic
identification in any management system.
It can be
compatible with the EAN/UCC system and is used to represent the
information of the storage and transportation unit or logistics
unit of the commodity. In this case, it is called GS1-128. |
