Transaction authentication card
First Claim
1. A transaction authentication card, comprising:
- a body for at least partially encompassing a circuit board;
a biometric sensor communicatively coupled with the circuit board;
a memory coupled with 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 the biometric sensor, the processor for retrieving stored biometric data from the memory, the processor exclusively performing enrollment of the biometric feature of the user, the processor executing a biometric algorithm for comparing the biometric feature of the user with the stored biometric data;
a security device disposed within the body, the security device erases data from said memory when said body is opened, wherein said security device includes a light sensitive diode and erases data from said memory when said light sensitive diode is exposed to light; 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.

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.
