1. A peripheral biometric sensing device for use with a computer and a peripheral card including a processor, the peripheral biometric sensing device comprising:
- a housing;
a biometric information input means disposed within the housing for capturing biometric data and providing a first signal in, dependence thereon;
a peripheral card interface disposed within the housing for interfacing with the peripheral card and for receiving the first signal and providing same to the peripheral card for use in user authorisation performed by the processor;
means for detecting a presence of a peripheral card interfacing with the peripheral card interface and for providing an indication of the presence or absence of the peripheral card;
data transfer means for providing data in dependence upon the captured biometric data to the computer, the data transfer means comprising means responsive to the indication for transmitting the first signal to the system in the absence of a detected peripheral card and for transmitting first signal to the peripheral card and a second signal received from the peripheral card to the syste if a peripheral card is detected as being present; and
means for receiving a second signal from the peripheral card, the second signal being created by the processor of the peripheral card in dependence upon the first signal, and providing the second signal to the data transfer means.

Abstract
A transducer is provided with an integral smart card reader. For security applications the transducer is a biometric information input device. The device provides co-operative operation of the smart card and the transducer to provide user specific processing of biometric information provided by the user. Because of the integral smart card reader, tampering and monitoring of security operations is prevented.

5. A device for use with a system comprising:
-
a housing; a transducer disposed within the housing for capturing biometric information and converting the biometric information into a first signal; a peripheral card interface disposed within the housing for accepting a peripheral card including a processor; means for detecting a presence of a peripheral card interfacing with the peripheral card interface and for providing an indication of the presence or absence of the peripheral card; means for providing the first signal to the peripheral card interface; and
data transfer means for receiving the first signal and coupled with the peripheral card interface for receiving a second signal therefrom, the second signal being created by the processor of the peripheral card in dependence upon the first signal, and responsive to the indication for transmitting the first signal to the system in the absence of a detect peripheral card and for transmitting first signal to the peripheral card and a second signal received from the peripheral card to the system if a peripheral card is detected as being present. - View Dependent Claims (6, 7, 8, 9)

10. A method of identifying a user of a computer system provided with a peripheral device comprising a transducer, a peripheral card interface, and a data transfer means comprising the steps of:
-
providing biometric information to the transducer; detecting a presence of a peripheral card interfaced with the peripheral card interface, the peripheral card including a processor; if a peripheral card is detected, using the processor of the peripheral card for transforming data indicative of the biometric information and provided from the computer system into a first signal and providing the first signal to the data transfer means; if a peripheral card is not detected, providing a different signal based on the data to the data transfer means; transmitting the signal received by the data transfer means to the computer. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A device for use with a system comprising:
-
a housing; a transducer disposed within the housing for capturing biometric information and converting the biometric information into a first signal; a peripheral card interface disposed within the housing for accepting a peripheral card, the peripheral card including a processor; means for providing the first signal to the processor of the peripheral card; means for receiving a second other signal from the peripheral card interface, the second other signal being formed in dependence upon processing of the first signal by the processor of the peripheral card; means for detecting a peripheral card interfacing with the peripheral card interface and for providing an indication of a presence or an absence of the peripheral card; a transceiver for receiving at least one of the first signal and the second other signal from the peripheral card interface responsive to the indication for transmitting the first signal to the system in the absence of a detected peripheral card and for transmitting first signal to the peripheral card and a second signal received from the peripheral card to the system if a peripheral card is detected as being present. - View Dependent Claims (18)
