The picked receptacles are forwarded to an unloading station where an identifier of each item is identified at the unloading stating and the identifier of the item married with the transport receptacle into which the item is placed. The transport receptacles are tracked from the unloading station according to the identifier of the item in that transport receptacle and movement of the transport receptacle.
