This ZFM-20 fingerprint library is developed to capture and retrieve fingerprint images from the above sensor module. The main purpose of this library is to use ZFM-20 sensor with PC as low cost fingerprint capture unit and because of that, in-module fingerprint processing and verification functions are not implemented in this library.

ZFM20-LIB is x86 native shared library and its implemented using Lazarus/FPC. This library is developed to use with most of the programming languages which including C, C++, Delphi, FPC, Microsoft .net framework based languages, etc. Object oriented wrappers for this library are available for both .net framework support languages and for FPC.
This version of ZFM-20 Fingerprint capture library is tested with ZFM-20 series serial fingerprint module with CH340G USB to serial converter. Generally this library is design to work with any USB to serial converter which including FT232, CP2101, etc.
ZFM-20 fingerprint capture library is an open source shared library project and it’s source code and compiled binaries are available at https://github.com/dilshan/zfm20-lib. This library is released under the terms of MIT License.
