The invention relates to a resonant label () which is designed to be directly applied to a data carrier () that is provided with a metallization, such as a CD, DVD or an MO disc. To facilitate and/or improve the electromagnetic remote identification of said label using a frequency in the RF range, the label is equipped with an outer coil () that forms part of an electric resonant circuit and runs essentially around the outer edge of the data carrier (). The resonant label () is preferably configured on a transparent substrate, so that it blends in with the data carrier () and permits an impression on the latter () to remain visible. The resonant label () can either be used as an entity in itself or in a particularly advantageous manner as a type of wave collector or booster for a smaller RFID label () that is located on the same data carrier. The label thus permits the remote identification of the RFID label (), even if the data carrier () is completely metalized. Finally the resonant label can also be provided with a semiconductor chip and configured as an RFID.
