Abstract
In order to increase the efficiency of a production process a new method is presented. Thereby a flow of items is generated in a production system. Electronic devices that are attachable to the items are used for tracking the items. An identification of a first electronic device attached to a first item is read out. The identification is forwarded to a computer system that steers the flow of items. Due to a reception of the identification by the computer system, a transport status indicating authorization or prohibition to process the second item is set. The transport status is then transmitted to a second electronic device with an authorizing signal that is sent from the computer system to the second electronic device. The second electronic device contains a signal receiver circuit for receiving the authorizing signal and the second electronic device is attached to the second item.
