Hand geometry biometrics on a payment device

摘要

The present invention discloses a system and methods for biometric security using multiple biometrics in a transponder-reader system. The biometric security system also includes a biometric sensor that detects biometric samples and a device for verifying biometric samples. In one embodiment, the biometric security system includes a transponder configured with a biometric sensor. In another embodiment, the system includes a reader configured with a biometric sensor. In yet another embodiment, the present invention discloses methods for proffering and processing multiple biometric samples to facilitate authorization of transactions.

主权项

1. A Radio Frequency (RF) payment device comprising:
a RF transponder configured to receive a device authentication code from an RFID Reader communicatively coupled to a network; a unique device encryption key corresponding to a device identification code associated with the RF payment device; a biometric sensor configured to detect a biometric sample to create biometric sample data,
wherein the biometric sensor is configured to detect an inauthentic biometric sample based on biometric scan characteristics, andwherein the biometric sensor is operable as a switch to place the RF transponder in more than one mode; and a device authentication circuit configured to use the unique device encryption key to encrypt the device authentication code and a device account code associated with the RF payment device to create an encrypted device authentication code and an encrypted device account code; wherein the RF transponder is configured to transmit at least one of the encrypted device authentication code and the encrypted device account code to the RFID Reader; and wherein the RF transponder is configured to be operable in the more than one mode including a selectivity mode and an inclusivity mode, wherein the selectivity mode includes enabling purchase of an item using a selected account number and the inclusivity mode includes the RF transponder in an operational mode permitting the RF transponder to be responsive to interrogation.
