Windows Hello, fingerprint sensors and facial recognition, in a native Delphi and C++ Builder component. sgcBiometrics talks straight to the Windows Biometric Framework, so the sensor, the capture and the match all happen on the machine your app is already running on.
Fingerprint, facial recognition and Windows Hello for Delphi and C++ Builder, built on the Windows Biometric Framework. Design-time VCL components, 100% native code, full source with the Professional edition.
Drop one component on the form, choose the sensor pool and the biometric type, and call Verify. Windows captures, Windows matches, and your event handler is told whether it was the right person.
Capture and verify fingerprints through the Windows Biometric Framework. Works with any WBF-compatible fingerprint sensor, and with the system or the private sensor pool.
Camera-based face detection and presence verification, compatible with standard webcams and with infrared cameras for anti-spoofing.
Passwordless sign-in on top of the biometric infrastructure already built into Windows 10 and Windows 11, covering PIN, fingerprint and face.
Guide users through enrollment with the built-in UI prompts, manage the enrolled credentials, and handle re-enrollment when a finger or a face has to be registered again.
Biometric credentials are stored and managed through the Windows Credential Manager, with support for multiple users and multiple credential types.
OnCapture, OnVerify and OnIdentify fire asynchronously with full status reporting, so a scan never blocks the VCL message loop.
// Verify the person at the fingerprint reader
procedure TForm1.VerifyFingerprint;
begin
sgcBiometric1.SensorPool := spSystem;
sgcBiometric1.BiometricType := btFingerprint;
sgcBiometric1.Verify;
end;
// Windows does the matching, your handler gets the answer
procedure TForm1.OnVerify(Sender: TObject;
const Match: Boolean;
const Identity: string);
begin
if Match then
ShowMessage('Verified: ' + Identity)
else
ShowMessage('Not recognized');
end;Two sensor pools, one API. The system pool shares the reader with the rest of Windows, the private pool gives your application exclusive access for kiosk and embedded scenarios. All features →

sgcBiometrics is not a service. It is a set of native components that call the biometric infrastructure already present in Windows, on the same computer your application is running on.
Capture and matching are performed by the Windows Biometric Framework, the same infrastructure that backs Windows Hello. Your application asks for a verification, it does not handle the sensor itself.
Hardware-backedThe OnVerify event hands you a Match boolean and an Identity, and your application branches on that. No fingerprint image and no face template pass through your code.
Enrolled biometric credentials are stored and managed by the Windows Credential Manager, so your application never has to invent a place to keep them.
Windows Credential ManagerThere is no eSeGeCe service to sign up for and no biometric API key to configure. The components are 100% native code and they ship with full source in the Professional edition, so you can read exactly what they do.
100% native codesgcBiometrics targets Windows 10 or later, on Delphi 10 Seattle through RAD Studio 13 and C++ Builder. A Windows Hello-compatible sensor or camera is required. Compare editions →
A biometric check is a few lines of code, so it belongs wherever a password prompt currently sits.
Replace the login dialog at startup. The user touches the reader or looks at the camera, Windows Hello verifies, and the app opens.
Ask for a fingerprint again before a high-value action is committed, so an unattended workstation cannot be used to approve it.
The private sensor pool gives your application exclusive access to the reader, which is what a kiosk or an embedded terminal needs.
Verify with a fingerprint or with Windows Hello before sgcSign produces a XAdES or PAdES signature, so the key is only used by the person who owns it.
