SMART CARD EQUIPPED WITH DISPLAY TOOL AND POWER SUPPLY DEVICE

摘要

PURPOSE: A smart card equipped with a display tool and a power supply device is provided to facilitate design and manufacture of a PCB(Printed Circuit Board) by separating IC devices installed on the PCB into each function group. CONSTITUTION: A circuit pattern is printed on the PCB(21). A main circuit(22) device stores and processes various kinds of data by installing on the PCB. An external contact electrode(23) is electrically connected to the main circuit device. The power-supply(24) applies voltage to the main circuit device. A keypad(25) inputs user's command to the main circuit device. A display panel(26) displays the data provided by the main circuit device. An I/O(Input/Output) circuit device(27) processes/inputs the user's command inputted from the keypad to the main circuit device and operates the display panel under the control of the main circuit device.
