The invention provides a conditional access system, wherein a conditional access client in a terminal has minimal functionality while a smartcard for use in the terminal incorporates user interaction and content authorisation functionality. The interface for user interaction between the smartcard and the conditional access client is generic. The invention enables addition or modification of conditional access functionality to the conditional access system by upgrading or replacing the smartcard, without requiring modifications to the terminal.
