Creates biometric samples for use by Match-On-Card and enabled Match-On-Card implementations that require prematch data before matching operations.

Parameters

  • prematchDataBir
    The BiometricsInformationRecord property that contains prematch data previously emitted by the associated Match-On-Card Library.

Remarks

This method processes biometric samples that are suitable for Match-on-Card. It enables Match-On-Card implementations that require the retrieval of prematch data from the card before the matching operation.

Because smart cards generally cannot capture and process biometric samples, the Match-On-Card functionality needs a host to perform off-card operations such as sample acquisition and feature extraction. In this case, the card needs the host to perform an operation based on prematch data that is retrieved from the card.

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.
