Abstract:
1. A biometrically authenticated portable RFID access device that selectively permits energization by a tag reader, comprising: a biometric sensor for measuring a live biometric parameter of an unverified user; a stored biometric template corresponding to a previously measured biometric parameter of an authorized user; an authenticator for comparing the live biometric parameter of the unverified user to the stored biometric template and producing an authorization signal when the live biometric parameter matches the stored biometric template; and an electronic switch responsive to the authorization signal from the authenticator, the electronic switch acting to enable the RFID access device to respond to energization by the tag reader only when the authorization signal from the authenticator indicates that the live biometric parameter matches the stored biometric template, wherein the RFID access device is programmable in an RFID tag programmer selected from an installed base of RFID programmers used for programming RFID access devices that do not include associated biometric sensors.
