The application is intended for barcode readers, e.g. Zebra TC21. The application works only in cooperation with the Frutis information system. In the first version, it is used for checking pallets returned to the warehouse. User can load palette label. The application then displays information about the pallet, and the user confirms or rejects the return of the pallet to the warehouse by visually inspecting the pallet and recalculating the number of cartons. Subsequently, if the status of the pallet is positively confirmed, a so-called partial inventory will be started on the server.
