Captures biometrics data and compares it against a designated Biometrics Information Record.

Namespace: Microsoft.PointOfService
Assembly: Microsoft.PointOfService (in microsoft.pointofservice.dll)

public abstract BiometricsVerifyResult Verify (
    int maximumFalseAcceptRateRequested, 
    int maximumFalseRejectRateRequested, 
    boolean falseAcceptRatePrecedence, 
    BiometricsInformationRecord referenceBir, 
    boolean adaptBir,

public abstract function Verify (
    maximumFalseAcceptRateRequested : int, 
    maximumFalseRejectRateRequested : int, 
    falseAcceptRatePrecedence : boolean, 
    referenceBir : BiometricsInformationRecord, 
    adaptBir : boolean, 
    timeout : int
) : BiometricsVerifyResult

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.
  • adaptBir
    Indicates whether the referenceBir will be adapted from information taken from the captured BiometricsInformationRecord.
  • 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 the referenceBir. If the match is successful as indicated by a positive result, the Service tries to adapt the referenceBir from information take format the captured BiometricsInformationRecord.

The data formats of the two BiometricsInformationRecord may be different because the format depends on the physical device model.

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.
