ABSTRACT:
An information carrier contains a storage unit, an integrated circuit and a first and a second coupling element. The coupling elements are intermediate in the transfer of data, and energy from a base station to the integrated circuit, and vice versa. Between the base station and the coupling elements, the transfer of data and energy is contactless, such as by capacitive coupling. Between at least the first and/or both of the coupling elements, data and energy are transferred by the of capacitive coupling. The base station may be in an apparatus containing a reading device of the storage unit. To facilitate the capacitive coupling, the base station contains first and second capacitor plates. The information carrier and the apparatus with the base station containing said capacitor plates together constitute the system, which is suitable for copy protection of the information on the storage unit.
