Bio-metric smart card, bio-metric smart card reader, and method of use
First Claim
1. A self-contained apparatus configured for a user thereof to operate with at least some account number transaction devices that are adapted to receive and process account information associated with credit card and debit card transactions, the apparatus comprising:
- a body sized with substantially a same shape, form factor, and properties of a plastic credit card integrated with a smart card for use with the account number transaction devices, the body having at least one transaction independent account number integral thereto;
one or more electronic circuits disposed within the body, the one or more electronic circuits including;
a display configured to display a dynamic security key code;
a bio-metric interface configured to receive bio-metric data;
a memory configured to electronically store bio-metric data associated with the user and the at least one transaction independent account number, a processor that when activated is configured to;
compare the bio-metric data received from the bio-metric sensor with bio-metric data stored within the memory, wherein the bio-metric data is associated with the user of the apparatus;
increment a transaction counter if a positive comparison is found between the stored bio-metric data and the bio-metric data received from the bio-metric sensor;
generate an encryption key from the stored bio-metric data;
transmit the encryption key to the account number transaction devices along with the transaction independent account number; and
a power source disposed within the body, the power source configured to power at least some of the electronic circuits.

Abstract
A system for increasing transaction security across existing infrastructure is provided. A user bio-metric sensor device is integrated into a credit or debit card. A display unit provides a key, preferably encrypted, upon successful utilization of the sensor device. Included in the key generation mechanism is an indicator of the transaction number or other sequential count indicative of card use. An authorization service decrypts the key in a manner at least partially dependent upon a second sequential count maintained in sync with the first count to determine whether the use is authorized. In one embodiment, a separate credit card reader may be configured to read conventional credit cards, smart cards, and credit cards incorporating such bio-metric sensor devices.

6. An apparatus configured for a user thereof to read data from at least one card such as a credit card or a smart card, the apparatus comprising:
-
a body configured to receive at least a portion of the electronic transaction card card therein to read data therefrom;
a display configured to display a dynamic security key code;
a bio-metric interface configured to receive bio-metric data;
a memory configured to electronically store bio-metric data associated with the user and at least one transaction independent account number received from the electronic transaction card; and
a processor that when activated is configured to;
compare stored bio-metric data associated with the user thereof with bio-metric data received from the bio-metric interface;
compare stored account data associated with the user thereof;
increment a counter if the users bio-metric data associated with the at least one transaction independent account number matches the stored data;
generate an encryption key partially from the stored bio-metric data; and
transmit the encryption key to one or more account number transaction devices along with the transaction independent account number.

7. A method of processing a transaction associated with a transaction independent account number associated with a user thereof, the method comprising:
-
retrieving the transaction independent account number from a card;
receiving bio-metric authentication data from the user of the card from a bio-metric sensor;
comparing the bio-metric authentication data with stored data associated with the transaction independent account number;
determining if the user is authorized to use the card;
if the user is authorized to use the card;
incrementing a transaction counter;
generating a security key in a manner at least partially dependent upon a count of the transaction counter, and at least partially dependent upon the user'"'"'s bio-metric authentication data; and
transmitting the security and the transaction independent account number to an authorizing authority for processing thereof.
