Abstract
An RF identification label includes a selectively activatable battery and control and RF generating circuitry which is coupled to the battery. The battery includes two separate components which are brought together in operative contact to activate the battery and provide power to the control and RF generating circuitry. The preferred embodiment of the control and RF generating circuitry includes a programmable integrated circuit with contacts which permit programming by a user to define the identification signal which is generated.
