You need to use a barcode scanner that can read gs1 barcodes, when you read the barcode in the hexadecimal text tool, you should see what symbol is used to divide between sections and then build your logic.

All the documentation I found says that the sections must be separated by a special symbol, this symbol being determined by the barcode generator. It is explained that "GS" is most often used, but it cannot be used when printing "QR code". I have not found out which symbol can be used by default, but it became clear that when printing in "QR code" is used different from the standard symbol. Maybe it's a good idea to ask the country that generates the barcode

I tried to make a general parser for all GS1 QRReader, but I think it's not that easy, because each Barcode reader must be programmed to replace the FNC Char with a readable Char. 

I will Contact J4L "one of the Links which you gave me", but they read code from an image not data, hopefully they will have a solution.

anyway thank you very much for your follow up and help.

 

Regards
