Abstract
Abstract A device is disclosed which is capable of determining whether a person using a credit card is the true owner of the card. The person places his hand on a surface of the device. Light radiation is transmitted through the hand and received by a radiation sensitive device such as a photocell. The photocell is mounted opposite the light source and on the obverse side of the hand. The transmission intensity pattern, amplitude, and other characteristics of this radiation passing through the hand are then compared with previously determined values for this person''s hand. These previously determined values may be coded within a credit card or other similar medium. If the coded values and the signal received by the photocells are the same, the person being tested is the correct individual and if they are not the same, he is not the correct individual.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
An apparatus for determining the characteristics of a human body member and comparing it with an electrical signal obtained from an indicia bearing medium standard means adapted to receive the member whose characteristics are to be determined, a source of radiation, means mounted for irradiating the member with said radiation, means for receiving radiation passing through the member as a result of said irradiation a plurality of photocell means arranged in a predetermined pattern for converting the received radiation to an output electrical signal, and means for comparing the output signal to said standard signal.
Claim 2
Independent Claim
95 words
An apparatus for determining the characteristics of a human body member and comparing it with an electrical signal obtained from an indicia bearing medium standard means adapted to receive the member whose characteristics are to be determined, a source of radiation, means mounted for irradiating the member with said radiation, means for receiving radiation passing through the member as a result of said irradiation a plurality of photocell means arranged in a predetermined pattern for converting the received radiation to an output electrical signal, and means for comparing the output signal to said standard signal.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1 wherein one side of the member is irradiated and the radiation that is received is from the opposite side of the member.
Claim 4
Dependent Claim
16 words
The apparatus of claim 2 wherein the radiation comprises radiation in the visible and infrared ranges.
Claim 5
Dependent Claim
12 words
The apparatus of claim 2 wherein the member comprises a human hand.
Claim 6
Dependent Claim
27 words
The apparatus of claim 4 wherein means are provided which are actuated when the output signal corresponds to the standard as a result of said comparing means.
Claim 7
Dependent Claim
27 words
The apparatus of claim 5 wherein means are provided to print said indicia of said indicia bearing medium when said output signal corresponds to the standard signal.
Claim 8
Independent Claim
78 words
A method of determining the characteristics of a human body member comprising a steps of illuminating a surface of a member with a non-destructive source of radiation receiving the radiation passing through the opposite surface of the member as a result of the irradiation on a plurality of photocells arranged in a predetermined pattern to convert the received radiation to an output signal and comparing the output signal with a standard signal obtained from an indicia bearing medium.
Claim 9
Independent Claim
78 words
A method of determining the characteristics of a human body member comprising a steps of illuminating a surface of a member with a non-destructive source of radiation receiving the radiation passing through the opposite surface of the member as a result of the irradiation on a plurality of photocells arranged in a predetermined pattern to convert the received radiation to an output signal and comparing the output signal with a standard signal obtained from an indicia bearing medium.
Claim 10
Dependent Claim
25 words
The method of claim 7 wherein the non-destructive source of radiation is a source of radiation which includes radiation in the infrared and visible ranges.
Claim 11
Dependent Claim
12 words
The method of claim 7 wherein the member is a human hand.
