Abstract: PURPOSE: A communication device and method using flickering of a display unit of a mobile terminal are provided to incur little costs for installation or usage by simply downloading and executing only control software for payment or authentication through a mobile terminal. CONSTITUTION: A mobile terminal(100) transmits an optical signal. A light receiving unit(200) recognizes the optical signal received from the mobile terminal(100). A controller(110) controls the mobile terminal(100). A memory unit(120) stores a program and data. A display unit(130) displays a character or an image. A light receiving sensor(210) senses flickering of the display unit(130) and a change of its color. An optical/electric signal converter(220) converts a received optical signal into a digital electric signal and transmits it to a controller(230). The controller recognizes the electric signal as information, and processes and transmits it to an external unit or to the Internet. The mobile terminal(100) transmits information by using a flickering period of the display unit(130) and the light receiving unit(200) receives information by sensing a change period of light transmitted from the display unit(130).
