An electronic label comprising at least one electronic component (2) and an antenna in the form of a coil (1). The label information can be read without electrical contact by a reader device which activates the label by transmitting an electromagnetic field (F) towards one face of the label. The label then transmits its information to the reader. When such labels are placed on metallic objects, reading becomes difficult even impossible as a result of the dispersion of waves in the metallic object. By placing a magneto-reflective element (3) either around or behind the electronic component and coil, the magnetic flux reaching the coil is enhanced.
