Beschreibung
Zusammenfassung:A metal screened ( 13 ) electronic labelling system having at least one information bearing electronic coded label including a label coil ( 12 ) and an interrogator including a transmitter coil ( 9 ). The system relies on a magnetic field coupling link containing the transmitter coil ( 9 ) and the label coil ( 12 ) for obtaining information from the label. The coupling link is arranged such that it operates in the near field thereof and substantially none or at most a minority of the magnetic flux which excites the label coil ( 12 ) also links the transmitter coil ( 9 ).
