An authorization code is entered into a chip card terminal from a chip card. The authorization code is first entered into a chip card and stored in a secret memory location. A state on the chip card is temporarily changed from a first state to a second state. When the chip card is inserted into a chip card terminal within a pre-defined period of time, the authorization code is transmitted to the chip card terminal and the state is reset from the second state to the first state.
