Holographic credit card with automatical authentication and verification
First Claim
1. A banking system, utilizing the existing communication channels and the holographic angular-invariant credit card with self-authoriztion and authentication, wherein at a command signals is produced when authorized user presents unique identification to the approval device, the latter comprising:
- an input element for angular invariancy in the form of a transparent window against which the user presents the unique identification and rotates it for angular alignment with the said identification previously stored in form of hologram,a matched optical filter in the credit card upon which the unique identification of said authorized user is stored in a Fourier holographically encoded form, or in the form of Fourier-hologram;
means for illuminating said unique identification with coherent beam at said transparent window;
means for projecting upon said optical matched filter the reflected beam of said coherent light having been encoded by said unique identification at the window; and
means for focussing and registering the correlation signal being formed in the process of comparing the stored indentification with the presented identification during rotation, and for generating the command signal only when the correlation signal is unambiguously present;
a communication line to the bank computer,means for pre-storing of the identification in the said matched optical filter, the latter being produced in the form of a generalized hologram,means of comparing the sheltering information, being prestored in the said "generalized" hologram in the computer,means of providing the command feed-back signal from the computer.

Abstract
A holographic credit card that uses a matched optical filter to store in form of a hologram a unique identification such as a fingerprint of the authorized user, a source of coherent light that provides the illumination, and the input element in the approval device for providing the angle-invariance, possessing the form of the transparent window, against which the user places and rotates the same fingerprint, and the registering device for registering the correlation optical signal between the stored fingerprint and presented fingerprint to generate a signal to activate the device when, and only if, a positive correlation exists between the presented and the registered fingerprints. A two-stage holographic credit card using the "generalized matched optical filter", wherein the additional information for authorization is stored in the reference beam during the preparation of the said filter, the angular invariance is provided by the said means and the means of second-stage approvement, utilizing the existing banks communication lines, are also provided. A three-stage holographic credit card, using the "generalized matched optical filter", wherein the additional information for verification is stored in the reference beam during the preparation of the said filter, the angular invariance is provided by the said means, the means for bank'"'"'s computer approving procedures, including the automatic feedback are provided, and the means of additional second-stage optical comparison are also supplied.
