Abstract: A portable, hand-held biometric identification device includes a processor and a memory coupled to the processor. The memory stores user interface software for operating the device and a local data base of biometric data. The device includes a replaceable battery to provide power to the device and power management. The device includes a fingerprint sensor to take a measurement of a fingerprint image and a second biometric sensor to take a measurement of a second biometric phenomenon. The device includes a non-biometric sensor for determining or recording location and one or more controls for a user to provide input. The device also includes a radio configured to transmit an indication of one or both of the fingerprint image and the second biometric phenomenon to another device and an audio or visual output to tell the user of success or failure for various operations of the device.

Abstract: A portable biometric identification device includes a processor and a memory operably coupled to the processor. A biometric sensor configured to take a measurement of a biometric phenomenon is operably coupled to the memory. A wireless transceiver is configured to transmit at least an indication of the measurement of the biometric phenomenon to another device. The method may include capturing one or more sets of biometric data and transmitting the one or more sets of biometric data to a local server. The method may also include receiving at the local server at least one of the one or more sets of biometric data and comparing the manipulated data to entries of a local data base before sending the biometric data on to a remote data base.
