CARD HAVING FINGERPRINT SEALING UNIT AND METHOD FOR EXTRACTING FINGERPRINT

摘要

PURPOSE: A card having a fingerprint sealing unit and a method for extracting a fingerprint are provided to obtain a fingerprint image of a user by providing a card having a fingerprint sealing unit at the upper side surface thereof and sealing a fingerprint to the fingerprint sealing unit and penetrating a light to an image of the remaining fingerprint. CONSTITUTION: A card reader(20) having a fingerprint extracting function is connected to a main system and performs a certification of a user using a user's fingerprint. A light emitting unit(21) as a single light emitting diode, a laser diode, a light emitting diode array or a laser diode array emits a light or a frequency for extracting a fingerprint sealed in a fingerprint sealing unit(11) of a card(10). A fingerprint extracting unit(22) having a plurality of sensors(23) converts a format of a sealed fingerprint at a corner of the fingerprint sealing unit(11) into an image or calculating data based on a variation of an electric charge in accordance with a light emitted from the light emitting unit(21) and a variation of an electric characteristic of the sensors(23) penetrating the fingerprint sealing unit(11) of a card(10) and being arrayed at a responding surface of the light emitting unit(21).
