## Important distinctions
The main homepage toolkit runs barcode calculations in the browser. The separate legacy Universal Barcode Generator uses server-side generation. A valid check digit does not prove that an identifier has been assigned, registered or approved. Test final printed output with its intended scanner and workflow. Product listings contain seller information and dated price references; verify current details with the seller.
