Python library for ZFM-20 fingerprint sensor
The PyFingerprint library allows to use the ZhianTec ZFM-20 fingerprint sensor on the Raspberry Pi or other Linux machines.
Note: The library is inspired by the C++ library from Adafruit Industries:

Package building
Note: This should work properly on Debian 7 (Wheezy) and Debian 8 (Jessie).
First install the packages for building:
~$ sudo apt-get install devscripts
Than clone this repository:
~$ git clone https://github.com/bastianraschke/pyfingerprint.git
Build the package:
~$ cd ./pyfingerprint/src/
~$ debuild
Installation
Install the built Debian package:
~$ sudo dpkg -i ../python-fingerprint*.deb
Install missing dependencies:
~$ sudo apt-get -f install
Allow non-root user "pi" (replace it correctly) to use the serial port devices:
~$ sudo usermod -a -G dialout pi
~$ sudo reboot
