PURPOSE: A device for interfacing with a portable terminal user is provided to be supplied as transceiving data with a portable terminal and an additional external extender, thereby storing a large amount of data collected through the portable terminal as using position information of the portable terminal. CONSTITUTION: An input unit(110) interfaces with an external key input unit(10). A display driver(120) drives a display(20). A portable terminal connector(140) interfaces with a portable terminal(40). A controller(160) inputs inputted data through the input unit(110) from the key input unit(10), processes the data in protocol, and transmits the processed data to the portable terminal(40) through the portable terminal connector(140). The controller(160) receives data processing results on the inputted data through the portable terminal connector(140), processes the results in protocol, and transmits the processed results to the display(20) through the display driver(120).
