MULTI-PURPOSE USER AUTHENTICATION DEVICE

摘要

A multi-purpose user authentication card that combines the functions of one-time passcode generator, storage components (16, 32) and smart card components (36) in a single compact device. A microprocessor (12) generates the one-time passcode, which is displayed on a screen for 30-60 seconds. A smart card (36) performs basic encryption and decryption to allow the user to gain access to a protected external resource. An independent, rechargeable power source (14) allows the card to switch between an active mode, a standby mode and off mode.
