Freeware SDK and components for biometric application development for Windows platform. Most suitable for developing biometric logon applications.
Allows reading fingerprints only from scanners, storing up to 10 fingerprint records in an internal database and performing fingerprint verification (1-to-1 matching) only.
SDK functionality is based on a simplified version of VeriFinger algorithm. Quality control can be applied to accept only good quality fingerprints from fingerprint scanners.
Includes programming samples in C++, C#, Sun Java 2, Visual Basic 6, Visual Basic .NET and Delphi 7. Supports 60+ major fingerprint scanners and sensors:
