Abstract:
A passive, one-time password device 102 is claimed along with a method of use. The device has a fingerprint authentication engine 120 and a wireless communication module 110. The device 102 is passive, and therefore powered only by energy harvested from a radio-frequency (RF) excitation field. The device 102 is configured to use the wireless communication module 110 to wirelessly communicate a one-time password 142 responsive to verifying the identity of a bearer of the device 102 using the fingerprint authentication engine 120. The authentication engine may also include a fingerprint sensor, which may be an area-type sensor, a processing unit and a memory, with identity confirmed with reference to fingerprint data stored in the memory. The device may perform an enrolment process in order to generate the reference fingerprint. The device may be arranged to receive a continuous radio-frequency excitation field while a fingerprint process is taking place, in response to a command from an RFID reader, and if the reader has waited longer than a predetermined threshold, to send a request for a wait time extension to the RFID reader.
