Biometric Devices

Windows 7 and later implement support for Biometric devices. The Windows Biometric Framework (WBF) is a generic biometric architecture in Windows 7 and later versions of Windows.

WBF includes an IOCTL-based driver interface known as the Windows Biometric Driver Interface (WBDI) as well as a Windows service called the Windows Biometric Framework API (Windows) (WBS). WBS is also referred to as the WinBio service. WBDI drivers respond to requests from the WinBio service. WBF also includes Windows log-in support.

This documentation describes the WBDI. Windows Biometric Framework API (Windows) (WBS) is documented separately in the Windows SDK.
