Abstract
One characteristic of electronic labels is that they can be read and written on without electrical contact through the communication coil (1). The reading heading is then positioned at some distance and communicates with the label through electromagnetic waves. When these labels are placed on metallic objects, reading becomes difficult even impossible because of the dispersion of the waves in the object. To overcome this drawback, the invention proposes the adding of an electromagnetic conductive element (3, 3′) to the coil (1) in order to insulate it (1) and enhance the reception quality.
