A smart card comprising a housing including two opposing major portions that are connected together; an integrated circuit supported in the housing, the integrated circuit including a microprocessor and a random access memory, the random access memory being used to store data; a battery supported in the housing and having first and second terminals, the first terminal being coupled to the integrated circuit; and a conductor coupling the second terminal of the battery to the integrated circuit to complete a circuit, the conductor being supported by the housing such that separation of one of the portions of the housing from the other portion opens the circuit and breaks connection of the battery to the microprocessor so that data held in the random access memory is erased.
