Short Description
The GS1 Data Matrix uses a special start combination to differentiate the GS1 DataMatrix symbol from other Data Matrix ECC 200 symbols. This is achieved by using the Function 1 Symbol Character (FNC1) in the first position of the encoded data. It enables scanners to process the information according to the GS1 System Rules.

Bar Code Properties
