CARD TYPE DEVICE FOR GENERATING ONE TIME PASSWORD

摘要

PURPOSE: A card type OTP generating device is provided to increase the readability of a password based on high emitting efficiency by forming a display unit in an OLED. CONSTITUTION: An electric signal generating unit(200) generates an electric signal by external pressure. An OTP(One-Time Password) generating unit(300) generates an OTP based on an OTP generating algorithm according to the generation of the electric signal. A display unit(500) is composed of an OLED(Organic Light Emitting Diode). A controlling unit(400) displays an OTP on the display unit. A switch switches power supply of a power unit(100). A switch controlling unit controls an operation of the switch.
