Abstract:
An RFID device 102, 140 comprises an antenna 108, a passive RFID communication module 110 and a passive biometric authentication module 120. The passive RFID communication module 110 is configured to transmit data to an RFID reader 104 without the use of encryption. However, the RFID device 102, 140 is configured such that initially power is supplied only to the passive biometric authentication module 120 until the biometric authentication module 120 has verified the identity of a user, whereupon power is supplied to the passive RFID communication module 110 to permit communication. The RFID device 102, 140 is thus less vulnerable to sniffing attacks than conventional unencrypted RFID tags because the device 102, 140 will hold its data securely until an authorized biometric identifier is presented to it.
Abstract:
A method of manufacturing biometric RFID devices comprises producing a plurality of identical biometric identification devices202, 302, 402 that are each adapted to receive at least two different types of RFID module 240, 340, 440a, 440b, and installing a respective RFID module 240, 340, 440a, 440b into each of the devices 202, 302, 402 corresponding to a selected RFID protocol.
Abstract:
The present invention relates to overcoming some of the physical problems associated with putting a biometric sensor (40) into the body of an electronic card (10), such as a smart card. A disclosed method of manufacturing an electronic card (10) including a biometric sensor (40), comprises providing a preformed card body (20) including a circuit (30) having contacts (32) for connection to a biometric sensor (40), the contacts (32) being embedded within the preformed card body (20), removing material from the preformed card body (20) to form a cavity (50) in the preformed card body (20) to expose the contacts (32), coating walls (54) of the cavity with an adhesive epoxy (56), and connecting a biometric sensor (40) to the contacts (32) using an conductive epoxy (52). Also disclosed is an electronic card (10) including a biometric sensor (40) manufactured by this method.

Abstract:
A method of power optimisation in an RFID device includes harvesting power from a radio-frequency excitation field using an antenna, powering a biometric authentication unit and an RFID communication module using the harvested power from the antenna; monitoring the voltage of the power supplied to the biometric authentication unit, and controlling a clock speed of a processing unit of the biometric authentication unit based on the monitored voltage by operating the processing unit at a higher clock speed when a high voltage level is detected and at a lower clock speed when a low voltage level is detected.

Abstract:
A passive RFID device may include a fingerprint authentication engine having a processing unit and a fingerprint scanner. The fingerprint authentication engine is capable of performing both an enrolment process and a matching process on a fingerprint of a finger presented to the fingerprint scanner.
