Free Fingerprint Verification software development kit is a freeware SDK designed for adding fingerprint verification functionality into various applications. The SDK is most suitable for developing biometric logon applications, but it can be used also for any other application that do not require to store more than 10 fingerprints.

The Free Fingerprint Verification SDK functionality allows reading fingerprints from scanners and performing fingerprint verification (1:1 matching) only. Quality control can be applied to accept only good quality fingerprints from fingerprint scanners.

Microsoft Windows 7, Vista & XP operating systems are supported.
