METHOD FOR PROVIDING A ONE TIME CARD USING DYNAMIC NUMBER AND CODE IMAGE, CARD AND SMART PHONE

摘要

PURPOSE: A method for providing a disposable card using a card and a smart phone is provided to offer safe card transactions by creating a disposable card number by recognizing the dynamic number and a code image. CONSTITUTION: An output module(115) electrically output a dynamic number by locating on an upper or a lower insulation medium unit. An input module(120) receives a dynamic number output request signal from a user by locating on the upper or the lower insulation medium unit. A generation module(135) creates a dynamic number by inserting a dynamic seed value dynamically determined as a fixed seed value based on a dynamic number output request signal in to a padding generator. A control module(145) is inserted between the upper and the lower insulation medium unit in order to output the dynamic number to the output module.
