In the area of production and logistics, various components and work steps can be simplified through the use of RFID labels.
The individual product or general cargo can be registered automatically during goods receipt and goods issue. This prevents incorrect loading.
With regard to warehousing, inventory checks can be carried out at the push of a button. A fast pallet localisation as well as an automatic of all incoming and outgoing goods is also possible.
In addition, an efficient swap body identification can be realized by automatic access recognition and real-time data transfer to a transport planning system. In this way, optimized container deployment planning takes place and the suppliers already know where their freight is to be loaded when they arrive.
By using RFID technology, personnel costs can be reduced and error rates in order fulfillment can be reduced. It can also reduce annual inventory costs and improve the quality of inventory information.
RFID transponders are characterized by sensitive electronics. Goods with a high proportion of metal or water cause a disturbance of the electromagnetic field, whereby the data often cannot be read out completely or only incorrectly.
In addition, the self-adhesive labels are equipped with an adhesive that is not fully compatible with all substrates or is not resistant to moisture or chemical influences. This can lead to a reduced adhesive strength, so that the chip becomes detached from the carrier or the goods and can lead to the loss of the data.
In addition, RFID tags in their usual form are usually not resistant to shocks or vibrations, so that damage within the storage and transport chain is possible.
(A) Backgrounds + application of RFID tags: The material on which the transponder is attached to the workpiece or packaging unit has a major influence on its functionality. The function of the RFID system can be severely impaired if an unfavourable material such as metal is used.
(B) A spacer material is therefore always used if the application material cannot be applied directly to the transponder. This can be a self-adhesive foam, for example.
(C) The air interface material is the material located between the transponder and the read & write device (D). This can be, for example, an applied protection of the transponder up to a partition wall, which impairs the writing & reading range.
The reading range is influenced differently depending on the material. In the worst case, the transmitting power of the transponder can even be completely absorbed or reflected.
Sensitivity to water and liquids: Reflections when sending and reading data or complete defect of the electronics.
Mechanical loads: Damage and detachment of the transponder due to shocks, vibrations, pressure, friction or shear forces.
Chemical loads: E.g. by oils, greases, cleaning agents, lubricants, alkalis, acids, surfactants and solvents.
Thermal loads: Damage caused by very high or low temperatures on site.
Weather-related influences: Influence of rain, fog, humidity, frost or sea air on communication between transponder and reader/writer.
