An electronic signature system using wired/wireless communication is provided to introduce the electronic signature system including an algorithm for compressing and transmitting electronic signature data to the existing payment system without using an additional device. An electronic signature system(200) includes a touch screen(201), a controller(202), a data compressor(203), a payment device matching unit(204), a wired/wireless communication unit(205) and a display(206). The payment device matching unit receives a signature request message from the existing payment system(210) and requests the controller to prepare signing. The controller displays particulars required for signing. When a user signs on the touch screen, an image corresponding to the signature is transmitted to the controller as analog data. The image is compressed by the data compressor. The controller transmits the compressed data to a payment system server. The controller stores the compressed data. |
