Raspberry Pi Example Code

There’s a Raspberry Pi Library for this fingerprint scanner it looks like => https://www.raspberrypi.org/forums/viewtopic.php?f=61&t=74178 .

There appears to be an article that uses the GT-511C1R with a Raspberry Pi as a server and SQLite [ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801596/ ]. Based on this information, it’s possible to have remote management of a database on multiple fingerprint scanners from one server.

Node.js Example

There’s an example in Node.js with an API. I have not tested this feature before but try looking at this GitHub repository => https://github.com/the-AjK/GT-511C3 .
