Abstract
A transaction authentication card uses a biometric input and a wireless output. The biometric input may be a sensor pad on the transaction authentication card that measures blood flow patterns, temperature, and/or fingerprint patterns to identify a user to permit access. The transaction authentication card is preferably substantially rigid, but may be formed to have some flexibility. Power to the transaction authentication card may be accomplished through an internal battery that is optionally rechargeable. Biometric data is stored on the card only and used for user verification. Biometric data will not be transferred from the card. If authorized biometric data is authenticated the card will transmit a wireless access code to a proximity reader or transaction equipment.

21. A method, executable by a transaction authentication card including a biometric sensor, processor and memory for enrolling a user, comprising:
-
receiving a biometric of a user;
transforming said biometric into data, said data being representative of said biometric; and
storing data in a memory of said transaction authentication card, whereby said user is enrolled for use of said transaction authentication card. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A method of granting access to a user in a system employing a security module and a transaction authentication card, comprising:
-
receiving a biometric of a user via a transaction authentication card;
enabling an operation mode of said transaction authentication card;
validating said received biometric to determine if biometric matches an authenticated user;
receiving a signal from a security module; and
sending a authentication signal to said security module when said received biometric is validated and said signal has been received by said transaction authentication card. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A transaction authentication card, comprising:
-
a body for at least partially encompassing a circuit board;
a biometric sensor communicatively coupled with the circuit board and disposed in the body, the biometric sensor for sensing a biometric feature of a user;
a memory disposed upon the circuit board in the body, the memory for storage of biometric data;
a processor disposed upon the circuit board in the body, the processor communicatively coupled with the memory and biometric sensor, the processor for retrieving stored biometric data from the memory, the processor having a biometric algorithm for comparing the biometric feature of the user with the stored biometric data; and
a wireless transmitter capable of generating a wireless signal, wherein said wireless signal is transmitted on a one-to-one validation of the biometric feature, the wireless signal being based upon a set of minutia points. - View Dependent Claims (36, 37, 38, 39, 40, 41)
