This fingerprint identification software development kit provides client-server ActiveX components for Windows and Linux. It comes with drivers for popular fingerprint scanners and sensors, and offers sample codes for C, C++, C#, VB, VB .NET, Java, and Delphi. Libraries and source codes are also available.

The software comes with drivers for major fingerprint scanners and sensors, making the identification process smooth. VeriFinger Extended SDK supports programming languages such as C, C++, C#, VB, VB .NET, Java, and Delphi, with samples to illustrate how to use the software in each language. The SDK package also offers libraries and source codes making it easy to integrate into any system.
In the VeriFinger Extended SDK distribution package, you get three VeriFinger DLL/library installation licenses, SDK documentation, and specific components for Windows and Linux. The general components for MS Windows include drivers for image input from various scanners and sensors. These include DigitalPersona U.are.U, SecuGen Hamster III, BiometriKa FX 2000, Tacoma CMOS, Fujitsu MBF200, Identix DFR2090, Cross Match Verifier 300-USB, Testech Bio-i, Digent Izzix FD1000, TouchChip, Startek FM200, Ethenticator scanners, Atmel FingerChip, AuthenTec AES4000, and AuthenTec AF-S2 sensors.
The VeriFinger Extended SDK package also includes source codes of VeriFinger DLL usage sample application. Source codes in C/C++ (two samples: Win32 API and MFC), C#, Java, Visual Basic, Visual Basic .Net, Visual Basic for Applications, and Delphi 6 are included. These illustrate how to use the software in various programming languages.
The client-side ActiveX components include a fingerprint scanning component, a fingerprint visualization control that displays fingerprints, a VeriFinger wrapper that wraps VeriFinger DLL into a component that supports COM and does features' extraction in the client-side. In some cases, it could be used on the server-side. Additionally, there is a WWW client component, which communicates with the WWW server-side component via HTTP.
The server-side ActiveX component includes a matching server that identifies and verifies fingerprints on the server-side. There is also a WWW server-side component that performs various tasks using the matching server and VeriFinger wrapper and passes the results to the WWW client component. The VeriFinger wrapper component is required on the server-side. With all these features, VeriFinger Extended SDK is a reliable fingerprint identification software that provides accurate results with a high level of security.
Version 4.2: Improved reliability, reduced fingerprint template size, 50% faster matching, support for new scanners.
