Hi, Odoo supports any sequence as barcode, this way you can always define your own barcode format for internal use. Apart from scanning products, you can perform actions such as:

- Receive products (pick in orders)

- Dispatch products (pick out orders)

- Inventory adjustments

- Internal inventory movements

Hope this helps you.

See https://github.com/odoo/odoo/blob/14.0/addons/web/controllers/main.py#L2077 for the full list of what types are supported:

Accepted types: 'Codabar', 'Code11', 'Code128', 'EAN13', 'EAN8', 'Extended39',
