摘要

PURPOSE: A Blue-tooth typed portable credit card reader and a system for inquiring a credit card are provided to print a sales slip by the data communication with a main credit card inquiring terminal at a counter desk in a Blue-tooth method. CONSTITUTION: A Blue-tooth communication module(100) communicates with the main credit card inquiring terminal. A data signal processor(105) processes the data communicating with the main credit card inquiring terminal via the Blue-tooth communication module(100). A voice signal processor(110) processes the voice data communicating with the main credit card inquiring terminal via the Blue-tooth communication module(100). An A/D(Analog/Digital) converter(115) converts an analog voice signal into a digital voice signal and outputs it to the voice signal processor(110). A D/A(Digital/Analog) converter(115) converts the digital voice signal into the analog voice signal and outputs it to an ear microphone. A memory(135) stores a driver program of a device and temporarily stores the credit card information read from the card reading part(155). The card reading part(155) reads the card information of the credit card.
