Plug-in Architecture

Biometric devices are manufactured in a wide variety of types and configurations. The Windows Biometric Framework addresses this variety by providing an extensible architecture that enables third party developers to create custom plug-in components. The primary component is a software object called a biometric unit. Biometric units expose the capabilities of a device to the framework through a standard interface that consists of sensor, engine, and storage adapters. Biometric units and their constituent components are discussed in the following topics.

In this section


Biometric Unit

A software object that exposes the capabilities of a biometric device to the framework through a standard interface.


Adapters connect a biometric unit to its underlying hardware and supply any functionality that may be missing from the sensor hardware. There are three types of adapters that you can create: sensor, engine, storage.

Biometric Unit Life Cycle

Every biometric unit is created, configured, and eventually deleted.

Adapter Performance Requirements

In order to give users a good experience with Windows biometrics, adapters must meet certain performance requirements.
