Why won't I see the product description the scanned product in the App?

If, after scanning the barcode of a product, no article description appears in the App, there can be several reasons for this:

• The barcode does not exist
• Or the code does not comply with the rules drawn up for that purpose
• The barcode is somehow 'damaged' (parts of the code are missing)
• The wholesaler did not enter the article description in BarTrack
