SMART CARD WITH ONE TIME PASSWORD GENERATION AND DISPLAY

摘要

A smart card equipped with a function for generating and displaying an OTP is provided to generate and use the OTP in case of necessary without help of an external device by mounting and connecting a module for generating the OTP with an IC module. The smart card(300) stores a personal authentication number inputted from a user of the smart card and data for generating the OTP in a non-volatile memory. An OTP generating module(320) generates OTP information by including a program for generating the OTP and linking with the IC chip depending on an operation request signal inputted from the user. A display module displays the generated OTP information by the operation request signal. A switch(350) generates the operation request signal for generating and displaying the OTP. The display module includes a display device(331) for displaying the OTP information and a display operating module(330) for operating the display device by receiving the OTP information from the OTP generating module.
