PHYSICAL PRESENCE DIGITAL AUTHENTICATION SYSTEM (TRANSMISSION AND ROUTINE)

Title:

PHYSICAL PRESENCE DIGITAL AUTHENTICATION SYSTEM (TRANSMISSION AND ROUTINE)

Document Type and Number:

WIPO Patent Application WO2001057620

Kind Code:

A3

Abstract:

The interactive authentication system allows a consumer to interact with a base station, such as broadcast media (11) or PC (14), to receive coupons, special sales offers, and other information with an electronic card (10). The electronic card (10) can also be used to transmit signal that can be received by the base station to perform a wide variety of tasks. These tasks can include launching an application, authenticating a user at a website, and completing a sales transaction at a website (e.g., by filling out a form automatically). The interaction between the base station and the electronic card is accomplished by using the conventional sound system in the base station so that a special reader hardware need not be installed to interact with the electronic card. The user is equipped with an electronic card that can receive and transmit data via sound waves. In the various embodiments, the sound wave can be audible or ultrasonic (which can be slightly audible to some groups of people).
