PURPOSE: A system and a method of cardless secure credit transaction processing are provided to extract the unique numerical information from a fingerprint. CONSTITUTION: The method comprises the steps of scanning the fingerprint by a scanner(1102), enhancing the generated image(1104), restoring the enhanced image by correcting a form distortion of the image and applying the reverse-filtering(1106), making the restored image into binary(1108) by converting the image into a black/white image, making the binary image thin(1110), detecting a core point from the thinned image(1112), detecting the minutiae within a fixed radius of the core point(1114), and extracting a value by calculating a relation between the minutiae and the core point(1116).
