Free Fingerprint Verification SDK

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.

After downloading please unpack the archive with the SDK and review the files in Documentation folder for further instructions.

Features and Capabilities

Free Fingerprint Verification SDK allows to develop biometric applications that verify a scanned fingerprint against a previously stored fingerprint (1-to-1 matching). The SDK is based on the same technology as VeriFinger SDK. The difference is that the VeriFinger SDK is a commercial SDK that offers much more capabilites for software developers.

Free Fingerprint Verification SDK does not allow to develop applications that read fingerprint images from files or perform fingerprint identification (1-to-many matching). The number of stored fingerprint templates is limited to 10 records in the application's database.

The VeriFinger SDK allows to develop a wide range of biometric applications that identify fingerprints taken from fingerprint scanner or image files against fingerprints stored in a database (1-to-many matching). Also, the VeriFinger SDK does not have any limitations on fingerprint database size and allows to develop both standalone PC-based and Web-based application that use client-server architecture.

The VeriFinger SDK contains a wrapper that allows easy transition from Free Fingerprint Verification SDK to VeriFinger SDK.
