DISPLAY DEVICE WITH MAGNIFICATION FUNCTION FOR LIMITED-USE PASSWORD

摘要

The device has a display i.e. LCD type display, exhibiting two lines of characters, where each line is dedicated respectively to an instruction line and one time password (OTP) number line. Magnifying units carry a magnification function of the display of an OTP number by partially distributing its display over the lines of characters dedicated to the OTP number and by partially distributing its display over the lines of characters dedicated to an instruction. The magnification function is uniquely realized on height of each character. An independent claim is also included for a program comprising instructions for implementing a device for displaying a one time password number.
