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.

• Allows to develop biometric applications that verify a scanned fingerprint against a previously stored fingerprint (1-to-1 matching).
• Both Free Fingerprint Verification SDK and VeriFiinger SDK are based on the same technology except that VeriFinger SDK is a commercial SDK that offers much more capabilities 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).  Also, 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.

The table below shows the differences between Free Fingerprint Verification SDK and Verifinger SDK:

Free Fingerprint Verification SDK contains:

• Fingerprint feature extraction and matching algorithm
• Support modules for fingerprint scanners
• Programming samples in different languages for guiding the developers of biometric applications:
  • C++
  • C#
  • Visual Basic .NET
  • Visual Basic 6
  • Java
  • Delphi 7
• SDK documentation

• Computer with x86 compatible processor running at 1GHz or better;
• Microsoft Windows 2000/XP/2003/2008/Vista/7 operating system;
• Microsoft .NET framework 2.0 (for .NET components);
• Microsoft Visual Studio .Net 2005 or newer, or Microsoft Visual Basic 6 (for application development) or Delphi IDE.
• A fingerprint scanner that is supported by Free Fingerprint Verification SDK;

Free Fingerprint Verification SDK supports various fingerprint scanners and is able to verify a scanned fingerprint against another fingerprint stored in a database. Below is the list of supported scanners on 32-bit operating systems:K;

Free Fingerprint Verification SDK is a freeware product, thus you can use it for developing your own products, as well as distributing them without paying any fees to Neurotechnology.
The Software Licensing Agreement contains a list of proprietary restriction and limitations, so please read it before starting using Free Fingerprint Verification SDK.
The SDK does not require any registration or internet connection for using it or deploying products based on it.

• VeriFinger SDK– For developing stand-alone or web-based fingerprint identification solutions. Free Fingerprint Verification SDK is based on the same fingerprint recognition technology, but the VeriFinger technology offers much more capabilities, including biometric identification (1-to-many matching), unlimited database size, components with advanced functionality and support for all major desktop and mobile platforms.
• VeriLook SDK– For developing stand-alone or web-based face identification solutions. The VeriLook SDK includes Face Verification component, which is designed for using face biometrics in a similar scenario like Free Fingerprint Verification SDK
• MegaMatcher SDK– For development of large-scale fingerprint, face, iris, voice and palm print identification products.
• NCheck Bio Attendance– An end-user biometric system designed to automate attendance control in a wide range of business applications, from employee time tracking to check-in at events, clubs, clinics, public and commercial facilities.
