I have a (relatively two year old) Samsung device that has a fingerprint sensor, however, I don't think it's compatible with the fingerprint sensor option on Zorin, which is honestly ludicrous. Not that I'm criticising the OS or anything. I know it's incompatible because I couldn't get python-validity to work because of this error:
Fingerprint reader support is bad because the manufacturers do not make Linux drivers for them. Has nothing to do with Zorin or any other OS.
As the error states, there is no matching device found.
There are plenty of threads on here that if you search the forum, will give you step by step of everything that must be installed before jumping ahead. Sometimes your reader will be recognized sometimes it won't. If it isn't, there is nothing anyone can do about it since no driver exist for it, the only one who can help you is the manufacturer of the reader.
On a side note: I did manage to get mine working on my Dell... I shut it off 3 days later as the experience of it all was totally underwhelming.
I guess that's true. Windows is the most common operating system used. But if developers developed things for other operating systems, like Linux, they would be able to reach more people. If you know what I mean.
