For a client i want tobe able to use external weighted products where the price is included in the barcode.
The format of these barcodes include a price check digit (pdc) like this (this is a fictional barcode):

flag - plu -   pcd - price -  check digit

28     0450   7      00799  3

In the barcode nomenclature of standard Odoo there seems no way to handle price check digits (I also checked the source code and found nothing).

Did I miss anything, or is there really no way to support this?
Does anyone know about a module that adds support for these kind of barcodes?
