система маркировки товаров
The marking code contains unique data for every product item and is represented as a GS1 DataMatrix 2D barcode. The Belarusian marking code consists of the following data blocks:
- 14-digit GTIN (Global Trade Identification Number) generated by GS1
- 8-digit individual serial number of the product item generated by the Belarusian operator (SIS “Electronic Mark”)
- 4-digit verification code generated by the Belarusian operator (SIS “Electronic Mark”)
To generate a GS1 DataMatrix code, product groups are separated with dedicated reserved delimiting characters (GS1 application identifiers).
