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-to-1 matching) only. Quality control can be applied to accept only good quality fingerprints from fingerprint scanners.

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 includes a biometric engine, which is designed and optimized for fingerprint verification task. The engine is compatible with the biometric technology from VeriFinger SDK, which offers much more advanced 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-all 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-all matching). Also, the VeriFinger SDK does not have any limitations on fingerprint database size and allows to develop both standalone and network-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.
