This symbology is only numeric and offers a very high density of characters per inch due to 
its interleaved encoding system. The decoding is very easy even if the symbols are poorly 
printed. These advantages make it very popular for industrial applications. 

But to avoid missing characters when scanning is incomplete, it has to be used with fixed 
lengths (see pages 28 or 29) or variable lengths with a check digit (see page 30). 

 

The characters are interleaved (always paired), therefore it is necessary to define 
whether the number of significant characters is odd or even.
