Description
Provides the bar code area. It consists of bars and spaces of one module (minimum unit
consisting on bars and spaces).
This check character is composed with 7 bars and spaces consisting with 18 modules,
and it is set between 2 data characters. It is used to check if the read data is correct
or not by putting the value calculated with the certain formula on just before the stop
character for re-calculation.
Functions as a check character or segment identifier, too, which makes symbols to be
easily recognized. It consists of five elements having 15 modules.
Has the (n, k) structure. "n" indicates the number of modules and "k" indicates that of
bars and spaces that make up the character. As shown in the figure above, the data
character is arranged so as to facing to the adjacent finder pattern (toward the arrow
direction).
The minimum value of bar code height is 34 times as high as the module width. For GS1
DataBar Expanded Stacked, the minimum value of one step of bar code is 34 times as
high as the module width.
