Biometrics.Identify Method (POS for .NET v1.14 SDK Documentation)
3/2/2014
Captures biometrics data, compares it to an array of BiometricsInformationRecords, and then returns a rank ordered array of indexes.

public abstract function Identify (
maximumFalseAcceptRateRequested : int,
maximumFalseRejectRateRequested : int,
falseAcceptRatePrecedence : boolean,
referenceBirPopulation : IEnumerable<BiometricsInformationRecord>,
timeout : int
) : int[]
Parameters
- maximumFalseAcceptRateRequested
The requested FAR criterion for successful verification.
- maximumFalseRejectRateRequested
The requested FRR criterion for successful verification.
- falseAcceptRatePrecedence
If both criteria are provided, this parameter indicates which takes precedence. falseAcceptRatePrecedence indicates that maxFARRRequested takes precedence; falseRejectRatePrecedence indicates that maxFRRRequested takes precedence.
- referenceBirPopulation
A collection of BiometricsInformationRecord properties against which the Identify match is performed.
- timeout
Maximum number of milliseconds to try a successful biometric capture before failing.
Remarks
This function captures biometric data from the attached device within the allocated time-out, and compares it against a set of BiometricsInformationRecord properties in referenceBirPopulation. It then returns a rank ordered array of referenceBirPopulation indexes.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread-safe. Any instance members are not guaranteed to be thread-safe.
