1. A biometric system that uses readings from a plurality of biometrics of a user, comprising:

  • a first biometric reader delivering a first measured biometric;

    a first biometric matching engine, wherein;

    the first biometric matching engine processes the first measured biometric to produce a first value, the first value is indicative of a likelihood that the first measured biometric matches a first stored biometric reading, and a plurality of first values are gathered prior to the first value;

    a second biometric reader delivering a second measured biometric;

    a second biometric matching engine, wherein;

    the second biometric matching engine processes the second measured biometric to produce a second value, the second value is indicative of a likelihood that the second measured biometric matches a second stored biometric reading, a plurality of second values are gathered prior to the second value, and at least one of;

    the first and second biometric readers measure a different biometric, or the first and second biometric matching engines use a different algorithm; and

    a processor that;

    normalizes the first value according to the plurality of first values, normalizes the second value according to the plurality of second values, and determines if the user is matches to a person using the normalized first and second values.
