Good Morning.

I want to read bar codes used in supermarkets for fractionated products. These codes begin with an identifier and then bring the data from product and price, ending with the code verifier.

An example: 2100010015990.

21 is the identifier

0001 is the orange code

001 599 price is $ 15.99

0 is the verifier.

I have in Odoo the option to define the rules of bar codes used in the POV, but I can not make it work. With fixed bar codes, it works perfect, but with no variables.

I am grateful to anyone who can help me, if there is any documentation or video that explains a little more about it.

I am using the online version of Odoo.
