    摘要: A smart card comprises a microcontroller, a memory unit, a storage unit, and a communications unit. The smart card may be connected to a terminal, which is in turn may be connected to a host computer and/or a network. The smart card is configured to initiate communications with the terminal, which enables the smart card to control the terminal, host computer, or network and to access the resources connected to the terminal, host computer, or network. A communications protocol defines the commands that the smart card can send and allows the smart card to communicate using asynchronous or logical asynchronous communication.

    摘要: Smart (integrated circuit) card supervisory control and data acquisition. Industrial processes may be controlled by one or more smart cards. Signals may be received from an industrial process by the smart card, the signals may be processed by the smart card, and control signals may be sent from the smart card to the industrial process in response to the processed signals. The smart card may provide security/tamper resistance for proprietary information associated with the industrial process. Control of the industrial process may be distributed among one or more smart cards at particular process points to receive sensed process parameters and to send control signals to implement process actions.
