The information carrier ( 1 ) contains a storage unit ( 9 ), an integrated circuit ( 10 ) and a first and a second coupling element ( 31, 32 ). Said coupling elements ( 31, 32 ) are intermediate in the transfer of data and energy from a base station ( 50 ) to the integrated circuit ( 10 ) and vice versa. Between the base station ( 50 ) and said coupling elements ( 31, 32 ) the transfer of data and energy is contactless, and preferably by capacitive coupling. Between at least the first ( 31 ) of and preferably both of the coupling elements ( 31, 32 ) data and energy are transferred by means of capacitive coupling. The base station ( 50 ) is preferably incorporated in an apparatus ( 40 ) further containing the reading device ( 60 ) of the storage unit ( 9 ). To facilitate the capacitive coupling, the base station ( 50 ) contains a first and a second capacitor plate ( 54, 55 ). The information carrier ( 1 ) and the apparatus ( 40 ) with the base station ( 50 ) containing said capacitor plates ( 54, 55 ) together constitute the system, which is suitable for copy protection of the information on the storage unit ( 9 ).
