- Frame Transfer (should actually be called 'overlap') Frame transfer refers to the captured image getting transferred to a masked pixel array storage area (quick step) so it can be read out from there (slow step). The real benefit of FT comes when overlap is applied, so that a new image can be captured while the previous is read out.
- Vendors can have a single driver binary that can work with legacy stacks and WBF, but the two cannot operate simultaneously. WBF will only operate if the device can be opened with exclusive access. The second named section contains registry values for the plug-in adapters. The sample uses the Microsoft-provided sensor adapter and storage adapter.

Vendors can provide an INF file to install a WBDI driver.
The following is a list of guidelines for biometric device installation. The code examples in this topic are taken from the WudfBioUsbSample.inx file of the WudfBioUsbSample:
WBDI drivers should specify a class of 'Biometric.' Set ClassGuid equal to the value that corresponds to GUID_DEVCLASS_BIOMETRIC in Devguid.h:
In your .HW section, provide AddReg directives to specify three sections that contain entries to be added to the registry:
Provide the named sections referred to in the .HW section. The [Biometric_Device_AddReg] section sets values for the biometric device, including the exclusive flag and system wake/device idle. To be recognized by Windows Biometric Framework, UMDF-based WBDI drivers must set the 'Exclusive' value to 1. The first two lines of the [Biometric_Device_AddReg] section specify access control list (ACL) rights so that the device can only be opened by an administrator or the local system account. When you specify these ACL rights, third-party applications cannot open the device and capture fingerprint data when the WinBio service is not running. For example:
A WBDI driver that exposes functionality to a legacy (non-WBDI) biometric stack should set the Exclusive value to zero. If this value is set to zero, the Windows Biometric Framework does not attempt to control the device and the device is not exposed through WBF.

The second named section contains registry values for the plug-in adapters. The sample uses the Microsoft-provided sensor adapter and storage adapter. This section also enables Windows log-in support by setting the SystemSensor value:
Finally, the third section sets the following registry values for the database service. The identifying GUID must be unique for each vendor database of a certain format. For instance, in this code example from the sample, change 6E9D4C5A-55B4-4c52-90B7-DDDC75CA4D50 to your own unique GUID in your INF file.
How do I find a suitable driver for my pc Webcam? - Microsoft .... In addition, do not forget that manufacturers of webcams strongly recommend installing the latest drivers. If you do not have the CD and installation files for your webcam, first of all, try to find them on the manufacturer's official website. If you could not find them there, do not hesitate to download free webcam drivers from our website.
To differentiate WBDI and legacy drivers, vendors must set a Feature Score for the driver in the INX file. Feature Score is not set in the WudfBioUsbSample sample. For more information about setting a Feature Score, see Ranking a Biometric Driver on Windows Update.

In order to replace a WBDI driver with a legacy driver, use the following procedure:
