Raspberry Pi

There’s a Raspberry Pi Python Library for this fingerprint scanner if you look at the post by user jeanmachuca in the Pi forums.

There appears to be an article that uses the GT-511C1R with a Raspberry Pi as a server and SQLite [ FingerScanner: Embedding a Fingerprint Scanner in a Raspberry Pi ]. Based on this information, it’s possible to have remote management of a database on multiple fingerprint scanners from one server.

Node.js

There’s an example in Node.js with an API in the-AjK's GitHub repository.

BeagleBone Black

There's a BeagleBone Black Python Library by user JamesMarcogliese_'s capstone design team.

.NET
