I am currently planning a thesis that involve scanning fingerprints and storing the data in a database. The problem is that I do not know if it is possible for me/us to get the fingerprint data or variables scanned by the fingerprint scanner.
I tried searching on google, of course, but I don't see any information on how to display the data in a form such as binary. I'm not sure if I can extract the data from the Arduino then store it in a website/database (---which to be fair, since fingerprints can be confidential, I understand if some articles don't provide a sample.)
Is it possible to get and extract the fingerprint scan data? For example, converting the scanned data in to a binary representation (011010101 etc.)
