Hardware

Odoo Point of Sale supports integration with a variety of hardware, including payment terminals and cash drawers, as well as customer displays, scales, barcode scanners, ePOS printers, and in-store electronic shelf labels.

Units of measure

European regulations

When using scales in commercial transactions, the database integrated with a scale must be configured to meet specific European requirements. This includes supporting at least three decimal places for accuracy and using proper rounding for units of measure, such as kg instead of generic units.

If the database is not compliant, a red (scale) icon displays as a warning. Click this icon to view the reasons for non-compliance and then select Apply changes to automatically apply the necessary changes to the settings. Once the database meets all regulatory requirements, the (scale) icon turns green.
