The gs1-qr-code bar code type is a variant of the qr-code.

The GS1 QR code is identical to the QR code, except:

  • Values are encoded with a leading FNC1 character.
  • The Code Value property is scanned for octal escapes. The FNC1 character is expected to be encoded by the ASCII “group separator” character (decimal 29) as an octal escape “\035”. For example, “3019\03521123456789012” is encoded as FNC1, 3019, FNC1, 21123456789012. Literal backslash characters must be quoted by prefixing with a backslash, so that ‘\’ must be encoded as ‘\\’.
