IDE - An Integrated Development Environment (IDE) is a software that assists programmers to develop software. It normally consists of a source code editor, a compiler and/or interpreter, build-automation tools, and (usually) a debugger. The Fingerprint SDK ActiveX Component can be used in many IDEs, like Microsoft Visual Studio and Borland Delphi.
DLL - A Dynamic Link Library (DLL) is a shared library used in Microsoft Windows. A single instance of a shared library can be used by many running programs without being replicated for each program, saving RAM and disk space. The Fingerprint SDK library can be used as a Windows DLL.
SDK - A Software Development Kit (SDK) is a set of development tools, documents, libraries and/or sample codes that allows a programmer to create applications for a certain software package. The Fingerprint SDK allows a programmer to create applications with biometric capabilities.
FRR - The False Rejection Rate (FRR) is defined as the percentage of identification instances in which false rejection occurs. It's normally expressed as a probability.
FAR - The False Acceptance Rate (FAR) is the measure of the likelihood that the biometric security system will incorrectly accept an access attempt by an unauthorized user.
DPI - The Dots per Inch (DPI) measure indicates the resolution of images. The more dots per inch, the higher the resolution. The DPI is an important information about fingerprint images, affecting both the image quality and matching accuracy.
Template - A template is the feature set extracted from a fingerprint image. The verification and identification functions in Fingerprint SDK library works only with templates. Once the template is extracted the library doesn't need the fingerprint image anymore for any verification or identification process.
Callback - The callback scheme is used in event-driven programs where the program registers a function (a "callback handler") to handle a certain event. The program does not call the handler directly: when the event occurs, another program or library or even the operating system calls the handler, passing it arguments which describe the event.
ActiveX - This is the Microsoft specification for reusable components. ActiveX is based on the Component Object Model (COM), an open standard that specifies how components interact and interoperate. Somewhat like a DLL, ActiveX allows packaging code to create highly reusable components.
regsvr32 - This is a tool to register and unregister Object Linking and Embedding (OLE) controls, such as DLLs and ActiveX controls. For further info about this tool, check the Microsoft's regsvr32 page.
JNI - The Java Native Interface (JNI) is a programming framework that allows Java code running in the Java Virtual Machine (JVM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages, such as C, C++ and assembly.
Java applet - A Java applet is a Java program that can be included as part of a web page.
