ScanFinger v1.07 An application to capture a fingerprint scan using WinBIO

Welcome to ScanFinger, A freeware application which demonstrates capturing a raw fingerprint scan using the Windows Biometric API.

The application demonstrates how to use the "WinBioCaptureSampleWithCallback" API to capture a scan while keeping the UI responsive. Once a scan is captured, it will immediately initiate another scan so you can get a feeling for how finger pressure affects the capture.

When a fingerprint is captured the UI should look like the following:

ScanFinger sample

For the hackers among you, please note that the image above does not contain my actual fingerprint. Instead the screen capture above has been doctored to show a "Google Image Search" fingerprint instead. You can zoom in / out, best fit the image to the window and copy the image to the clipboard for inspection with a image processing program etc. Also included in the download is the source code and a VC project to build the binary. The enclosed zip file contains the ScanFinger source code and precompiled binaries. The program is designed for Windows 7 or later. The prebuilt Unicode release binary in the ReleaseU directory in the download is dynamically linked to the VC 2017 MFC DLL. If you do not have this installed then you can download it from If you want to build the source code, then you must have VS 2017 or later installed. A VS 2017 solution is included in the download.
