The Code 25
barcode is a barcode invented by the American company Intermec
in 1972.
It is composed of
black bars and white spaces of unequal width and is used to
represent digital information. Its predecessor was the idea of
using barcodes to mark envelope addresses, proposed by Kermode
in the UK in 1932.
The application of
Code 25 barcode is mainly in the representation of digital
information, such as airline ticket numbers. It can also be used
in combination with other types of barcodes, such as Industrial
25, Cross 25, Matrix 25, etc.
The format is fixed
and consists of a set of dark and light straight lines with
widely different reflectivities, used to represent a certain
data structure.
The Code 25
barcode can only encode ten digits from 0 to 9, while the
Interleaved 2of5 barcode can encode numbers of any length as
long as they are an even number.
The Code 25 barcode
is a double-width barcode that only supports numeric characters
and the code length is variable.
Each coded character
consists of five lines, two of which are wide bars used to
represent numbers.
The starting and
ending characters must be A, B, C or D.
