PURPOSE: A non-contact type signature pad is provided to predict disease contagion of a user due to indirect contact by inputting a signature without physical contact. CONSTITUTION: A frame(40) includes a virtual signature space area. A camera(10) is installed within the frame and generates a photographed image in the virtual signature space area. An image processing unit calculates a location coordinate of a signature input unit by analyzing the photographed image. The image processing unit generates signature pattern data which converts the location coordinate of the signature input unit into a transparent location coordinate of a display device.
