Typically, a brand uses one POS type across all of the brand's locations. This setting is configured in the Cockpit section of the Platform.
When individual locations are created under Settings > Locations in the Platform, there is an option to configure a POS type. This ONLY needs to be configured if the location's POS type is different from the brand's POS settings in Cockpit. When this is left blank, the settings from Cockpit are pulled to the individual location.
