Python library for ZFM fingerprint sensors

The PyFingerprint library allows to use ZhianTec ZFM-20, ZFM-60, ZFM-70 and ZFM-100 fingerprint sensors on the Raspberry Pi or other Linux machines. Some other models like R302, R303, R305, R306, R307, R551 and FPM10A also work.

Note: The library is inspired by the C++ library from Adafruit Industries: https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library

How to use the library

~$ python /usr/share/doc/python-fingerprint/examples/example_enroll.py

Search an enrolled finger

~$ python /usr/share/doc/python-fingerprint/examples/example_search.py

Delete an enrolled finger

~$ python /usr/share/doc/python-fingerprint/examples/example_delete.py

Download image of a scanned finger

~$ python /usr/share/doc/python-fingerprint/examples/example_downloadimage.py

Generate a 32-bit random number on the ZFM hardware PRNG

~$ python /usr/share/doc/python-fingerprint/examples/example_generaterandom.py
