Yes. Moreover, Megaventory is compatible with any kind of hardware device: you may use any barcode scanner with Megaventory to fill in the rows of documents (eg. goods in, goods out, sales/purchase orders).
Note that any typical barcode scanner which can connect via USB, WiFi or Bluetooth to the laptop or desktop which Megaventory is accessed from will do.
To enable this, please check the option "Products are added using a barcode scanner" when creating a document. You will then be able to scan each product code and the system will automatically move on to the next row, enabling the filling of rows in an automatic manner.
