Code 25 is a very simple numeric code which is
able to display digits from 0 to 9. The code is primary used in industry and is
also known as Code 2 of 5 or Code 25 Idustrial. Code 25 has no built in
check digit. The code is some years old and it takes up so much space that today it is not often used.
Code 25 Interleaved is a special type of Code 25
that is also a numeric code able to display digits from 0 to 9. The code is also known
as Code 2 of 5 Interleaved.It has no built in check digit.
The advantage of Code 25 Interleaved is that the code uses self-checking and it is very
compact so it does not need much space like the simple Code 25. Code 25 Interleaved is
only valid if there is a even number of digits. To display an odd number of digits
you have to add a zero to the beginning (123 becomes 0123) or you may use your
own check digit.
An example for the difference of Code 25 to Code 25 Interleaved:
The digits 123456 will be codes. The result as Code 25 Idustrial is as follows:
And here the same digits 123456 coded as Code 25 Interleaved:
ActiveBarcode always uses the proportion 3,0:1.
