An authorization code is entered into a card terminal reader from a security card. The authorization code is first entered into a card and stored in a secret memory location or stored into or onto the card with a alternate element. A characteristic physical state of an element on the card is temporarily changed from a first state to a second state. When the card is inserted into a card reader terminal within a pre-defined period of time, the authorization code is transmitted to the card reader terminal and the state is reset from the second state to the first state.
