On Card Display of Data From Secured Chip

A retrofitted smart card comprising:

• a certified smart card chip;
• a display;
• retrofitted emulation circuitry operative to enable said certified smart card chip to communicate information to said display notwithstanding that said certified smart card chip is configured for communication only with an external read/write device;
• and
• retrofit firmware for operating said certified smart card chip at least in the absence of an external read/write device, said retrofit firmware including mode of operation identification functionality, which enables the certified smart card chip to distinguish between operation in communication with the external read/write device and operation in a stand alone mode.

A retrofitted smart card comprising:

• a certified smart card chip including secure access circuitry permitting communication with a certified smart card chip reader;
• a display;
• retrofitted emulation circuitry operative to enable said certified smart card chip to communicate information to said display and also to communicate with said certified smart card chip reader;
• and
• retrofit firmware for operating said certified smart card chip at least in the absence of an external read/write device, said retrofit firmware including mode of operation identification functionality, which enables the certified smart card chip to distinguish between operation in communication with the external read/write device and operation in a stand alone mode.

A method of providing a smart card with a card-mounted display function comprising:

• providing a certified smart card chip;
• associating a display with said certified smart card chip;
• emulating an external read/write device to enable said certified smart card chip to communicate with said display notwithstanding that said certified smart card chip had originally been configured for secure communication only with an external read/write device;
• supplying a voltage to said certified smart card chip enabling the certified smart card chip to run retrofit firmware installed thereon including mode of operation identification functionality, which enables the certified smart card chip to distinguish between operation in communication with the external read/write device and operation in a stand alone mode.
